MAN Timing gear - crankshaft 51021156076

About this part

Genuine MAN crankshaft timing gear covering the D2866 LE401, D2840 LE301, D2842 LE443 and D2848 LE422 — an in-line six, a V10 and two V-configuration engines sharing one gear. Common parts across layouts are normal at the crankshaft nose, where the interface is the shaft diameter and keying rather than anything to do with cylinder arrangement. For a yard or a mixed fleet that makes this a sensible number to hold, since it covers four engine rooms. In service the thing to watch is not the gear in isolation but the backlash in the train it belongs to: this generation drives the injection pump from the same gears as the camshaft, so accumulated wear moves injection timing, and the earliest sign tends to be a change in starting behaviour rather than a noise.

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