PDF Search, Bookmarks and Wiring Detail

Text search and diagram labels: The written chapters support text search, and 59 embedded bookmarks provide section and chapter navigation. Labels inside some wiring diagrams are not searchable. Small pin numbers, connector references and wire codes require zooming in the checked diagrams.

One printable, English-language PDF with 983 pages, including 13 preliminary pages—cover and introductory material, eight contents pages and one blank page—and 27 notes pages.

Drivetrain, Hydraulic and Backhoe Repair

Beyond the selected topics below, the manual also covers cab-heater service and air-conditioning compressor overhaul.

• Transmission repair: Step-by-step disassembly, inspection, reassembly and shimming for 4x4 Compact Shuttle and PowerShift units, plus torque-converter service.

• Axles and differentials: Front- and rear-axle overhaul, planetary hubs, crown-wheel and pinion adjustment, and separate procedures for four-wheel-steer assemblies.

• Hydraulic diagnosis: HUSCO and REXROTH fault charts, pressure and pump-flow tests, and loader and backhoe control-valve overhaul.

• Cylinders and pumps: Loader, backhoe, stabilizer and swing-cylinder service, together with hydraulic pump and flow-divider overhaul.

• Steering and brakes: Hydrostatic steering repair, four-wheel-steering checks, wet-disc brake service, bleeding and parking-brake adjustment.

• Electrical troubleshooting: Variant-specific wiring diagrams, connector details, PowerShift fault codes, starter and alternator tests, speedometer calibration and immobilizer circuitry.

• Loader and backhoe: Control-linkage overhaul, self-leveling and return-to-dig adjustments, boom and dipperstick removal, and extendible-dipperstick wear-pad service.

Written for skilled technicians, this manual specifies that maintenance and repair work be carried out by authorized workshops using the indicated special equipment.

PowerShuttle and PowerShift Assemblies

The transmission sections explain the rotor-type hydraulic pump, oil distributor and solenoid control valves before moving into shaft, bearing and clutch work. The transmission case serves as the oil reservoir for the torque converter and clutch assemblies.

Transmission Power Flows and Transmission Hydraulic Valves and Pressure Test Points connect the mechanical layout with the circuits used in diagnosis. Keeping these drawings alongside the test procedures lets you cross-reference hydraulic operation and component assembly during workshop repairs.

PowerShift overhaul extends to the individual clutch packs and four-wheel-drive disconnect output shaft. Dedicated equipment includes piston spring compressor 380000711; the internal overhaul procedures also call for a workshop press and induction heater.

Engine-work limit: Engine/transmission assembly removal is covered. The referenced Section 10 for internal engine repair is not included in this PDF.

HUSCO and REXROTH Hydraulic Systems

Separate chapters cover the two valve systems rather than treating their test procedures as interchangeable. REXROTH coverage distinguishes mechanical and hydraulic controls and explains the fixed-displacement pump’s load-sensing flow-sharing arrangement.

The Load Sensing Flow Sharing Hydraulic System diagram supports circuit tracing, while fault charts distinguish pump, loader and backhoe symptoms. Cylinder sections cover removal, seal work and reassembly for the loader, backhoe, stabilizers and swing system.

The REXROTH spool-seal section warns that the spool grooves can damage the lip seal during replacement and compromise sealing.

Axle, Steering and Brake Variants

Rear-axle procedures distinguish foot-operated and electrically operated differential locks. Separate sections address the steering axles fitted to 4WS machines, including crown-wheel and pinion setup.

Brake coverage identifies the different wet-disc arrangements and includes hydraulic bleeding and handbrake adjustment. General metric and inch hardware torque charts supplement the component-specific assembly specifications.

Wiring and Component-Level Diagnosis

European and North American wiring is organized into separate PowerShuttle, PowerShift and ROPS sections, with connector details and wire-color legends. System from Key-Operated Start is one of the circuit schematics provided.

Starter Motor — Exploded View and 12 V / 90 A Alternator — Exploded View accompany the component inspection and testing sections. PowerShift fault-code charts address shift-lever inputs, speed sensors and output-circuit faults; the 4WS checks identify steering-sensor connectors and solenoid outputs.

Loader Linkages and Extendible Dipperstick

The attachment sections go beyond operating descriptions, with step-by-step procedures for loader-arm and bucket removal, backhoe carriage and swing-post removal, and extendible-dipperstick wear-pad replacement.

The wear-pad section explains shim adjustment and warns that overtightening the retaining bolts can damage the threaded inserts.

Heavy equipment maintenance carries inherent risks; always ensure standard safety protocols are followed and consult a certified specialist if you lack the necessary tooling or expertise for working on high-pressure hydraulic circuits.

Examples of Shuttle Clearances and Coil Test Values

The 4x4 Compact Shuttle section specifies four-wheel-drive shaft end float at 0.050–0.28 mm. Separate bearing end-float limits and available shim sizes support the reassembly and shimming procedures.

For PowerShuttle electrical checks, the forward/reverse valve coils are specified at 5 ohms, while the four-wheel-drive solenoid coil is 7 ohms, measured at their connectors. These are separate component specifications.
