Control valve spool 25/970800A is an aftermarket part for the JCB 3CX and 4CX backhoe loaders.

The spool surface is hardened and precision-ground and fits its bore in the body with a clearance of a few microns. As that clearance grows, oil bypasses the spool and the cylinder moves slowly even in neutral. One end carries the control linkage and the other the centring spring, which returns the spool to neutral when the lever is released. If the valve body is sound, replacing the spool is far cheaper than replacing the whole valve. The spool is supplied new, and its surface must be protected in transit, since even a small scratch can cause leakage. The spool is made of steel.

Compatibility

The spool is offered for the control valve listed on the card; compare its length, number of lands and linkage end with the old spool. Other parts are in Hydraulic control valves.

Fitting

Oil the spool with clean hydraulic oil and slide it into the bore without force, turning it slightly; if it binds, recheck the bore and spool. After assembly, work the lever in every direction to confirm the spool moves freely.

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).

JCB 3CX / 4CX Hydraulics: Circuit Diagrams, Pumps and Relief Valve Pressures

Section E of the JCB service manual (publication 9803/3290-14) deals with the hydraulic system of the JCB 3C, 3CX and 4CX backhoe loaders. It brings together technical data for the pumps and valve blocks, hydraulic circuits for machines of different build years, valve operation, fault finding tables, and the procedures for pressure testing and for overhauling the pump, valves and rams. The section PDF runs to 302 pages.
