- All the features
For the JCB 3CX and 4CX backhoe loaders: check valve 332/D1079, an aftermarket part. The card also lists 332/D7251.
Inside a check valve is a spring and a poppet that the spring holds against its seat; when oil pressure overcomes the spring, the valve opens, and in the reverse direction pressure keeps it shut. The opening pressure is set by the spring, so a valve with a different spring changes how the circuit works. When fitting, renew the joint seals and check the flow direction against the mark on the body, since a check valve fitted the wrong way shuts the line completely. The aftermarket valve has the connection dimensions and opening pressure of the original, while the genuine valve comes with the setting JCB specifies. The valve comes new with its O-rings fitted.

Fitting
After changing the valve, run the related function through its full stroke several times to bleed the circuit. Check the valve joint again after the first hours of work, since a slight leak can mean an O-ring has not seated properly.
