Machines and Engines Covered

This JCB Robot service manual covers the Robot 150 and Robot 165 skid steer loaders, along with the Robot 165 Hi-Flow. Two engine families are documented: the Peugeot XUD 4-cylinder 1905 cm3 naturally aspirated diesel engine, and the JCB Diesel 4-cylinder 2216 cm3 naturally aspirated diesel engine. Coverage is broken down by machine serial number throughout the manual, with separate procedures for machines up to and from key production breaks such as 676354, 676355, 676701, 676702, 677000, 677001, 677052, 677723, 678000, 678316 and 678410. This allows you to follow the exact procedure for your machine rather than a generic description.

Servo and Manual Control Machines

The Robot 150 and 165 were built with two control systems and this manual covers both. Servo machines use hydraulic joystick controls to operate the loader and drive functions, with pressure regulation through a pressure reducing solenoid valve (early) or a brake valve (later). Manual machines use control levers mechanically connected to the transmission pump and loader valve block. Loader valve dismantling is described separately for manual spools, servo spools and solenoid spools, so you can identify your valve section before starting work. The hydraulic schematic section is also split by serial number and control type, which makes tracing circuits far quicker.

Diagnostics and Problem Solving

Fault-finding is treated as a first-class part of the job rather than an afterthought. The hydrostatic transmission problem-solving chapter lists symptoms, likely causes and remedies across both servo and manual machines, covering no drive in any direction, no drive forward or reverse, no spin turn, loss of drive on one side, veering, brake faults and creeping in neutral. Supporting test procedures include swapping motor feed hoses to isolate pump versus motor faults, checking wheel speed with a stroboscopic meter, checking motor leakage rate against a pressure/flow table, pump main pressure test points, brake circuit pressure checks and joystick hydraulic line checks. Loader valve main relief and auxiliary relief valve pressure testing procedures are included, both in situ and on the bench using a hand pump.

Who This Manual Is For

This JCB Robot 150 & 165 skid steer loader service manual is written for anyone who has to keep these machines working – independent workshops, plant hire fitters, agricultural contractors, groundworks crews and owner-operators. It is a working document: you can print the pages you need for a job, take them into the workshop and keep the rest clean. Everything from a routine 50-hour engine oil and filter change to a full hydrostatic pump rebuild, a wheel hub strip-down, a backhoe valve block overhaul or a wire-by-wire electrical trace is covered with the figures and tolerances a technician actually needs.

Why Correct Procedures and Specifications Matter

Skid steer loaders concentrate a lot of hydraulic, mechanical and electrical complexity into a small chassis, and guessing at pressures or torques is expensive. A hydrostatic pump set up wrong, a relief valve adjusted by feel, a chain tensioned unevenly or a ram end cap torqued without the correct locking compound can all turn a straightforward repair into a repeat failure. This manual supplies the manufacturer’s torque settings, relief valve pressures, charge pressure figures, ram bore and stroke data, plate pack dimensions, tyre pressures, chain adjustment values, service intervals and lubricant specifications so each step is done to the correct standard the first time.

Coverage Highlights

• Full routine maintenance schedules from daily checks up to 2000-hour / 2-yearly service items
• Engine oil, fuel filter and cooling system service for both the Peugeot and JCB Diesel engines
• Drive chain oil level, oil change and tension adjustment procedures for both hub designs
• Hydrostatic pump removal, coupling alignment, start-up and priming procedure, neutral and servo adjustment
• Drive motor removal, dismantling, brake pack service and assembly alignment marks
• Loader valve block removal, section-by-section dismantling and relief valve pressure testing
• Backhoe attachment valve block, stabilisers, dipper and boom, ram removal and dismantling
• Complete electrical circuit diagrams by machine number, plus wire number identification tables for panel/cab, mainframe and front roof harnesses
• Towing and winching preparation procedures, including hydrostatic brake release
