Lubrication Features

The oil pump is a "Duocentric" also known as an Eaton Rotary type of tandem design (similar to the M70 oil pump).

The pump is bolted to the engine block in the oil sump, and driven directly from the crankshaft by a single roller chain with a tensioner.

The single-piece pressure-cast aluminum oil pan incorporates an oil deflector and a baffle plate which maintains the oil supply reliability in extreme conditions and prevents engine oil foaming.

A single-piece gearbox support is integrated into the oil sump so that a separate stiffener is not needed. This rigid link between engine and gearbox reduces vibration loads on the entire driveline, and therefore keeps noise transmission low.

The oil filter is mounted vertically on the intake side of the engine. The paper filter element is accessed from above when replacing it.
