Tank Fill Control (Optional)
With the reserve oil system the engine oil level is
held constant, with only the reserve tank needing
routine filling. 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.
System switch (2, Figure 31-3) is an illuminated
push-pull POWER-ON switch that powers the fill sys-
tem. 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.
