Part of the JCB Repair Manuals.
This JCB service manual covers the Fastrac 125, 135, 145, 150, 155 and 185 tractors. It is the factory workshop document, publication number 9803/8000, running to 677 pages, and it covers both the Perkins 1006 series engines (including the 1006-6, 1006-6T and 1006-6T4) and the Cummins 6BTA fitted to these machines.
The manual works through every major system: general torque settings and service tools, the electrical system with wiring repair, hydraulics, the full transmission with front and rear axles, brakes, steering and the Fastrac suspension. Technical data, fault finding and dismantling procedures are given section by section.
Use it to diagnose a transmission fault, service the hydraulics, trace an electrical problem or rebuild the suspension. This is the same information a JCB distributor service engineer works from, delivered as a PDF you can download and print.
