Engine Lubrication System - Suzuki RV50 Service Manual

Engine lubrication System

The engine lubrication is the Suzuki CCI system as in all other Suzuki models. The oil pump has 2 outlets
connecting with respective oil feeding pipes and lubricate all the moving parts of the engine except the.
crankshaft right end bearing which is lubricated by transmission oil. The oil pump driving force is transmit­
ted from the crankshaft to the pump through the primary pinion, primary gear, kick starter gear, idle gear
and kick starter pinion as illustrated below.
The plunger and the differential plunger are always pressed to the right side by the spring and their move­
ments to the right are restricted by the cam or the stationary base fitted on the right side of the pump body.
The plunger is worm geared in its center part which engages the driving worm. When the driving worm
turns, the plunger also turns together with the differential plunger and moves left and right according to the
cam shape, which is machined on the right end of the plunger.
