1986 John Deere 710B Backhoe Loader Technical Manual (P/N TM-1286)

• Factory publication and coverage: John Deere TM-1286 (Dec-86), a 1,356-page PDF for the John Deere 710B Backhoe Loader.
• Engine work: Covers engine removal with or without the transmission and reverser, plus crankshaft, camshaft and timing gear train, piston and liner, cylinder head and valve, turbocharger, water pump, fuel-system bleeding, and injection-pump timing procedures.
• Power train and axle repair: Details transmission removal; C1/C2 clutch-pack, planetary, reduction-gear, control-valve, and modulator work; MFWD transfer-case service; differential setup; and both powered and non-powered front axle procedures.
• Hydraulic, steering, and brake service: Documents main pump and stroke-control valve overhaul, steering valve and cylinder repair, brake valve and accumulator work, brake bleeding, and factory pressure, flow, leakage, relief-valve, and cycle-time tests.
• Loader and backhoe systems: Separates Gresen and Cessna loader valves, return-to-dig and non-return-to-dig bucket sections, two-, three-, and four-lever backhoe controls, the extendible dipperstick, and service for boom, swing, bucket, crowd, and stabilizer components.
• Electrical diagnosis and system testing: Provides starting, charging, lighting, warning, and accessory-circuit tests; tachometer calibration; operational checkout; engine performance checks; complete transmission and drag tests; wiring diagrams; and hydraulic schematics.

Factory Repair Coverage

John Deere states that this technical manual was planned and written for an experienced service technician. Its on-the-job format assumes safe heavy-component handling, hydraulic test equipment, electrical meters, and normal shop practice rather than teaching basic theory. Each service group opens with the applicable specifications, wear tolerances, torque values, essential tools, and materials before moving into illustrated teardown, inspection, assembly, adjustment, and final-check coverage.

The manual identifies the machine's 329-cu.-in. six-cylinder turbocharged diesel, full power shift transmission with eight forward and four reverse speeds, hydraulic wet-disc service brakes, and hydrostatic power steering. Reference data includes lubrication schedules, fluid capacities, component-specific torque tables, clearances, bearing preload and end play, wear limits, electrical test values, and hydraulic pressure and flow specifications.

Configuration and Serial-Specific Detail

Separate chapters distinguish MFWD from non-powered front-axle machines, including the MFWD axle, constant-velocity joints, transfer case, clutch valve, and steering cylinder. Cab and ROPS removal procedures are also separate. Loader repair information accounts for both Gresen and Cessna control valves and bucket sections with or without return-to-dig. Backhoe coverage recognizes two-lever and three- or four-lever control arrangements, along with standard and extendible dipperstick components.

The service-brake chapter identifies riveted pressure plates through serial number 701416 and bonded plates from 701417 onward; it also states that the bonded type is used as the replacement part on earlier units. The operator-station section covers cab glass, wipers, heater motor and core, and the heater-valve switch. Although the group is titled "Heating and Air Conditioning," it does not provide refrigerant-circuit, compressor, condenser, or evaporator service procedures.

Testing, Diagrams, and Shop Equipment

Section 90 supplies structured fault isolation for the engine, electrical system, power train, main hydraulics, steering, brakes, differential lock, and transmission hydraulics. Named procedures include main-pump flow and standby-pressure testing, steering and component leakage checks, MFWD clutch-pressure testing, brake-accumulator precharge testing, transmission pump-flow and lube-pressure testing, and a recorded complete transmission test.

Reference graphics include the Electrical Schematics and Electrical Wiring Diagrams, Power Flow Through Transmission, Transmission Hydraulic System Schematic, Main Hydraulic System Schematic, the MFWD steering-cylinder exploded view, and Gresen/Cessna loader-control-valve cross sections. Service-Gard tool listings identify equipment by number, including the D-01080AA Hydraulic Analyzer, D-15051NU Flow Meter, D-27001TX Hydraulic Cylinder Servicer, D-27501BM digital volt-ohm-amp meter, and JT01642 Low-Lift Transmission Jack.

Scope Limits and Service Cautions

The manual covers fuel-injection pump removal, installation, timing, and system bleeding, but directs internal pump repair to John Deere SM-2045. It likewise covers nozzle removal and installation while referring nozzle repair to TM-7214.

The transmission installation section warns against using the case cap screws to draw the transmission against the flywheel housing when the input shaft and pilot bearing are not aligned, since transmission damage can result. Backhoe-cylinder assembly coverage also flags nicks or burrs on piston lands and barrel chamfers, as well as rod-to-barrel misalignment, because these conditions can cut the cap seals.

Before opening hydraulic lines or working around raised loader or backhoe structures, follow the manual's safety and blocking procedures, relieve stored pressure, and use lifting equipment rated for the component.
