3-1 Lube oil filter construction
The lube oil filter is a full-flow paper element type, mounted to
the side of the cylinder block. It is an easy to remove cartridge
type filter. To prevent seizure in the event of the filter clogging
up, a bypass circuit is provided in the oil filter. The bypass
valve in the filter element opens when the difference in pressure
in front and behind the paper element reaches 0.078-0.118
(0.8.-1.2)MPa(kgf/cm').
