3. LUBRICATING SYSTEM

A lubricating system consists of an oil strainer (9), oil pump (8), relief valve (10), oil filter cartridge (11), oil cooler
(17) and oil pressure switch (2).
The oil pump sucks lubricating oil from the oil pan through the oil strainer and the oil flows down to the oil filter,
cartridge where it is further filtered. Then the oil is forced to crankshaft (7), connecting rods (16), idle gear (6),
governor shaft (5), camshaft (14) and rocker arm shaft (3) to lubricate each part through the oil gallery.
