Sump
The two-piece aluminium die-cast sump, with an integral tunnel for the differential drive shaft, is sealed to the lower
crankcase extension using a rubber metal-backed gasket. The sump is fixed to the lower crankcase extension using
25 bolts. An oil deflector plate is attached to the crankcase reinforcing shell above the sump. The sump incorporates
a drain plug and a dip-stick guide tube.
Oil Pump
The oil pump housing and cover is manufactured from cast aluminium. The gear type oil pump is driven via the
crankshaft.
The oil pump is located in the sump and is attached to Nos 1 and 2 main bearing caps. The rotor-type pump produces
a regulated pressure of approximately 4.5 bar.
A metal suction pipe obtains oil from the sump.
