For the JCB 3CX and 4CX backhoe loaders: hydraulic cartridge valve 332/G3535, an OEM part.

Cartridges are made to tight tolerances and are sensitive to dirty oil: particles score the spool or poppet and cause internal leakage. The part number decides the choice, as cartridges that look alike can have different functions and settings. The OEM cartridge is made to the same standard as the original and fits the same cavity. Its body is steel and the internals are hardened steel, with the spring and seat deciding the stability of its setting. Rely only on the part number when choosing, since a cartridge of similar size will upset the circuit. After replacing it, check the function under load. The cartridge is supplied new. The OEM cartridge is supplied new with its O-rings fitted; oil them with clean hydraulic oil before fitting. The part number is marked on the cartridge body. The cartridge has a steel body protected against corrosion.

JCB 3CX and 4CX hydraulic circuit diagrams by build year, with component keys

There is no single hydraulic circuit for the JCB 3CX and 4CX backhoe loader: it depends on the build year and the pump type. Section E of the JCB service manual (publication 9803/3290-14) gives separate circuits for the gear pump 3CX built before and after September 2007, for the variable flow 4CX (7-spool and 6-spool), and for the 3C-14 (214e) and 3C machines. Below you will find the circuits themselves, the component keys and some notes on tracing the oil flow through a circuit.

JCB 3CX / 4CX Hydraulic Pressure: Settings, Pressure Testing and Causes of Low Pressure

On JCB 3CX and 4CX backhoe loaders with a gear pump, the working pressure of the hydraulic system is limited by the main relief valve in the loader valve: 236–241 bar on machines up to serial number 964124 and 248–252 bar on machines from serial number 964125 (standard and high-pressure hydraulics). It is checked with a 0–400 bar pressure gauge connected to the loader valve test point, with the engine at 1500 rev/min and the oil warmed to 50 °C. Below are the settings, the test procedure and the reasons why pressure drops, taken from the JCB service manual (Section E).
