Supply unit drive
The supply unit drive is installed at the driving end of the engine on the fuel side.
The crankshaft gear wheel (003,
) moves the intermediate wheel (001). The
intermediate wheel (001) moves the intermediate wheel (006).
The gear wheel (005) operates the gear wheels (004) for the servo oil pumps. The camshaft of
the gear wheel (005) also operates the fuel pumps.
Oil flows through an oil inlet to lubricate the bearings of the gear wheels (004). Oil also flows
through the nozzles in the bearing housing to lubricate the teeth of the gear wheels (004) and the
gear wheel (005).
If you hear unusual noises from the area of the supply unit drive, you must find the cause and
repair the fault immediately.
