DESCRIPTION AND OPERATION
Lubrication system
The lubrication system comprises the sump, pump, oil
filter and oil ducts.
Sump
This is a one-piece, rigid, aluminium, die-cast unit
bolted to underside of the crankcase. 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 pipe.
Oil pump
An internal gear-type pump is mounted on the front
end of the crankshaft. It is directly driven by the
crankshaft. The pump consists of a body which
houses a driven rotor and a stator. Pump pressure is
regulated by a piston operated pressure relief valve
housed within the body of the pump.
