New Holland LW110/LW130 (W110/W130) Wheel Loader Service Manual, 1999 (P/N 75131007)

This March 1999 factory service manual (P/N 75131007) covers New Holland LW110 and LW130 wheel loaders. The technical sections use the W110 and W130 designations.

PDF Search, Bookmarks, and Page Contents

Text search and diagram detail: Embedded OCR supports partial text search. Some pages, diagram labels, and table entries are outside the searchable text, and recognition errors can prevent matches. Bookmarks cover all eight service sections. The Home Page bookmark points to a separate file. Small wire codes and connector pin labels in the wiring diagrams are easier to read when zoomed in.

The download contains one printable, English-language 334-page PDF. It includes 18 preliminary pages, including the cover, 315 pages across the eight service sections, and one copyright page. The service-section count includes the section contents pages and a repeated transmission delivery-filter page.

Powershift Repair, Hydraulic Testing, and Wiring

The highlights below are selected topics from the manual. Other examples include cold-start preheating fault indications and prop shaft drawings.

• Engine reference: Specifications, mounting clearances, injection-pump calibration tables, turbocharger data, and cooling and lubrication system descriptions.
• Transmission and axles: Powershift and torque converter disassembly and reassembly, clutch service, torque-proportioning differentials, and planetary final drives.
• Brake service: Pressure tests, accumulator precharge checks and resetting, brake bleeding, parking-brake diagnosis, and disc-wear inspection.
• Steering: Orbitrol valve overhaul, steering-cylinder service, priority-valve operation, and optional emergency-steering components.
• Loader hydraulics: Equipment pump inspection, mechanical and pilot-operated control valves, bucket automatic leveler, optional boom kickout, and optional L.T.S. testing.
• Electrical systems: Wiring diagrams, connector views, logic-board connections, instrument circuits, and ATC automatic-transmission controls.
• Cab repair: Cab removal and installation, bonded safety-glass replacement, heater components, and windshield wiper and washer systems.

The manual is suited to experienced equipment mechanics with the lifting equipment, presses, and hydraulic test instruments used for drivetrain and hydraulic work.

Engine Clearances and Injection-Pump Settings

Separate calibration tables cover the Bosch VE6/12 F 1150 RV injection pump on the W110 and the VE6/12 F 1100 RV on the W130. Mounting-clearance tables cover pistons, crankshaft bearings, and valvetrain components. The lubrication section describes forced circulation with full-flow and bypass filtration. Torque tables, fluid capacities, and dimensional drawings provide additional reference data.

Engine scope: The engine chapter provides specifications, calibration data, and system descriptions. For a complete internal engine overhaul, a separate reference is needed. The printed pagination jumps from 1-9 to 1-11.

TCM Powershift Transmission and Axle Repair

Powertrain diagrams, clutch-engagement pressure diagrams, and symptom-based troubleshooting help mechanics distinguish a shift-control fault from an internal clutch problem when a loader loses travel in one direction or gear. The control-valve section identifies contamination from wiping materials and sealing tape as a cause of blocked oil passages and hydraulic malfunction.

Axle service covers crown wheel backlash, tooth-contact patterns, and axle-bearing preload. The drawings and adjustment data support inspection and reassembly of the differentials and final drives.

Brake Testing and Orbitrol Steering

Brake hydraulic schematics identify connections used for service-brake and accumulator pressure checks. The nitrogen precharge procedures illustrate test tool 75298472.

Orbitrol overhaul includes exploded views, rotor-to-shaft alignment references, and a note on adapting a socket wrench for spring installation. The steering section explains the standard load-sensing circuit and the optional emergency-steering circuit with its secondary priority valve.

Bucket Controls, Equipment Hydraulics, and L.T.S.

Separate hydraulic diagrams identify the KVS-120H-3MD mechanical control valve and the KVS-120H-3 pilot-operated variant. The equipment and steering pump section gives component wear criteria. Cylinder drawings identify boom and bucket components.

Boom, bellcrank, and frame-pivot drawings accompany the bucket leveler and optional boom kickout coverage. The manual also documents optional auxiliary hydraulics and includes electrical, functional, and accumulator tests for the L.T.S. anti-pitching system.

Electrical Fault Tracing and Cab Service

Connector A–D views identify wire numbers and colors across the cab, front-frame, and rear-frame harnesses. The instrument and switch-panel diagram and ATC connector assignments help trace gearshift, sensor, and warning-lamp circuits.

The bonded-glass section covers corrosion protection where adhesive removal damages paint and gives curing restrictions for the new bond.

Follow standard workshop safety precautions and wear appropriate personal protective equipment, with particular attention to raised booms, heavy components, and stored hydraulic pressure.

Selected Coolant Capacity and Clutch and Brake Wear Limits

The fluid-capacity table lists 28 liters of coolant for both models. The transmission maintenance table lists a standard clutch-disc thickness of 2.12–2.28 mm and a 1.9 mm service limit.

For the front and rear axle brake discs, the wear-check section gives replacement thresholds below 5.3 mm for the W110 and below 6.3 mm for the W130.
