This JCB service manual covers the 3CX, 4CX, 214, 215 and 217 backhoe loaders and their variants from machine number 460001 onwards. It is the factory workshop document, publication number 9803/3270, running to 711 pages, for machines with the 1000 Series four cylinder engines.
The manual works through every system: general information and torque settings, the electrical system with fuse and relay identification, the loader and backhoe hydraulics, the transmission with front and rear axles, brakes, steering and the engine. Technical data, fault finding and overhaul procedures are given throughout.
Use it to trace a hydraulic fault, diagnose an electrical or starting problem, overhaul the transmission or set up the steering. This is the information a JCB service engineer works from, delivered as a PDF you can download and print.
