Tank Fill Control (Optional)
With the reserve oil system the engine oil level is held
constant, with only the reserve tank needing routine fill-
ing. The fill system automatically controls the filling of
remote tank from a convenient ground level position.
Filling of the tank to the proper "FULL" level is fast and
accurate and accomplished in 2 to 3 minutes.
The reserve oil tank for the engine is designed to add
more oil capacity to the engine to reduce the frequent
servicing of the engine oil. The engine oil level must
still be checked every shift using the dipstick.
If the engine oil has been drained from the engine oil
pan, the new oil must be added through the engine fill
tube. After an oil change, both engine and reserve tank
must be full of oil before starting the engine.
NOTE: DO NOT use the oil in the reserve tank to fill the
engine pan.
The system switch (2, Figure 31-3) is an illuminated
push-pull POWER ON switch that powers the fill sys-
tem. The start switch (3) is a momentary push button
switch that opens the fill valve mounted on the reserve
tank to begin the automatic filling of the reserve tank.
Supply oil under pressure flows through the fill valve
and into the tank.
