# TightSpec Tools — Torque Specification Library

Machine-readable register of published fastener torque specifications for heavy-duty trailer, truck, and stationary-engine maintenance. Every value cites its manufacturer source document. Verify current spec with the component manufacturer before servicing.

Fire pump values cover the Hale Muscle Pump and Waterous CS/CSU/CM/CMU families. Wheel-end values follow TMC RP 237B (ATA Technology & Maintenance Council), which distinguishes OILED hub-piloted from DRY stud-piloted at the same nominal 450–500 ft-lb. Some OEM manuals publish 450–500 as a dry value; both are cited here rather than reconciled.

| TMC RP 237B — stud-piloted double cap nut, HEAVY DUTY (1-3/16" ball seat): 15/16"-12, 1-1/8"-16, 1-5/16"-12 | see notes | TMC RP 237B Table 1 | DRY. Same nut sizes as standard, 300 ft-lb higher. Ball seat radius is the deciding feature — measure it. 750–900 is above a 500-class tool. |
| TMC RP 237B — wheel retorque interval | see notes | TMC RP 237B | Retorque 5–100 miles after installation, then every 10,000 miles. Sample at least 30 wheel ends; spot-check no less than every 3 months per location. |
| TMC RP 237B — measuring REMAINING torque | see notes | TMC RP 237B, Torque Measuring Procedure | Never a clicker — it only reports above/below setpoint. Use dial, pointer or digital. Pull in the tightening direction and read the instant the nut begins to move. Keep the wrench 90° to the hub. |
| TMC RP 237B — lubrication & anti-seize | see notes | TMC RP 237B | Hub-piloted IS oiled; stud-piloted is NOT. Anti-seize prohibited on both — its consistency varies and throws torque off. Aluminum wheels: check with the wheel manufacturer. |
| TMC RP 237B — extensions, torque sticks, paint, studs | see notes | TMC RP 237B | One chrome extension maximum, only as long as the job needs; stacked extensions slip. Torque-limiting adaptors are not torque-control devices and must not be used to gather data. Paint max 0.0035" (3.5 mils) on mounting surfaces, never on stud threads. One broken stud: replace it plus the stud either side; two or more: replace all. |
| Snug torque before final (hub- and stud-piloted) | see notes | TMC tire/wheel installation procedure, Table 2-4 | Criss-cross to ~50 ft-lb until seated, then final torque. |

The torque numbers match (375–475 and 325–375) but the stated grade and friction condition do not. Identify the brand and the coating before setting a wrench — a TEXO-coated bolt oiled, or an oiled spec applied to a dry coated bolt, lands in a different clamp load at the same reading. |

Kenworth publishes a separate frame fastener table (Y53-1212-1C1 Table 14). |
| Peterbilt AIR LEAF: 1 NF x 8.5 in spring eye bolt | 225–550 ft-lb (lube condition not stated) | Peterbilt Y53-6113-1E1 §28.9 (01/2026) | Widest published band in the register — a 325 ft-lb spread on one fastener. Confirm the exact application with the suspension manual before setting a tool. |

The Low Air Leaf and Flex Air tables print 125–165 lb-ft as (210–264 N-m). 125–165 lb-ft = 170–224 N-m, which is what the AIR-TRAC table prints for the same fastener on a facing page. The lb-ft column is the reliable one in every case. |

NONE of the 01/2026 manuals repeat the 'clean and dry, do not lubricate' instruction that Kenworth Y53-1212-1C1 (03/17) carried — the current revisions state no lubrication condition at all, while TMC RP 237B publishes the same 450–500 as OILED. |
| PACCAR (current): steel/aluminum disc wheel, double cap nut, standard 7/8 radius ball seat, 3/4-16 and 1-1/8-16 | 450–500 ft-lb (lube condition not stated) | Kenworth Y53-1212-1L1 §28.3; Peterbilt Y53-6113-1E1 §28.3 (01/2026) | Stud-piloted table retained in these chassis families; other 01/2026 manuals carry only the hub-piloted and cast spoke tables. |

| PACCAR (current): wheel cap nut check interval — WEEKLY | see notes | PACCAR 01/2026 operator's manuals — Kenworth Y53-1200-1N1 / 1209-1H1 / 1212-1L1; Peterbilt Y53-6096-1F1 / 6113-1E1 / 6126-1D1 / 6181-1C1 / 6191-1C1 | Every current Kenworth and Peterbilt operator's manual: torque all wheel cap nuts to spec at the first scheduled lube interval, then CHECK AT LEAST ONCE A WEEK. TMC RP 237B calls for 5–100 mi after installation then every 10,000 mi. The OEM interval is far more aggressive than the industry recommended practice. |
| PACCAR (current): OEM statement on wheel torquing equipment | see notes | PACCAR 01/2026 operator's manuals — Kenworth Y53-1200-1N1 / 1209-1H1 / 1212-1L1; Peterbilt Y53-6096-1F1 / 6113-1E1 / 6126-1D1 / 6181-1C1 / 6191-1C1 | Verbatim in all seven current manuals, both brands: 'Contact an authorized dealer for information on the proper installation procedure for the wheels on your vehicle. This is a job you may not be able to do yourself. You need the right torquing equipment to do it.' |
| PACCAR (current): OEM statement on U-bolt tightening | see notes | Kenworth Y53-1200-1N1 §25.5; Kenworth Y53-1212-1C1 p.5-119 | PACCAR proprietary suspension U-bolts must be tightened in a specific sequence, and Kenworth directs owners to an authorized dealer to do it. The 2017 manual is blunter: 'U-bolts are difficult to tighten unless you have the right equipment. If you cannot tighten them correctly yourself, be sure to have them checked and tightened regularly by an authorized dealer.' |
| Volvo: torque values are published as TARGET ± TOLERANCE in N-m, not as a lb-ft range | see notes | Volvo Body Builder Instructions VN/VHD/VAH Sec. 6 Axle and Suspension, USA165006140 (9.2022) / Volvo Body Builder Instructions VN/VHD/VAH Sec. 7 Chassis, Frame, USA138172656 (1.2017) | STRUCTURAL DIFFERENCE FROM PACCAR AND TMC. Volvo publishes a metric target with a symmetric tolerance (900 ±140 N-m) and gives lb-ft only as a conversion. PACCAR and TMC RP 237B publish lb-ft min–max bands. Practical effect: on a Volvo you set the wrench to the target, and the governing number is the N-m one. Volvo's own two sections convert 900 ±140 N-m differently — Sec. 6 prints 664 ±103 lbf-ft, Sec. 7 prints 667 ±111 ft-lb. 900 N-m = 664 ft-lb and 140 N-m = 103 ft-lb, so Sec. 6 is the accurate conversion. Work in N-m on Volvo. |
| Volvo (Hendrickson EX / RADD-HX): balance beam to axle, M24 | 664 ±103 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 6 Axle and Suspension, USA165006140 (9.2022) p.45 | 900 ±140 N-m. Highest published Volvo suspension value. |

Published as a range rather than target ± tolerance — the only row in the table that is. |
| Volvo (Hendrickson EX / RADD-HX): frame suspension bracket to rubber suspension bracket, M16 | 260 ±10 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 6 Axle and Suspension, USA165006140 (9.2022) p.45 | 353 ±14 N-m. Tightest tolerance in the table at ±4%. |

| Volvo (Hendrickson EX / RADD-HX): frame to shock absorber bracket, M16 | 70–92 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 6 Axle and Suspension, USA165006140 (9.2022) p.45 | 95–125 N-m. |
| Volvo: M16 carries THREE different torques in one suspension table | see notes | Volvo Body Builder Instructions VN/VHD/VAH Sec. 6 Axle and Suspension, USA165006140 (9.2022) p.45 | On the same Hendrickson EX / RADD-HX table, M16 appears at 70–92 (shock absorber bracket), 203 ±33 (torque rod) and 260 ±10 lbf-ft (rubber suspension bracket). The bolt size does not determine the spec — the location does. Volvo also directs servicers to use only genuine Hendrickson parts for this suspension. |
| Volvo: load leveling valve to frame fastener | 129 ±22 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 6 Axle and Suspension, USA165006140 (9.2022) p.49 | 175 ±30 N-m. Set after adjusting ride height — RRH-200 at 266 mm frame height is 210 ±5 mm unloaded, RRH-180 at 300 mm is 193 ±5 mm. |
| Volvo T-Ride: leaf spring U-bolts to saddle caps | 369 ±55 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 7 Chassis, Frame, USA138172656 (1.2017) p.69 | 500 ±75 N-m. |

Same pair used at the spring hangers, saddle brackets and V-torque rod frame bracket. |
| Volvo: front spring pins (VNM / VNL) | 63 ±11 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 7 Chassis, Frame, USA138172656 (1.2017) p.67 | 85 ±15 N-m. |
| Volvo: front engine mount isolator (VHD axle back) | 78 ±13 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 7 Chassis, Frame, USA138172656 (1.2017) p.67 | 105 ±20 N-m. VNM and VNL front engine crossmember is 148 ±24 ft-lb (200 ±33 N-m). |
| Volvo: frame rail bolts M6 / M7 / M8 / M10 | 9 ±1.5 / 16 ±3 / 22 ±4 / 44 ±7 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 7 Chassis, Frame, USA138172656 (1.2017) p.5 | Property class 10.9 bolts (Grade 8) with property class 10 nuts. 12 ±2 / 22 ±3 / 30 ±5 / 60 ±10 N-m. |

The most-used value in the frame section — intermediate and closing crossmembers, harness supports and light bar all take it. |
| Volvo: frame rail bolt M16 — crossmembers to frame | 204 ±34 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 7 Chassis, Frame, USA138172656 (1.2017) p.5 | 275 ±45 N-m. Compare Kenworth's frame M16 at 120–160 ft-lb (Y53-1212-1C1 Table 14) — Volvo runs the same nominal frame fastener materially higher. |
| Volvo: frame rail bolts M18 / M22 / M24 | 267 ±44 / 541 ±90 / 667 ±111 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 7 Chassis, Frame, USA138172656 (1.2017) p.5 | 360 ±55 / 730 ±120 / 900 ±140 N-m. |

| Volvo: PTRD-D2 power take-off maximum torque rating | 642 ft-lb (lube condition not stated) | Volvo Body Builder Instructions VN/VHD/VAH Sec. 9 VECU/PTO | Rating, not a fastener spec. SAE1300 flange. Other PTO ratings in the section: 630 ft-lb stationary / 480 ft-lb above 3 mph; 740 ft-lb stationary; 600 ft-lb stationary / 284 ft-lb moving; 500 ft-lb. |
| Lion Electric LionC: wheel nut final torque, M22 x 1.5 hub-piloted two-piece flange nuts | 475 ft-lb LUBRICATED | Lion Electric LionC Maintenance Manual §03-20 Wheel Retorque | A SINGLE TARGET, not a band — the only wheel-nut spec in this register published that way, and it lands exactly on the 475 that TMC RP 237B tells you to set the wrench to. Lubrication is specified to the drop: one drop of SAE 30W motor oil on the first two or three threads of the stud, and two drops between the flange and the nut. |
| Lion Electric LionC: wheel nut snug pass | 50 ft-lb LUBRICATED | Lion Electric LionC Maintenance Manual §03-20 Wheel Retorque | 68 N-m. Run the full sequence at 50 first, then repeat the sequence at 475. |
| Lion Electric LionC: wheel retorque trigger | see notes | Lion Electric LionC Maintenance Manual §03-20 Wheel Retorque | Retorque after 150 km (about 93 miles) of service following any installation of the wheel-to-hub assembly. Sits inside TMC RP 237B's 5-100 mile window. Lion also notes that Hendrickson does not recommend plastic wheel spacers or guards. |
| Lion Electric LionC: wheel nut torque (maintenance procedure sheet) | 450–500 ft-lb (lube condition not stated) | Lion Electric MP-01-33-00-00-003 Verification of the Wheels Nuts (2020-05-28) | PUBLISHED AS A BAND IN ONE DOCUMENT AND A TARGET IN ANOTHER. The MP sheet (Rev 2020-05-28) gives 450-500 ft-lb and states no lubrication condition; the online manual §03-20 gives a single 475 with an exact oiling instruction. 475 is the midpoint, so the two are compatible rather than contradictory — but the MP sheet alone would let a shop run 450 dry. Use §03-20. |
| Lion Electric LionC: specified wheel torque tool | see notes | Lion Electric MP-01-33-00-00-003 Verification of the Wheels Nuts (2020-05-28) | The MP sheet calls for a torque wrench of 0-500 ft-lb. At the 475 target that is 95% of the tool's range. A wrench is generally accurate only across 25-75% of its stated range, so the tool Lion names is being used at the least accurate end of its span. This is the clearest tool-selection argument in the register. |
| Lion Electric LionC: steering ball stud castle nut | 120–170 ft-lb (lube condition not stated) | Lion Electric LionC Maintenance Manual §03-22 Steering System Retorque | 160-230 N-m. Install and secure a cotter pin after torquing. |
| Lion Electric LionC: brake pedal pivot pin and nut | 100 ft-lb (lube condition not stated) | Lion Electric LionC Maintenance Manual §12-12 Brake Pedal Verification | 135 N-m. Lion instructs applying a fresh torque mark afterward for future reference — a documented-torque practice built into the OEM procedure. |
| TMC RP 237B: torque wrench accuracy by wrench type | see notes | TMC RP 237B, Torque Wrench Use and Operating Instructions | Published accuracy, best to worst: beam +/-2%, dial +/-3%, ratcheting clicker +/-4%, break-handle +/-5%. This is why RP 237B tells you to set the wrench to 475 for a 450-500 joint — a +/-5% tool set at 475 still lands inside the band, but the same tool set at 500 does not. |
| TMC RP 237B: checking a nut with a clicker wrench | see notes | TMC RP 237B, Torque Wrench Use and Operating Instructions | If the wrench clicks without the nut moving, the actual torque is HIGHER than the setting. Step the setting up in increments of 50 ft-lb or less until movement is seen. A clicker only tells you which side of the setpoint you are on, so RP 237B says do not use one to measure remaining torque at all. |
| TMC RP 237B: heavy-duty stud-piloted large thread size — VERIFY | 750–900 ft-lb DRY | TMC RP 237B Table 1 vs Kenworth Y53-1212-1C1 Table 20 | DISCREPANCY IN THREAD SIZE, NOT VALUE. Both publish 750-900 ft-lb dry for the heavy-duty 1-3/16 ball seat cap nut, but the largest thread is printed as 1-5/16-12 in the TMC document and 1-15/16-12 in the Kenworth table. The torque is not in question; the thread callout is. Confirm against the wheel before ordering a socket. RESOLVED 8/12: Heil Trailer's torque chart independently agrees with TMC on 1-5/16-12; the PACCAR 1-15/16-12 is a propagated typo. See the resolution entry. |
| Blue Bird BBCV: steering gear mounting bolts | 270–300 ft-lb (lube condition not stated) | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A, p.216 / p.1213 | 366-406 N-m. Highest chassis-level steering value on the bus. Same figure appears as '15 Nut' on the p.1213 chart. |
| Blue Bird BBCV: pittman arm to steering gear nut | 175–185 ft-lb (lube condition not stated) | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A, p.216 / p.1213 | 237-250 N-m. Tightest band of the steering set — only 10 ft-lb wide. Listed as '18 Nut' on p.1213. |

CORROBORATED ACROSS TWO BUS OEMs: Lion Electric publishes the identical 120-170 ft-lb (160-230 N-m) for its steering ball stud castle nut in LionC §03-22. Two unrelated manufacturers, same joint, same number. |
| Blue Bird BBCV: drag link to steering knuckle nut | 120–170 ft-lb (lube condition not stated) | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A, p.216 / p.1213 | 162-230 N-m. Same value at both ends of the drag link. Listed as Drag Link Axle Nut and Drag Link Gear Nut on p.1213. |

| Blue Bird BBCV: steering fastener check interval | see notes | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A, p.216 | Check torque on steering fasteners annually or every 100,000 miles. For severe-duty or off-road operation, every 6 months or 50,000 miles. A published severe-duty split like this is rare and is worth quoting to any district running gravel routes. |
| Blue Bird BBCV: power steering pump mounting (Ford, with or without air compressor) | 70 ±2 ft-lb (lube condition not stated) | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A, p.1213 | Rotate towards front of chassis. |
| Blue Bird BBCV: power steering pump pulley / drive fitting | 42 ±2 ft-lb (lube condition not stated) | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A, p.1213 |  |
| Blue Bird BBCV steering gear: side cover bolts | 180–220 ft-lb LUBRICATED | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A, Torque Chart p.1282 | 244-298 N-m LUBRICATED. Highest value in the steering gear rebuild chart. This chart is one of the few in the whole register that publishes a dry column and a lubricated column side by side. |
| Blue Bird BBCV steering gear: valve housing bolts | 118–138 ft-lb LUBRICATED | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A, Torque Chart p.1282 | 160-187 N-m lubricated. |

The shift lever supplied with the transmission is discarded and replaced with the one in the kit. |
| Blue Bird BBCV: torque converter to flywheel alignment | see notes | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A, Transmission Connections p.729 | Align the converter stud marked with a paint daub to the flywheel mounting hole nearest 12 o'clock to optimise engine and transmission balance. Apply .05 oz of grease 00043655 to the converter pilot circumference. |
| Blue Bird BBCV: the manual mixes two spec formats | see notes | Blue Bird BBCV Ford 7.3L Service Manual Vol 1, 10086432A | Engine mounts and transmission connections are published as TARGET +/- TOLERANCE (258 +/-39). Steering and driveline are published as MIN-MAX RANGES (270-300). Both formats appear in one document, so read which one you are looking at before setting a wrench — this is the same distinction that separates Volvo from PACCAR, except here it is inside a single manual. |
| Spartan chassis (Hendrickson SOFTEK / AIRTEK): clamp group locknuts, 3/4-16 UNF | 280–305 ft-lb (lube condition not stated) | Hendrickson SOFTEK / AIRTEK Technical Procedure, LIT NO 17730-259 Rev B (Jan 2012) | Tighten in even increments of 50 ft-lb. Retorque at 1,000 miles, then annually. APPLICABILITY NOTE: this Hendrickson procedure names Spartan Bus and Spartan Motorhome chassis. Spartan also builds fire apparatus chassis on related front suspensions — confirm the suspension tag before applying this to an apparatus. |
| Spartan chassis (Hendrickson SOFTEK / AIRTEK): steering stop jam nuts, 1/2-13 UNC | 40–60 ft-lb (lube condition not stated) | Hendrickson SOFTEK / AIRTEK Technical Procedure, LIT NO 17730-259 Rev B (Jan 2012) | Set with the axle stops parallel to the beam. |
| Spartan chassis (Hendrickson SOFTEK / AIRTEK): inner wheel bearing adjusting nut, 1-1/2-12 UNF | 200 then 50 ft-lb (lube condition not stated) | Hendrickson SOFTEK / AIRTEK Technical Procedure, LIT NO 17730-259 Rev B (Jan 2012) | Two-stage with a back-off between: 200 ft-lb on a rotating hub, back off one full turn, re-torque to 50 ft-lb, back off one third of a turn, then fit the lock washer. Compare STEMCO PRO-TORQ in this register — 200 rotating, back off hand tight, re-torque 100. Same idea, different numbers. |
| Spartan chassis (Hendrickson SOFTEK / AIRTEK): outer wheel bearing jam nut, 1-1/2-12 UNF | 240–260 ft-lb (lube condition not stated) | Hendrickson SOFTEK / AIRTEK Technical Procedure, LIT NO 17730-259 Rev B (Jan 2012) |  |
| Spartan chassis (Hendrickson SOFTEK / AIRTEK): height control valve lock nuts | 7–10 ft-lb (lube condition not stated) | Hendrickson SOFTEK / AIRTEK Technical Procedure, LIT NO 17730-259 Rev B (Jan 2012) | Ride height adjustment, 5 mm allen on the socket screws. One of the lowest published values in the register — easy to strip. |
| Spartan chassis (Hendrickson SOFTEK / AIRTEK): lubrication and retorque intervals | see notes | Hendrickson SOFTEK / AIRTEK Technical Procedure, LIT NO 17730-259 Rev B (Jan 2012) | Kingpin and tie rod ends: NLGI Grade 2 multipurpose grease at a maximum of 25,000 miles or 90 days, whichever comes first. Front wheel bearings: SAE 80W-90 GL-5 at 15,000 miles. Clamp group retorque at 1,000 miles then annually. |
| Spartan K2 chassis (IFS84 front suspension): drag link castle nut | 150 ±20 ft-lb (lube condition not stated) | Spartan Chassis TSB04-160-001 (Nov 2004) | 130-170 ft-lb. Do NOT reuse the cotter pin — fit a new one. Compare Blue Bird and Lion Electric, which both publish 120-170 for the same style of drag link ball stud. Spartan's floor is 10 ft-lb higher. Applies to K2 chassis with IFS84 and a VDM built on or before 8-27-04. |
| Spartan K2 chassis (IFS84): tie rod tube clamp bolts | 70 ±5 ft-lb (lube condition not stated) | Spartan Chassis TSB04-160-001 (Nov 2004) | 88-102 N-m. The clamp tabs must sit at the top of the tube. |

Darley 1-1/2 AGE Portable Pump Service Manual 1200004 (6/29/06) + Assembly Techniques 1205529 (16 Dec 2015) | NO TORQUE VALUE IS PUBLISHED. The procedure is positional: tighten until the nut contacts the impeller washer, then turn to the next cotter key hole and fit a stainless cotter key. This is the same pattern as pre-4/20/98 Waterous CS/CSU pumps, where the castle nut is set to slot alignment rather than to a number. Two fire pump makers, same approach on the same kind of joint. |
| Darley: general fastener table, SAE Grade 8 clean non-plated | 20–29 (5/16-18) · 35–52 (3/8-16) ft-lb DRY | W.S. Darley 1-1/2 AGE Portable Pump Service Manual 1200004 (6/29/06) + Assembly Techniques 1205529 (16 Dec 2015) | 27-39 N-m and 47-70 N-m. 1/4 NC Grade 8 is 115-172 in-lb (13-19 N-m). Darley publishes a grade-based fallback table for fasteners without a specific callout — useful when a fire pump fastener has no listed value. |
| Meritor conventional wheel end: bearing adjustment procedure | 150 → 50 ft-lb (lube condition not stated) | Meritor Maintenance Manual MM-0409, Wheel-End Components (Rev 11-21) | Staged: 150 lb-ft while rotating the hub at least five full turns, back off one complete turn, retighten to 50 lb-ft while rotating, back off 1/3 turn, then fit the lock ring. THIRD publisher of a staged bearing adjustment in the register — Hendrickson runs 200/50 with the same back-offs, STEMCO runs 200/100. Same architecture, three different number pairs. The procedure style is industry-wide; the values are maker-specific. |
| Meritor conventional wheel end: outer wheel bearing jam nut | 150–225 ft-lb (lube condition not stated) | Meritor Maintenance Manual MM-0409, Wheel-End Components (Rev 11-21) |  |

| Meritor unitized wheel end: wheel adapter bolts | 275 ±25 ft-lb (lube condition not stated) | Meritor Maintenance Manual MM-0409, Wheel-End Components (Rev 11-21) | 373 +/-34 N-m, star pattern, calibrated torque wrench specified. RECHECK EVERY 30,000 MILES or sooner — one of the few wheel-area fasteners anywhere in the register with a published recurring recheck interval. |
| Meritor unitized wheel end: inspection pipe plug | 15 minimum ft-lb (lube condition not stated) | Meritor Maintenance Manual MM-0409, Wheel-End Components (Rev 11-21) | Published as a MINIMUM, like the Waterous CM/CMU body fasteners. Thin coat of sealant on the threads. |
| STEMCO Pro-Torq spindle nut: bearing seating | 200 ft-lb (lube condition not stated) | STEMCO Pro-Torq Installation Wall Chart 571-2994 (Rev 1/20) | Tighten to 200 lb-ft, spin the hub at least one full rotation, repeat the cycle THREE times, then back the nut off one full rotation. |
| STEMCO Pro-Torq spindle nut: bearing adjustment | 100 ft-lb (lube condition not stated) | STEMCO Pro-Torq Installation Wall Chart 571-2994 (Rev 1/20) | 100 lb-ft, spin at least one full rotation, three cycles, then back off one face mark plus the fraction for the axle: steer single-nut 1/6 turn (12 TPI) or 1/4 turn (18 TPI) with a cotter pin, steer double-nut 1/2 turn, drive and trailer 1/4 turn (12 or 16 TPI). Acceptable end play 0.001-0.005 in by dial indicator. |
| STEMCO Pro-Torq: current chart vs the Army M871A3 TM | see notes | STEMCO Pro-Torq Installation Wall Chart 571-2994 (Rev 1/20) vs TM 9-2330-326-14&P (Feb 2006) | REVISION DRIFT ACROSS TWO DECADES. The 2006 Army TM's Pro-Torq procedure reads 200 lb-ft rotating, back off hand tight, re-torque 100. STEMCO's current chart (Rev 1/20) triples the seating and adjustment cycles and replaces 'hand tight' with counted back-off fractions by thread pitch. Same fastener, same maker, materially tightened procedure — follow the current chart, and treat any shop still working from the old memory as a retraining conversation. |
| Fontaine fifth wheel: mounting hardware, 5/8 in Grade 8 | 90–122 ft-lb (lube condition not stated) | Fontaine Fifth Wheel Installation Guide LT-181 (May 2020 R6) | Covers NWB, LWB and AWB slide mounts, PML plate mount, FMA stationary bracket. First fifth-wheel values in the register — the joint that carries the whole trailer. |
| Fontaine fifth wheel: PS5 heavy-duty plate mount, 3/4-10 Grade 8 | 155–210 ft-lb (lube condition not stated) | Fontaine Fifth Wheel Installation Guide LT-181 (May 2020 R6) |  |
| Bendix ADB22X: caliper/carrier bolts, vertical mount, M16 x 2.0 Class 12.9 | 229 ft-lb (lube condition not stated) | Bendix ADB22X / ADB22X-V / ADB22X-LT Air Disc Brakes SD-23-7541 | Two-stage: pre-torque 40-50 lb-ft in an alternating cross pattern, then final 229 lb-ft (310 N-m). NO washers, and Bendix recommends new fasteners every time — reusing these bolts is off-book. |
| Bendix ADB22X: caliper/carrier bolts, axial mount, M20 x 2.5 Class 10.9 | 375 ft-lb (lube condition not stated) | Bendix ADB22X / ADB22X-V / ADB22X-LT Air Disc Brakes SD-23-7541 | Pre-torque 20-60, final 375 lb-ft (508 N-m), cross pattern, hardened washer minimum 3 mm with OD under 1.5 in. |

| Bendix ADB22X: spring brake chamber mounting nuts | 133 ±7 ft-lb (lube condition not stated) | Bendix ADB22X / ADB22X-V / ADB22X-LT Air Disc Brakes SD-23-7541 | 180 +/-10 N-m. Relevant to every air-disc axle in the register — the finder's Air disc brake answer now has real numbers behind it. |
| Bendix ADB22X: rotor shield cap screws | 44 steer/drive · 24 trailer ft-lb (lube condition not stated) | Bendix ADB22X / ADB22X-V / ADB22X-LT Air Disc Brakes SD-23-7541 |  |
| Bendix ADB22X: spring brake manual release tool | 35 max ft-lb (lube condition not stated) | Bendix ADB22X / ADB22X-V / ADB22X-LT Air Disc Brakes SD-23-7541 | Maximum 35 lb-ft on the release tool, 50 lb-ft absolute maximum releasing torque. A ceiling, not a target — an impact gun on a caging bolt exceeds this instantly. |
| Hendrickson trailer ADB: outboard rotor flange nuts, 5/8 in (twelve) | 220 ±9 ft-lb DRY | Hendrickson T71004, Trailer ADB Hub, Rotor & Caliper Mounting Procedures (Rev H, March 2025) | 300 +/-10 N-m. DO NOT apply anti-seize or additional lubricant — stated on the fastener itself, matching TMC RP 237B's anti-seize prohibition. Hendrickson also recommends against reusing these fasteners. |
| Hendrickson trailer ADB: flanged hub / U-rotor hex screws, 24 mm or 15/16 | 200 ±9 ft-lb DRY | Hendrickson T71004, Trailer ADB Hub, Rotor & Caliper Mounting Procedures (Rev H, March 2025) | 270 +/-10 N-m, no anti-seize. |

Three caliper makes on one suspension family span 140 to 350 ft-lb — identify the caliper before setting the tool, the same location-decides lesson as Volvo's three-value M16. |
| Heil Half/Pack & Odyssey front loader: fork bearing block bolts (four) | 460 ft-lb (lube condition not stated) | Heil Environmental Half/Pack Operation Manual TP1HP-OM-1217, PM chart p.143 | Check at every 200 operating hours (monthly at Heil's stated 8 hr/day duty). FIRST refuse-body value in the register. Heil publishes body PM by OPERATING HOURS, not miles — daily 8, weekly 40, monthly 200, 6-month 1,000, yearly 2,000. |
| Heil Half/Pack: PTO female pilot greasing | see notes | Heil Environmental Half/Pack Operation Manual TP1HP-OM-1217, PM chart p.143 | Greaseable (non-wet-spline) PTOs: pull the pump bolt flange ~2 in off the PTO and grease the female pilot every 200 hours — skipping it can wreck the pump shaft. NOT required on wet-spline PTOs such as Chelsea 890/897. |
| Heil Trailer dry bulk: QUIK-ALIGN pivot connection | 505–595 ft-lb (lube condition not stated) | Heil Trailer International Dry Bulk Vacuum Pneumatic Trailer Owner's Manual (2012), Torque Chart p.71 | 685-807 N-m. Compare Hendrickson 97117-251's 590 for the 7/8 QUIK-ALIGN pivot — Heil's band brackets it. |

| Heil Trailer dry bulk: air spring nuts | 80–100 upper · 40–50 lower HT · 25–35 lower INTRAAX ft-lb (lube condition not stated) | Heil Trailer International Dry Bulk Vacuum Pneumatic Trailer Owner's Manual (2012), Torque Chart p.71 | Upper and lower differ, and the lower value differs by suspension series. Three chances to get one air bag wrong. |
| Heil Trailer dry bulk: brake chamber mounting nut (INTRAAX) | 100–110 ft-lb (lube condition not stated) | Heil Trailer International Dry Bulk Vacuum Pneumatic Trailer Owner's Manual (2012), Torque Chart p.71 | 136-149 N-m. Bendix publishes 133 +/-7 for its chamber nuts — the two bands overlap almost exactly. |

Second inch-pound cluster in the register after the Blue Bird bleed screw — same misread-the-units hazard. |
| Heil Trailer dry bulk: SHEAR-OFF alignment pivot bolts | 550 ±45 (by design) ft-lb (lube condition not stated) | Heil Trailer International Dry Bulk Vacuum Pneumatic Trailer Owner's Manual (2012), Torque Chart p.71, p.65/70 | Torque-by-design: the specially plated Torx-head bolt is driven until the head SHEARS OFF, which is what guarantees the 550 +/-45 clamp (Heil calls it H-45 torque). No wrench setting exists — the fastener is the calibration, and pivot bolts must be REPLACED whenever the trailer is aligned. A different answer to the same problem the cal program solves. |
| Heil Trailer dry bulk: structure and retorque intervals | 150 ft-lb (lube condition not stated) | Heil Trailer International Dry Bulk Vacuum Pneumatic Trailer Owner's Manual (2012), Torque Chart p.71, maintenance schedule | Front and rear structure bolts 150 ft-lb checked WEEKLY, wheel lug torque WEEKLY, suspension bolt torque every 5,000 miles. A dry-bulk tanker's own book asks for more wrench time per month than most fleets give a trailer per year. |
| Heavy-duty stud-piloted largest thread — RESOLVED to 1-5/16-12 | 750–900 ft-lb DRY | TMC RP 237B Table 1 + Heil Trailer Torque Chart p.71 vs PACCAR 01/2026 manuals | UPDATE to the earlier verify flag: Heil Trailer's wheel chart independently prints 15/16-12, 1-1/8-16 and 1-5/16-12 at 750-900 dry, agreeing with TMC. Both PACCAR revisions print 1-15/16-12 — a 49 mm stud, which no disc wheel uses. Two independent publishers plus physical plausibility against one repeated value: the PACCAR tables carry a propagated typo. Order sockets for 1-5/16. |
| McNeilus Bridgemaster V lift axle: cylinder mounting nuts | 254 ft-lb (lube condition not stated) | McNeilus TSB MXR-TSB-029 (Feb 2022), Bridgemaster V model 93 | 3/4-10 Grade 8 cap screws, hardened washers, distorted-thread locknuts — four sets per cylinder end, torque FROM THE NUT SIDE. From a 2022 field campaign: every 2020-21 unit with standard bolts had to be torque-CHECKED, and any fastener not at spec REPLACED, not retorqued (locknuts are one-use). Units built with Huck fasteners were exempt — swaged collars do not lose clamp. |
| McNeilus Bridgemaster V lift axle: cross member nuts | 451 ft-lb (lube condition not stated) | McNeilus TSB MXR-TSB-029 (Feb 2022), Bridgemaster V model 93 | 7/8-14 Grade 9 cap screws, eight sets. Same campaign, same rule: off-spec = replace the hardware. McNeilus paid fleets 2 hours labor just to run the torque wrench over it — an OEM putting a dollar figure on exactly the inspection the cal program sells. |
| McNeilus Bridgemaster V: tandem fender hardware | 13 ft-lb (lube condition not stated) | McNeilus TSB MXR-TSB-029 (Feb 2022), Bridgemaster V model 93 | 15 sets per fender. 13 ft-lb next to 451 ft-lb in the same document — a 35x spread on one axle assembly. |
| Altec LS60: rotation bearing cap screws, outer race | 260 ft-lb (lube condition not stated) | Altec SIL 753 (April 2020) + LS60 Maintenance Manual excerpt | 353 N-m, Grade 8, factory dry-film lubricant with bonded patch-lock threads. Numbered pattern first pass, then a full circular second pass at the same value. Altec's anti-seize list covers pins and splines — NOT these screws; their coating is the specified friction condition. |
| Altec LS60: rotation bearing cap screws, inner race | 300 ft-lb (lube condition not stated) | Altec SIL 753 (April 2020) + LS60 Maintenance Manual excerpt | 407 N-m. MANUFACTURER-CORRECTED ERROR: the maintenance manual shipped stating 365 ft-lb on p.24; SIL 753 corrects it to 300 and required owners to physically replace the manual page within 30 days. A 65 ft-lb overtorque on a slew-ring fastener, caught by the maker — the strongest revisions-matter artifact in the register. Note the pattern quirk: there is no cap screw in inner-race position 1 (the gearbox sits there); torquing starts at 2. |
| Altec LS60: rotation gearbox mounting cap screws | 150 ft-lb (lube condition not stated) | Altec SIL 753 (April 2020) + LS60 Maintenance Manual excerpt | 203 N-m, Altec-supplied special cap screws and washers only. Broken or missing screw = replace ALL fasteners in that race. |
| Altec LS60: annual rotation-bearing torque inspection | 90% of installation torque ft-lb (lube condition not stated) | Altec SIL 753 (April 2020) + LS60 Maintenance Manual excerpt | Check annually with a calibrated CLICK-type wrench set to 90% of installation value, smooth pull, no jerking; any screw that turns before the click means retorque the entire race. Interesting split: TMC RP 237B forbids clickers for measuring REMAINING torque, while Altec specifies one for a pass/fail threshold check — different question, different tool. A documented annual torque inspection on every utility fleet's aerial devices is the cal program's beachhead into Linetec-class accounts. |
| Ridewell RAR-266 air-ride: shear-type pivot bolt | see notes | Ridewell RAR-266 Trailer Air-Ride ISM (266-Trailer-ISM Rev P, 04-22-2026), torque specifications | Torque-by-design, not a wrench setting. A 1" impact drives the Torx head until it SHEARS OFF (E-20 Torx socket); do not lubricate the threads and do not re-torque after install — replace if damaged. Same principle as Heil's H-45 alignment bolt and McNeilus Huck fasteners: the fastener is the calibration. This is the pivot on essentially the entire Hicks Manufacturing line. |
| Ridewell RAR-266 air-ride: shock absorber locknut | 200–230 ft-lb (lube condition not stated) | Ridewell RAR-266 Trailer Air-Ride ISM (266-Trailer-ISM Rev P, 04-22-2026), torque specifications | 271-312 N-m, 3/4-10NC, lubricated threads (1-1/8" hex). The heaviest wrench setting on the RAR-266 — a battery clicker or VT-1000 with a deep 1-1/8" socket covers it. |
| Ridewell RAR-266 air-ride: air spring upper locknut | 45–50 ft-lb (lube condition not stated) | Ridewell RAR-266 Trailer Air-Ride ISM (266-Trailer-ISM Rev P, 04-22-2026), torque specifications | 61-68 N-m, 3/4-16NF, pre-lubricated (1-1/8" hex). |
| Ridewell RAR-266 air-ride: air spring lower nut / lock washer | 45–50 overslung · 20–25 low-mount ft-lb (lube condition not stated) | Ridewell RAR-266 Trailer Air-Ride ISM (266-Trailer-ISM Rev P, 04-22-2026), torque specifications | 1/2-13NC. 45-50 ft-lb (61-68 N-m) on 23K/25K/30K overslung locknuts; 20-25 ft-lb (27-34 N-m) on 20K/25K low-mount lock washers. Same thread, two different numbers by mount — a get-it-wrong hazard. |
| Ridewell RAR-266 air-ride: initial re-torque interval | see notes | Ridewell RAR-266 Trailer Air-Ride ISM (266-Trailer-ISM Rev P, 04-22-2026), torque specifications | Fasteners ship at minimal torque and must be brought to spec, then re-torqued after the first 6,000 miles or the warranty is void. A documented re-torque call-out on air-ride running gear — the retorque/cal-log angle. |
| Hicks Manufacturing line — running-gear fitment | see notes | Hicks model spec tables (hickstrailers.com) + Ridewell RAR-266 ISM | 12 of 13 published Hicks models ride Ridewell RAR-266 air-ride; the All-American Quad rides RAR-239. Wheel end is uniform 8.25x24.5 hub-piloted on 11R24.5 (33 mm flange nuts — KIT-WE-1), and every model runs an 8" trunnion-mount hoist (KIT-HC-1). Bodies are weld-free Huck-bolted aluminum, so the torque work is the running gear, not the frame. One WE-1 + the RAR-266 suspension numbers + HC-1 map onto the whole catalog. |
| Watson & Chalin single-point: 5/8" U-bolt nut (Grade 8) | 120–150 ft-lb LUBRICATED | Watson & Chalin Single Point Suspension catalog (SP-0095) — torque table, W&C Installation & Operation Manual WC136 (Rev 05-03-2011) | 163–203 N-m, 5/8" Grade 8 UNF, clean LUBRICATED thread — Watson & Chalin's published single-point value. NOTE: Clement's own single-point is STAR Heavy Duty, not W&C — see the STAR Heavy Duty rows for the values that are actually on a Clement trailer. |
| Watson & Chalin single-point: 3/4" U-bolt nut (Grade 8) | 200–250 ft-lb LUBRICATED | Watson & Chalin Single Point Suspension catalog (SP-0095) — torque table, W&C Installation & Operation Manual WC136 (Rev 05-03-2011) | 271–339 N-m, 3/4" Grade 8 UNF, clean lubricated thread. The next U-bolt size up in the W&C single-point table if a heavier axle seat is specified (1-1/8" socket). |
| Watson & Chalin single-point: bracket / equalizer capscrew (5/8" Grade 8) | 150–200 ft-lb (lube condition not stated) | Watson & Chalin Single Point Suspension catalog (SP-0095) — torque table, W&C Installation & Operation Manual WC136 (Rev 05-03-2011) | 203–271 N-m, 5/8" Grade 8 UNF. Mounting/bracket hardware on the W&C single-point; the catalog table does not label these lubricated, so treat the band as-published (15/16" socket). |
| Watson & Chalin single-point: bracket / equalizer capscrew (3/4" Grade 8) | 300–350 ft-lb (lube condition not stated) | Watson & Chalin Single Point Suspension catalog (SP-0095) — torque table, W&C Installation & Operation Manual WC136 (Rev 05-03-2011) | 407–475 N-m, 3/4" Grade 8 UNF. Heaviest bracket capscrew on the single-point (1-1/8" socket). |
| Watson & Chalin single-point: 3/4" stabilizer shock stud | 150–175 ft-lb (lube condition not stated) | Watson & Chalin Single Point Suspension catalog (SP-0095) — torque table, W&C Installation & Operation Manual WC136 (Rev 05-03-2011) | 203–237 N-m, 3/4" shock-mount stud on the W&C single-point stabilizer (1-1/8" socket). |
| Watson & Chalin single-point: re-torque interval | see notes | Watson & Chalin Single Point Suspension catalog (SP-0095) — torque table, W&C Installation & Operation Manual WC136 (Rev 05-03-2011) | W&C calls for a re-torque of the suspension fasteners after the first 30 days in service, then every 6 months thereafter — the documented retorque/cal-log call-out on the single-point running gear. |
| Clement Industries single-point line — suspension fitment | see notes | Clement model spec tables (clementind.com) + STAR Heavy Duty decal STAR-SPT-50-102 — Clement's own single-point suspension | Clement's 50,000-lb single-point models ride a STAR Heavy Duty single-point suspension — STAR is Clement's OWN suspension brand (Sibley LA), and the torque decal STAR-SPT-50-102 ships on every trailer. Values: 1-1/8" trunnion U-bolt 670 lubricated / 880 dry, 3/4" pedestal 220/300, 5/8" axle U-bolt & end cap 130/180. (Corrects the earlier Watson & Chalin assumption.) Air-ride models ride Ridewell RAR-266. Wheel end is uniform 8.25x24.5 hub-piloted on 11R24.5 (33 mm — KIT-WE-1); 8" trunnion-mount hoist (KIT-HC-1); AXN parallel-spindle axles. TOOL: the 880 trunnion needs a VT-2000/VTR-1000; the 130–300 U-bolts, pedestal & end caps are a VTR-750 job — two tools, matched to the joints. |
| STAR Heavy Duty single-point: 1-1/8"-12 trunnion U-bolt | 670 lubricated · 880 dry ft-lb | STAR Heavy Duty (Clement Industries) Single Point Suspension Torque Requirements decal STAR-SPT-50-102, Sibley LA | 908 N-m lubricated / 1193 N-m dry. The primary single-point attachment. Use the LUBRICATED value on lightly oiled threads, the DRY value on dry threads (per the STAR decal). THIS IS THE HEAVY JOINT — a VT-2000 or VTR-1000 (1" drive), NOT the VTR-750, which tops out at 750. This is what Clement's single-point trailers actually run; STAR Heavy Duty is Clement's own suspension brand. |
| STAR Heavy Duty single-point: 3/4"-16 pedestal nut | 220 lubricated · 300 dry ft-lb | STAR Heavy Duty (Clement Industries) Single Point Suspension Torque Requirements decal STAR-SPT-50-102, Sibley LA | 298 N-m lubricated / 407 N-m dry. Pedestal-to-frame. A VTR-750 covers it (1-1/8" socket). |
| STAR Heavy Duty single-point: 5/8"-18 axle U-bolt | 130 lubricated · 180 dry ft-lb | STAR Heavy Duty (Clement Industries) Single Point Suspension Torque Requirements decal STAR-SPT-50-102, Sibley LA | 176 N-m lubricated / 244 N-m dry. Clamps the axle to the beam. VTR-750 (15/16" socket). |
| STAR Heavy Duty single-point: 5/8"-18 end cap nut | 130 lubricated · 180 dry ft-lb | STAR Heavy Duty (Clement Industries) Single Point Suspension Torque Requirements decal STAR-SPT-50-102, Sibley LA | Same 130/180 as the axle U-bolt (176/244 N-m). VTR-750. |
| STAR Heavy Duty single-point: re-torque interval | see notes | STAR Heavy Duty (Clement Industries) Single Point Suspension Torque Requirements decal STAR-SPT-50-102, Sibley LA | STAR calls for ALL fasteners to be checked after the ~1,000-mile break-in, then at least every 4 months thereafter — failure to follow can void the warranty. Different clock than the wheel-ends (TMC RP 237B: 50–100 mi then every 10,000 mi), so a Clement trailer runs TWO re-torque schedules — suspension on a calendar, wheel-ends on mileage. |
| Waltco HLF liftgate: 3/4" mount plate to truck chassis | 250–300 ft-lb (lube condition not stated) | Waltco HLF Series Liftgate Installation Manual (80122701, Rev 14), torque specifications | 339–407 N-m. Galvanized mount plate to frame — the primary liftgate-to-chassis joint. Lube not stated in the manual; 1-1/8" socket. |

| Hiab loader crane: slew-ring / king-post / subframe mounting torque | see notes | Hiab loader-crane installation / FrameWorks & BodyWorks mounting instructions (dealer/installer program) | The structural crane-mounting torques (slewing ring, king-post base, subframe-to-chassis) live in Hiab's installation / FrameWorks & BodyWorks installer program, not in public operator manuals. Dealer/installer access only — a real gap for upfitters, and the pitch for the register. |
