MAN Drive gear injection pump 51113010230

About this part

Genuine MAN injection pump drive gear for the D2840 LE301. This gear takes the pump's drive from the engine's timing train, and its tooth condition directly affects the accuracy with which injection timing is held — wear produces backlash, and backlash lets the pump's angular position drift relative to the crankshaft under changing load. That drift is small and its effects are subtle: slightly harder starting, a change in smoke, a loss of efficiency that shows up on fuel consumption rather than on the rev counter. Measuring backlash against specification is the assessment that matters, since tooth wear of this order is not obvious by inspection. Fuel consumption logged over time is often the first place this kind of drift becomes visible on a working boat.

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