Assembling the oil pump
(a)
Install
the
rotor
assembly
in
the
oil
pump body.
(b)
Install
the
oil
pump
shaft to the crankcase
with its lug properly
fi tted in the slot in
the camshaft.
(c)
Replace
the
O-ring
with
a
new
one
and
install
the
pump
cover.
Apply oil
to
the O-ring and install
it squarely on the 0-
ring groove.
Oil Pressure Switch
The oil pressure swi tch
is located at
the
rear
right
side of
the
crankcase and, when the lubricating system pressure becomes lower than
18 to 23 PSI dur ing normal oper ation, this swi tch oper ates an alarm
buzzer.
When the alarm sounds, check the oil pressure and water tem-
perature gauges on your instrument panel.
NOTE:
The
alarm can
also
be
activated
by an overheat switch
which will activate the alarm should the operating temperature of
the engine reach 205· F.
Should the oil pressure be low, stop the engine and investigate.
Check the oil pressure switches, and if they do not meet the specifi-
cations, replace them.
NOTE:
Generator
units have a two-prong oil pressure and water
temperature switch which interrupts the circuit for the fuel run
solenoid when tripped, thus shutting down the generator automati-
cally.
