Boom Repair, Flowshare Hydraulics and Loadall Diagnostics

The following selected repair and diagnostic topics outline the manual's coverage. Other subjects include accelerator-cable adjustment and quick-release coupling service.

• Boom repair: Step-by-step removal, installation, disassembly and assembly for two-, three- and four-stage booms, plus wear-pad replacement and boom shimming.

• Hydraulic systems: Flowshare (LSV/LSV+) and parallel-service pump testing, control-valve overhaul, relief-valve adjustment, cylinder resealing and circuit bleeding.

• Powershift diagnosis: Four-speed relay and ECU controls, five-speed electronic controls, torque-converter stall checks, pressure and flow tests, and fault-finding tables.

• Load indicators: Safe Load Indicator (SLI) and Load Moment Indicator (LMI) testing, calibration, transducer checks and harness fault isolation.

• Steering and brakes: Wheel re-phasing, steering-system bleeding and steering-unit repair, brake leakage tests, and parking-brake caliper and pad service.

• Electrical fault tracing: Serial-specific wiring diagrams, connector references, harness repair, and starter and alternator testing with related inspection procedures.

• Engine and cooling: Engine removal and replacement, engine/bevel-box separation, cooling-package removal and disassembly, and engine-specific fuel-system service.

Written for JCB distributor service engineers who are receiving or have received JCB technical training, this manual assumes sound workshop knowledge and experience maintaining hydraulic earthmoving equipment.

Flowshare Circuits and Boom Hose Routing

Hydraulic coverage distinguishes double- and triple-pump layouts. For 530-70, 535-60 and 540-70 Flowshare machines, the technical data separates units up to S/N 1154455 from S/N 1154456 onward, with inloader and counterbalance-valve changes. These distinctions help match hydraulic tests and circuit diagrams to the installed configuration.

The Flowshare Valve Block Sections exploded view identifies internal assemblies. Smooth Ride System (SRS) coverage adds accumulator diagnosis and charging, supported by the Hydraulic System Schematic.

The Boom – Telescopic Operation illustrations show how out-of-phase movement between three-stage boom sections can damage the internal service hoses.

Electrical Tests and Transmission Controls

Electrical references separate Series I and Series II wiring, sway configurations and control variants. The Transducer Harness Connection view and steering-system Electrical Component and Connector Location references support testing at the harness.

The SLI/LMI test box 892/00905 supports component-level diagnosis; a multimeter-based route is also provided when the box is unavailable. These procedures apply to machines fitted with SLI or LMI, which are not normally installed on North American-market machines.

Four-speed ECU diagnostics include the hand-held test unit 892/00943. Five-speed controls have a separate PC diagnostic route using communications cable 892/00952.

Five-speed ECUs are factory-configured for the transmission variant; software-version labels do not establish interchangeability. The four-speed ECU installation notes warn that overtightened mounting screws can damage the ECU and its internal components.

Axles, Steering and Brake Service Limits

Front-axle references distinguish SD70 and SD80 units; rear-axle coverage separates SD55 and SD80 units. Axle removal, replacement and pinion-seal repair are documented. Steering fault charts address mode-selection and wheel-phasing problems, distinguishing powered-track-rod systems from machines with double-acting wheel cylinders.

Brake procedures include master-cylinder and servo-unit replacement and axle-specific bleeding. Internal gearbox, bevel-box, axle and axle-mounted service-brake overhaul requires the separate Transmissions Service Manual, Publication No. 9803/8610, which is not included.

Maintenance, Engine Scope and Cab Systems

Service schedules, lubricant grades and model-specific lubrication maps cover routine shop work. The optional sideshift carriage and hydraulic tow hitch have dedicated grease and Waxoyl maintenance notes. Hydraulic capacities distinguish tank volume from total system capacity, which depends on installed equipment.

Torque tables cover zinc-plated and Dacromet fasteners, O-ring face-seal connections, BSP and SAE fittings, and Torque Stop hoses, with distinctions for fastener and lubrication conditions.

Engine references separate A-series builds AA, AB, AK, AM and AR from R-series RE, RG and RJ. Fuel priming and filter service vary by engine type. Engine coverage does not extend to a full internal rebuild; injection-system details are referred to separate engine service manuals.

Cab work includes direct glazing and cab removal. Series I and Series II R134a air-conditioning coverage includes leak testing, gauge-based fault diagnosis, recovery, evacuation and recharging; refrigerant work requires specialist training.

Follow the manual's pressure-relief and boom safety-strut precautions before opening hydraulic circuits or working beneath a raised boom.

Sample Flowshare Spool and Solenoid Test Values

For standard Flowshare spools, displacement is specified as 8 mm ± 1 mm in each direction, alongside linkage inspection and adjustment guidance.

Electric-spool solenoid testing specifies 2.5 Ω at 25°C. The test section also explains how the built-in diode affects resistance readings.
