JCB 3CX & 4CX Backhoe Loaders Common Problems This Manual Covers
Weak or slow hydraulics under load
Hydraulic functions that are weak, slow or stop under load usually mean low or contaminated oil, worn pumps, a valve fault or leaks. The Hydraulics section covers the pumps, loader and backhoe valves and their technical data.
Manual Section: Hydraulics p. 226Machine will not start
A no start or intermittent start on these backhoe loaders is traced through the battery, charging, starter circuit and wiring. The Electrics section gives the fuse and relay identification and technical data to find the fault.
Manual Section: Electrics p. 117Poor or inconsistent braking
Spongy or uneven brakes point to wear, contamination or a compensating master cylinder fault. The Brakes section carries the technical data and describes normal and compensating operation of the system.
Manual Section: Brakes p. 658Heavy or erratic steering
Heavy, wandering or unresponsive steering is usually a hydraulic steering fault, low fluid or pump wear. The Steering section covers the steer hydraulics, the 2WS and 4WS schematics and fault finding.
Manual Section: Steering p. 681Engine overheats or loses power
Overheating or power loss can be a cooling restriction, coolant loss or an engine fault. The Engine section covers the engine technical data, removal and replacement and the fuel lift pump.
Manual Section: Engine p. 706Oil seal and gasket leaks
Ageing seals and gaskets on older machines leak and need renewal whenever a joint is disturbed. The Transmission section covers the axles and driveline where these leaks appear, with the seal and O-ring renewal notes.
Manual Section: Transmission p. 444Frequently Asked Questions
Which models does this manual cover?
It covers the JCB 3CX, 4CX, 214, 215 and 217 backhoe loaders and variants built from 1994 to 2007, from machine number 460001. It is publication 9803/3270 with 711 pages.
