SYSTEMS DESCRIPTIONS
The engine should not be operated on less than nine quarts of oil. To
minimize loss of oil through the breather, fill to 10 quarts for normal
flights of less than three hours. For extended flight, fill to 12 quarts
(dipstick indication only). For engine oil grade and specifications, refer to
Section 8 of this handbook.
The oil cooler may be replaced by a non-congealing oil cooler for
operations in temperatures consistently below 20°F (-7°C). The non-
congealing oil cooler provides improved oil flow at low temperatures.
Once installed, the non-congealing oil cooler is approved for permanent
use in both hot and cold weather.
An oil quick-drain valve is available to replace the drain plug on the
bottom of the oil sump, and provides quicker, cleaner draining of the
engine oil. To drain the oil with this valve installed, slip a hose over the end
of the valve and push upward on the end of the valve until it snaps into the
open position. Spring clips will hold the valve open. After draining, use a
suitable tool to snap the valve into the extended (closed) position and
remove the drain hose.
IGNITION-STARTER SYSTEM
Engine ignition is provided by two engine-driven magnetos, and two
spark plugs in each cylinder. The right magneto fires the lower left and
upper right spark plugs, and the left magneto fires the lower right and
upper left spark plugs. Normal operation is conducted with both magnetos
due to the more complete burning of the fuel-air mixture with dual ignition.
Ignition and starter operation is controlled by a rotary type switch
located on the left switch and control panel. The switch is labeled clock-
wise, OFF, R, L, BOTH, and START. The engine should be operated on both
magnetos (BOTH position) except for magneto checks. The Rand L
positions are for checking purposes and emergency use only. When the
switch is rotated to the spring-loaded START position, (with the master
switch in the ON position), the starter contactor is energized and the
starter will crank the engine. When the switch is released, it will automati-
cally return to the BOTH position.
AIR INDUCTION SYSTEM
The engine air induction system receives ram air through an intake in
the lower front portion of the engine cowling. The intake is covered by an
air filter which removes dust and other foreign matter from the induction
air. Airflow passing through the filter enters an airbox. After passing
through the airbox, induction air enters the inlet in the carburetor which is
under the engine, and is then ducted to the engine cylinders through intake
