OILING SYSTEM
COMPONENTS
8
Cylinder and Crankcase
The primary oil distribution manifold provides
crankcase lubrication through oil distribution
hoses and pressed-in fittings at the front of the
crankcase, port side.
The rear oil distribution manifold provides lubrica-
tion for each cylinder. Each cylinder of the cylin-
der/crankcase has a pressed-in fitting which is
connected to an oil distribution hose.
Oil Recirculation System
External hoses and fittings, internal cylin-
der/crankcase passages, and intake manifold pas-
sages are used to recirculate any accumulation of
oil from various locations in the powerhead. The
movement of oil is controlled by check valves.
Cylinder Recirculation
Internal powerhead oil drain passages connect
the lowest point of the intake port area of the cylin-
der block to external check valves. External hoses
connect these check valves to a hose fitting
pressed into the top of the intake manifold / throt-
tle body. Intake manifold vacuum draws any accu-
mulation of oil from the intake port area of the
cylinders into the incoming air stream in front of
the top reed valve.
