MAN Injection pump with actuator 51111027971

About this part

Genuine MAN injection pump with actuator for the D2866 LE builds. The actuator is the electrical interface to the pump's fuel rack: instead of a purely mechanical governor setting fuelling from speed and load, an electronic control unit commands rack position through the actuator, which allows far finer control of fuelling and makes features like electronic speed setting and load limiting possible. The practical implication when diagnosing is that a fuelling fault on such a system may lie in the actuator, its wiring or the control unit rather than in the pump's hydraulics — and those are separable. Confirm that the actuator is receiving and responding to commands before a pump is condemned. A multimeter at the actuator connector distinguishes a control fault from a hydraulic one in minutes and costs nothing.

Supplied new, in the manufacturer’s packaging, with our warranty of up to 24 months.
