OIL SYSTEM

In the Bonanza's oil system, oil is fed to the engine oil pump from a supply tank mounted just above and
behind the engine. The return oil is picked up by a scavenging pump and returned to the supply tank,
passing through a cooler which is an integral part of the tank. The oil tank capacity is 2-1;2 gallons. The
filler neck of the A35 is accessible by raising the left engine cowling. The B35 has an access door on the
left upper cowl. The level should be checked after each flight using the dipstick fastened to the filler cap.
The normal oil operating level should be maintained at 8 to 10 quarts. Both oil pumps, the oil screen and
a check valve to prevent oil from draining from the tank into the engine sump are incorporated in the
engine accessory section. There is no engine oil shut-off valve and the system is so designed that oil
bypass arrangements are unnecessary.
The push-pull throttle and mixture controls are
located on and to the left of the control console
respectively. These controls are released for
repositioning by pushing a button on the knob.
With the button extended.
On the mixture control, releasing the knob locks
the control. The control is pushed in for full rich
and pulled out to the end of its travel for idle cut-
off.
Propeller pitch is controlled by a three-position
toggle switch on the control console, just to the
left of the throttle.
The push-pull cowl flap control is located to the left
of the control console on the subpanel. Except in
extremely low temperatures. The cowl flaps should
be open during ground operation, take-off, and
climb.
