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

Fuel injection pump, rebuilt 320/06929 is an OEM part for the JCB 3CX and 4CX backhoe loaders. According to the product card, this is a rebuilt pump.

The plungers, rotors and valves inside the pump, working thousands of times a minute, are made with clearances of a few microns. The pump is therefore opened only in a clean room, and its internal settings are made in a fuel injection workshop with a test bench, where its delivery, timing and pressures are measured. These values are needed for the engine to give its rated power and meet emission limits. Field adjustments to the pump can make the engine overheat and its parts wear early.

Fitting

Before removing the pump, turn the engine until the timing marks line up and mark the position of the pump gear. Cap the fuel line ends at once. 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.
