Fuel injection pump 320/06929 JCB 3CX/4CX, OEM

For the JCB 3CX and 4CX backhoe loaders: fuel injection pump 320/06929, an OEM part.

The pump is chosen by part number for the engine type and version: pumps for different power versions of the same engine are set differently, and the wrong pump changes power, smoke and fuel use. The pump maker's number on the card identifies its calibration. Before replacing the pump, check the fuel filters, water separator and lift pump, as the cause of failure is often poor supply or dirty fuel, and unless that is fixed a new pump will soon fail too.

Fitting

Fit the new pump in the timed position following the engine maker's instructions and tighten the connections with new seals to the specified torque. Then bleed the fuel system, without cranking for long on the first start. Once the engine runs, check for fuel leaks, idle, smoke and power, and read the fault codes on electronic systems. In the first hours, keep an eye on fuel consumption and exhaust smoke.
