2000 New Holland LM840, LM850 & LM860 Telehandler Service Manual

This New Holland service manual covers the 2000 LM840, LM850, and LM860 telehandlers. The March 2000 material comprises six service sections for the transmission, front and rear axles, brakes, steering, and telescopic boom.

Text search and diagram detail: The manual text is searchable, with PDF bookmarks for all six service sections. Small labels in the hydraulic schematics are readable when enlarged.

• Transmission and bevel gearbox: Removal, disassembly, clutch-pack repair, synchromesh gear-train service, shaft shimming, torque-converter stall testing, and hydraulic and solenoid checks.

• Front and rear axles: Planetary hub and differential overhaul, bevel pinion depth and swivel-pin preload calculations, crown gear backlash adjustment, and troubleshooting.

• Wet multi-disc brakes: Brake servo inspection, axle brake repair, circuit bleeding, accumulator pressure testing, brake-disc wear checks, and parking brake adjustment.

• Hydrostatic steering: Steering control valve, motor, and cylinder overhaul, load-sensing flow divider operation, steering-mode schematics, and pressure testing.

• Telescopic boom: Wear pad replacement and shimming, removal of inner, intermediate, and base sections, and access differences between the covered models.

Suited to mechanics experienced in drivetrain and hydraulic repair, with access to a press, bearing tools, dial indicators, and pressure-test equipment.

Transmission and Bevel Gearbox Repair

The transmission section, with cover reference 86609405, covers the Dana Spicer/Turner Compact Phase 1, T4-2012 unit, including its shafts, synchronizers, rear-drive transfer box, and directional control valve. The stall-test table separates the naturally aspirated LM840 from the turbocharged LM840, LM850, and LM860 group.

The Diagnosis Guide links symptoms to probable causes and corrective actions. Together with the pressure-port layout, it helps separate clutch-circuit, converter, and mechanical faults before transmission teardown.

The torque converter is a sealed, welded unit; coverage is limited to stall testing, cleaning, inspection, and replacement. Reference data include oil-cooler flow tests, lubrication and clutch pressures, solenoid resistance, endplay limits, fluid capacities, and component torque tables.

The Transmission Oil Flow and Directional Control Valve Operation schematic supports circuit tracing. Exploded component views include 90° Bevel Gearbox Component Detail, plus transmission, torque converter, and transfer box assemblies. Tools identified include clutch spring compressor NH01251 and yoke holding tool NH01259.

Axle Identification and Overhaul

Clark-Hurth front axle identification separates 277/160 for LM840/LM850 from 277/161 for LM860; the rear axle is 279/306. Rear-axle overhaul refers to the front-axle procedures, with the parking brake mechanism confined to the front axle.

Pinion depth and preload work calls out tools NH01397 and NH01396. The rear-axle chapter also identifies the oval pivot bushing used for the axle load sensor on European units.

Brake Servo and Steering Hydraulics

The Brake System Schematic and Brake Pipe and Component Layout accompany the servo and wet-brake procedures. Incorrect brake fluid can damage axle seals and hoses, a repair issue addressed in the troubleshooting chart. The parking-brake instructions also warn that excessive lever adjustment stretches the cable.

Steering coverage identifies the Danfoss OSPC LS motor and Ultra 1PX285 pump for LM840/LM850 versus Ultra 2PRO41 for LM860. The Steering Valve Schematic and Flow Divider Valve Operation drawings explain front-wheel, all-wheel, and crab steering and the priority supply shared by steering and brakes.

Boom Configurations and Coverage Limits

LM840/LM850 have three boom sections; LM860 has four. The LM860 has additional rear wear-pad access restrictions, and the procedures distinguish its upper telescoping-cylinder arrangement from the lower arrangement on the other two models.

The boom chapter refers cylinder removal to Section 35, which is not included. Engine repair and complete machine wiring diagrams are also outside this six-section file's scope.

Safety Notice: Follow the manual's complete specifications and safety precautions for hydraulic testing, supported boom work, and heavy-component handling.

PDF Contents and Included Pages

One printable English-language PDF contains 204 pages in total: 196 pages across the six service sections, seven manual cover/introduction/safety pages, and one cover page. The section total already includes six section covers and the blank rear-axle page.
