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.
