. A separate single-row chain drives the oil pump. The camshaft operated the valves via hydraulic bucket tappets; valve clearance adjustment is automatic. The water pump is driven via the single serpentine belt, which also drives all other accessories. On many OM602 engines fuel injection is indirect. A Bosch PES in-line injection pump is used, with a mechanical governor and vacuum-operated stop control. The pump is lubricated by a connection to the engine oil circulation and the fuel lift pump is mounted on the side of the injection pump. Some later versions of the capacity unit use a Bosch VE-style rotary distributor injection pump with electronic control and have a significantly different
