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

Factory service publication 75131007, March 1999 edition, for New Holland LW110 and LW130 wheel loaders, with W110 and W130 designations used throughout the technical sections.

• 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, 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.

Suited to experienced equipment mechanics with the lifting equipment, presses, and hydraulic test instruments needed for drivetrain and hydraulic repair.

Engine Specifications and Injection-Pump Settings

The engine reference distinguishes the Fiat 8065.25.290 in the W110 from the 8065.25.291 in the W130. Separate calibration tables cover their Bosch VE6/12 F 1150 RV and VE6/12 F 1100 RV injection pumps.

Mounting-clearance tables address pistons, crankshaft bearings, and valvetrain components. System descriptions explain turbocharging, cooling, and forced-circulation lubrication with full-flow and bypass filtration. Tightening-torque tables, fluid capacities, and dimensional drawings provide additional reference data.

Engine scope: This section provides specifications, calibration data, and system descriptions; it does not contain a complete step-by-step internal engine overhaul procedure. Its printed pagination jumps from 1-9 to 1-11.

TCM Powershift Transmission and Axle Repair

Separate TCM 641-25 (W110) and TCM 642-25 (W130) details accompany the transmission teardown and assembly procedures. Axle work includes crown wheel backlash adjustment, tooth-contact checks, and axle-bearing preload adjustment.

Power train diagrams, clutch-engagement pressure charts, and symptom-based troubleshooting help distinguish clutch-control faults from internal mechanical problems when a loader will not travel.

The control-valve instructions identify lint and sealing-tape debris as causes of blocked oil passages and hydraulic malfunction.

Brake Testing and Orbitrol Steering

Brake-system hydraulic schematics identify the connections used for service-brake and accumulator pressure checks. Nitrogen precharge procedures illustrate test tool 75298472, alongside parking-brake diagnostics and brake-system bleeding instructions.

Orbitrol repair includes rotor-to-shaft timing references and exploded assembly views. The steering section distinguishes the standard load-sensing arrangement from the optional emergency-steering system with its secondary priority valve.

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

Separate hydraulic diagrams distinguish the KVS-120H-3MD mechanical control valve from the KVS-120H-3 pilot-operated variant. Equipment/steering-pump inspection includes component wear criteria, while cylinder drawings identify boom and bucket components.

Boom, bellcrank, and frame-pivot drawings accompany explanations of the bucket automatic leveler and optional boom kickout proximity-switch controls. Optional auxiliary hydraulics are also documented. The L.T.S. anti-pitching hydraulic diagram is supported by electrical, functional, and accumulator tests.

Electrical Fault Tracing and Cab Service

Connector A–D views map wire numbers and colors between the cab, front-frame, and rear-frame harnesses. The instrument and switch-panel diagram and ATC connector assignments support tracing gearshift, sensor, and warning-lamp circuits.

Cab procedures cover removal and reinstallation as well as bonded glass replacement. The glass section addresses corrosion protection where adhesive removal damages paint and explains curing restrictions that protect the new adhesive bond.

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

A Preview of Cooling Capacity and Drivetrain Wear Limits

These examples are a small selection of the manual’s capacity and wear specifications. Cooling-system capacity is 28 liters for both models.

For both transmissions, clutch-disc standard thickness is 2.12–2.28 mm, with a 1.9 mm service limit. The brake-disc inspection section specifies replacement below 5.3 mm for the W110 and below 6.3 mm for the W130.

PDF Search, Navigation, and Page Contents

Text search and diagram detail: An embedded OCR layer provides partial text search; some pages and diagram or table details are not searchable, and recognition errors can prevent matches. Bookmarks cover all eight service sections, although the Home Page bookmark points to a separate file. Small wiring labels and connector IDs require zooming.

The download contains one printable, English-language 334-page PDF: 18 preliminary pages, 315 pages across the eight service sections, and one copyright page. This total already includes the cover, section contents pages, and one duplicate copy of the transmission delivery-filter page.
