LUBRICATION

CIRCUIT

The

pressure
lubrication

of
the

engine
is

accomplished
by
a
tro

choid

type
oil

pump
This

pump

draws
the

oil

through
the
oil
strainer

into

pump

housing
and
then
forces
it

through
the
full
flow

oil
filter

into
the

main
oil

gallery
Part
of
the

oil
is

supplied
to
all
crankshaft

bearings
chain

tensioner
and

timing

chain

Oil

supplied
to
crankshaft

bearings
is
fed
to
