OIL M A K E - U P SYSTEM
The Oil Make-up System functions to prevent dangerously low engine
crankcase oil levels during operation. The system consists of (1) an
Oil Make-up TANK with low oil level shutdown switch, (2) an Oil Make­
up PUMP, (3) an Oil Make-up PROBE, and (4) interconnecting lines.
t
The Oil Make-up' Pump will not act
while the tip of the Oil Make-up
Probe is submerged in oil. If oil
level in the crankcase should drop
to about the 48 ounce level, the
tip of the Probe will be exposed to
crankcase vacuum/pressure pulses.
These pulses actuate the Oil Make­
up Pump diaphragm and the pump ac­
tion then draws oil from the Tank. ■
When the Probe tip is again submerg­
ed in oil, pumping action stops.
If Oil Make-up Tank oil level
should drop below the OIL CHANGE
LEVEL arrows on the tank side,
the float-operated Low Oil Level
Shutdown Switch will ground the
engine ignition system and the
engine will automatically shut
down.
During initial filling of the engihe
crankcase, approximately 56 ounces
(3^ pints) of oil is added. This a-
mount of oil brings the oil level up
to the oil dipstick FULL mark. The
Oil Make-up System will not start to
pump oil into the crankcase until
oil level has reached the 48 ounce
point, about halfway between the dip­
stick FULL mark and ADD 1 PINT mark.
