John Deere 310E Backhoe Loader Repair Manual, 1997–2002 (P/N TM1649)

John Deere Technical Manual P/N TM1649, 22JUL10 (English), is the factory repair publication for the 310E Backhoe Loader. Its 18 numbered sections cover machine-level removal, disassembly, inspection, assembly, adjustment, and repair.

PDF Search, Illustration Detail, and Page Count

Search and drawing access: PDF text search and embedded bookmarks are not available. Small labels in the cab, engine, auxiliary-flow, and ride-control electrical views are readable with zoom. Several other illustration pages show a title but no drawing, including the heater/blower assembly diagrams; their embedded thumbnails do not provide readable diagram detail.

One printable PDF in English contains 1,081 pages, including six opening pages: the cover, contents, a two-page foreword, and a two-page publication-feedback form.

Transmission, Hydraulic, and Backhoe Repair Coverage

The selected topics below outline major workshop content rather than the complete contents. Other covered work includes radio and back-up alarm service.

• Transmission: Removal and step-by-step clutch-pack, synchronizer, shaft, control-valve, charge-pump, and transmission-case repair.

• Axles, brakes, and steering: Rear-axle overhaul, planetary and differential service, park and service brakes, brake bleeding, steering-valve and cylinder repair, and front-axle alignment.

• Hydraulic components: Main pump, reservoir and coolers, loader/backhoe control valves, relief and anti-cavitation valves, ride-control accumulators, and 120- and 125-series cylinder repair.

• Loader and backhoe structures: Loader removal, bucket and cutting-edge repair, multi-purpose bucket service, self-leveling and return-to-dig adjustment, boom, dipperstick, swing-frame, stabilizer, and extendible-dipperstick work.

• Engine and auxiliary systems: Engine removal and installation, cold-starting aid, cooling-system service, air-intake leakage testing, exhaust, and fuel-tank work.

• Electrical service: Battery testing, harness and fuse service, Kostal, DEUTSCH, and WEATHER PACK connector repair, plus electrical component-location views.

• Cab and air conditioning: Cab/ROPS, seat, window, hood, grille, and fender repair; R134a recovery, evacuation, charging, leak testing, and compressor service.

Written for experienced technicians, the manual identifies essential tools for particular service jobs and assumes familiarity with basic service theory.

Configurations and Companion Test Information

Coverage distinguishes 4045D naturally aspirated and 4045T altitude-compensated engine installations, non-powered front axles and APL-2025 MFWD, standard and extendible dippersticks, and ROPS or cab equipment. Optional ride control, auxiliary flow, and the multi-purpose loader bucket have their own repair information.

Serial-specific rear-axle data, upper rear-window parts, crowd-cylinder piston-nut specifications, and stabilizer-linkage procedures help match the instructions and component details to the machine before disassembly.

Diagnosis scope: This is the repair half of the factory service information. The separate TM1648 Operation and Test publication is referenced for machine diagnosis, transmission pressure tests, service-brake leakage tests, and certain hydraulic relief-valve adjustments; it is not included.

Transmission and Rear-Axle Overhaul

Transmission coverage extends to the converter side of the case, input drive shaft, intermediate and rear output shafts, MFWD output shaft, idler shaft, and manifold-plate solenoids. The manual distinguishes the forward and reverse clutch packs and their original bores. Clutch-pack instructions warn that installing outer bearings with the gear hub incompletely engaged can damage the disks. The torque converter is a removal-and-replacement assembly with no internal service parts.

Rear-axle setup includes pinion-depth calculations, shim selection, bearing rolling drag, backlash, gear-tooth contact checks, differential-lock work, and final service-brake checks. Ring gear and pinion are treated as a matched assembly.

The non-powered and MFWD front-axle sections provide toe-in procedures; MFWD steering coverage also includes tracking-angle adjustment. Internal APL-2025 axle repair requires the separate CTM4509, while steering-cylinder repair is covered here.

Control Valves, Accumulators, and Cylinder Seals

Separate repair sections distinguish earlier and later flow-control relief valves and the individual loader and backhoe valve sections. Spools must retain their original section and installation orientation for the hydraulic functions to operate correctly.

Ride-control charging procedures distinguish the accumulator designs. Cylinder instructions cover seal orientation and indexing as well as assembly: misaligned cylinder parts or nicked piston lands can cut the cap seals.

Engine, Electrical, and Cab Service

The engine section covers removal and installation; internal PowerTech 4045 engine work requires CTM104. Auxiliary-system coverage includes radiator, fan and belt service, coolant-heater and starting-aid components, intake sealing, and exhaust arrangements with or without altitude compensation.

Electrical harness and component views cover the cab roof, consoles, engine, blower, A/C compressor, auxiliary-flow system, and ride-control system. Complete Bosch alternator and starting-motor repair requires CTM77.

Cab work includes windows, wipers, latches, seat mechanisms, and suspension. A/C procedures include compressor clutch and seal service and component-specific oil-charge data. The compressor’s valve plates, reed valves, cylinders, and cylinder housings are not serviceable.

Factory Tools and Component Views

Tool references include the JDG1056 axle spanner nut wrench, JDG1057 MFWD shaft-seal installer, JDG393 engine lifting bracket, JDG140 METRIMATE extractor, JDG1290 relief-valve seal installer, and JDG734 spool-valve seal installation tool.

Dealer-fabricated drawings cover transmission supports, rear-axle mounting and rolling-torque fixtures, the cab/ROPS lift bracket, and the compressor holding fixture. The A/C section identifies R134a recovery, recycling, and charging equipment.

Illustration examples include the Rear Output Shaft Cross Section View, MFWD Shaft Cross Section View, Park Brake Cross Section, Cross Section of Steering Valve, Cab Roof Harness–Components, and Backhoe Hydraulic-Component Location. Supporting references include component torque tables, fluid capacities, ambient-temperature viscosity data, lift-capacity charts, wear limits, and clearances.

Workshop safety: Raised loader and backhoe structures, stored hydraulic or accumulator pressure, heavy driveline components, tires, batteries, welding, and refrigerant work carry machine-specific safety procedures. Follow the complete OEM procedure with the specified supports, boom lock, tools, and training.

Clutch Clearance and Axle Backlash: A Preview

The transmission clutch-pack section specifies plate clearance of 2.5–3.2 mm (0.098–0.126 in.) during assembly inspection.

Rear-axle setup data specifies ring-gear backlash of 0.15–0.25 mm (0.006–0.010 in.), alongside the shim calculations and contact-pattern checks used to assess gear alignment.
