John Deere Compact Excavator & Tractor Torque Specs

Quick-reference torque specifications for John Deere G-series compact excavators (17G–50G) and 1025R/2025R compact utility tractors. Always cross-check with the machine-specific service manual before beginning any fastener work — specs can vary by serial-number range and model year. For the full 1-, 2-, and 3-Series tractor family (1023E, 1026R, 2032R, 2038R, 3025E–3046R) with complete serial-number breakdowns, see John Deere Compact Tractor Torque Specs.

Quick-reference torque specs

Wheel Bolt — 1023E (serial 010001–, pre-HJ100001) 120 N·m (89 lb-ft) (Confirmed identical, front and rear, across three North American 1023E Operator's Manual serial ranges (010001-209999, 210000-309999, and 310001- in the combined manual it shares with the early 1025R). Superseded at the HJ100001 serial break — see the 1023E/1025R HJ100001 row below.)

Wheel Bolt — 1026R (serial 010001–309999) 120 N·m (89 lb-ft) (Confirmed for the two 1026R serial ranges published alongside the 1023E (010001-209999 and 210000-309999). No later 1026R-specific manual was found — 1026R does not appear in the 310001-/HJ100001- combined manuals' titles, so no claim is made about it past serial 309999; do not assume it follows the 1023E's later serial break.)

Wheel Bolt — 1025R (serial 110001– , pre-HJ100001) 120 N·m (89 lb-ft) (Earlier-generation 1025R Base Unit serial range, per the combined 1023E(310001-)/1025R(110001-) manual dated September 2013.

Wheel Bolt — 1023E / 1025R (serial HJ100001–current / Cab serial KK400001–current) 95 N·m (70 lb-ft) (Serial-number break, revised 2017-02-02, confirmed still current in the newest RS000001-/MY2025 edition. Front and rear are identical. This is a LOWER torque than the earlier serial ranges above for BOTH models — check your tractor's serial number plate before torquing; do not assume which spec applies by model year alone. CORRECTED 2026-09: this manual (OMTR110056) is explicitly titled for 1023E (HJ100001-) AND 1025R (HJ100001-)/1025R Cab (KK400001-) together, with one shared, undifferentiated "Wheel Bolt Torque" spec — the 1023E DOES share this later figure; a prior version of this row said it didn't.)

Sequence-required & verify-against-manual fasteners

These structural or safety-critical fasteners require the machine-specific tightening sequence or a service-manual value rather than a single number: Swing Bearing (Slewing Ring) Bolts — G-series compact excavators — See sequence (Torque and cross-pattern tightening sequence are machine-specific and bolt-grade-dependent; refer to TM12894 (35G) or equivalent section on Swing or Pivoting System (Section 43). Structural fastener — always use service manual.) Source: JD TM12894 35G Technical Manual table of contents confirms Section 43 Swing or Pivoting System; specific torque is grade/size-dependent per Group 0003 metric bolt tables.. Counterweight Bolts — G-series compact excavators — See sequence (Counterweight removal/installation procedure is in TM12894 Section 17 Group 1749. Torque and sequence depend on bolt size and grade; consult Group 0003 torque tables in the service manual.) Source: JD TM12894 35G Technical Manual table of contents, Section 17 Group 1749 'Chassis Weights — Counterweight Remove and Install'.. Final Drive / Travel Motor Mounting Bolts — G-series compact excavators — See service manual (Travel motor and park brake fastener torques are covered in TM12894 Section 02 Group 0260. Bolt sizes vary between 17G, 26G, 35G, and 50G — use the model-specific manual.) Source: JD TM12894 35G Technical Manual table of contents, Section 02 Group 0260 'Travel Motor and Park Brake Disassemble and Assemble'.. Engine Oil Drain Plug — Yanmar 3TNV88 (35G) M22 — See service manual (Drain plug part no. 119640-01640; always replace seal washer 22190-220002 (22 mm). Yanmar 3TNV88 service documentation does not publish a specific ft-lb figure for the drain plug; tighten until seal washer is compressed. Check engine-specific Yanmar service manual for any updated guidance.)

ROPS / Loader Frame Mounting Bolts — 1025R/2025R tractors — See service manual (Structural/safety-critical fasteners. Torque values are in the John Deere 1025R/2025R Technical Manual. Do not substitute generic grade-5 or grade-8 values without confirming bolt size and grade from the service manual.)
