2003–2007 New Holland B110 & B115 Loader Backhoe Repair Manual (P/N 87643846)

This New Holland repair manual, Print No. 87643846, covers the 2003–2007 B110 and B115 loader backhoe series, with Powershuttle, Powershift, 2WS, and 4WS configurations.

Text search and schematic detail: Service text is searchable, but some hydraulic diagrams, legends, and wiring labels are outside the searchable text. There are no embedded PDF bookmarks. Small schematic labels require zooming.

• Transmission repair: Powershuttle and Powershift torque-converter testing, transmission removal and installation, clutch disassembly and reassembly, and mechanical, hydraulic, and electrical fault diagnosis.

• Axles and brakes: Front and rear axle overhaul, differential adjustment, brake master-cylinder service, parking-brake adjustment, and brake-system bleeding.

• Hydraulics: CASAPPA pump service, Rexroth mechanical and pilot control valves, load-sensing circuits, hydraulic-cylinder repair, relief-valve testing, and flow-related troubleshooting.

• Steering: Hydrostatic steering-unit disassembly and assembly, pressure testing, and diagnosis of 2WS and 4WS controls, sensors, and solenoids.

• Electrical systems: Configuration-specific wiring diagrams, component tests, diagnostic-display setup and self-tests, onboard error-code retrieval, immobilizer circuitry, and speedometer calibration.

• Loader and backhoe: Attachment removal and installation, bucket self-leveling and return-to-dig adjustment, mechanical and hydraulic controls, and telescopic-dipper guide-pad service.

• Cab heating and A/C: Heater troubleshooting, refrigerant-circuit testing, flushing, evacuation and charging, component replacement, and compressor overhaul.

Written for skilled service engineers, the manual assigns the described maintenance and repair work to authorized workshops using the specified equipment.

Engine Scope and Transmission Repair

Engine coverage identifies the Iveco F4HE9484C*J102 for the B110 and F4HE9484C*J103 for the B115, with specifications and engine/transmission removal information. Internal engine repair requires the separate Engine Service Manual, Print No. 87643867, which is not included.

The B110 transmission sections cover the Turner COM-T4-2025 Powershuttle and Dana T16000 Powershift; the B115 uses the Dana Powershift. Illustrated component keys and gear-and-clutch layouts support disassembly work. Transmission hydraulic and power-flow diagrams explain operation.

Dana EGS fault charts and pressure-test points help narrow a shifting problem to its electrical, hydraulic, or mechanical cause before transmission removal. Tool references include the Powershuttle shimming adapter 380002693 and Powershift lifting tool 380000676.

Axle, Brake, and Steering Service

Carraro coverage distinguishes the 26.16 and 26.28 front axles and the 26.32 rear steering axle, alongside the 2WS rear axle. Repair procedures address wheel hubs, planetary reductions, differential assemblies, pinion shimming, and bearing preload.

Separate brake layouts show the 2WS and 4WS arrangements. Master-cylinder operation, wet-disc brake components, and parking-brake wear specifications accompany the service procedures. Differential-lock pedal operation is also described.

The steering material includes control-valve overhaul and fault-finding tables. The 4WS section adds steering-selector, axle-sensor, and solenoid tests, supported by the Steering Schematic.

Hydraulic Controls and Attachment Adjustments

The CASAPPA twin gear pump, load-sensing valve, Rexroth control blocks, and Parker Glide Ride accumulator receive separate treatment. Hydraulic diagrams distinguish 2WS sideshift mechanical and 4WS center-pivot pilot configurations, among others, so the circuit can be matched to the machine's controls.

Cylinder sections cover loader, bucket, boom, dipper, swing, stabilizer, and sideshift-locking assemblies, including short and long telescopic cylinders. Mechanical stabilizer controls and the backhoe's standard, ISO, four-lever, and cross-pattern layouts are documented.

Telescopic-dipper repair includes guide-pad inspection, adjustment, and replacement. The manual warns that overtightening the pad-retaining screws can damage the threaded inserts.

Electrical Diagnosis and Cab Systems

Separate wiring sets serve Powershuttle cab, Powershift cab, and 4WS machines. The Start Circuit Engine Schematic, connector pin tables, and immobilizer circuit support circuit tracing alongside starter, alternator, and battery tests.

Diagnostic-display pages explain setup menus and self-tests, with symbol charts, warning messages, and stored-code occurrence counts. Speedometer calibration tables account for transmission type, axle ratio, and tire rolling circumference.

The HFC-134a air-conditioning section pairs circuit illustrations with Performance Test Diagnosis Charts and manifold-gauge interpretations. It also covers leak testing, expansion-valve and receiver-dryer replacement, and compressor repair.

Service Data and Workshop Precautions

Reference tables provide drivetrain tightening torques, hydraulic test specifications, engine and drivetrain fluid capacities, electrical test values, and component inspection limits.

Before beginning diagnostic, repair, or maintenance work, review the manual's safety precautions for raised attachments, residual hydraulic pressure, and heavy assemblies.

English PDF and Included Pages
