3.2. Engine Lubrication
The engine is equipped with force-feed lubrication.
The pressure is produced by a gear pump whose drive gear is in direct mesh with the crankshaft
gear at the flywheel end.
The oil pump draws the oil from the oil sump and delivers it through the oil cooler and oil filter
to the main distributor gallery and from there to the main bearings, big-end bearings and
camshaft bearings as well as to the small-end bearings and the rocker arms.
