STARTING
1. GENERAL
This chapter describes the components used for starting the airplane engine. This includes the starter. For
additional information on starter system components, refer to the Teledyne Continental Motors Model IO-
550 Overhaul Manual indexed in the List or Publications in the front of this manual.
The starting system employs an electric starter motor mounted on a right angled starter-to-engine adapter.
The right angle drive adapter serves to shorten the engine’s overall length. As the starter motor is electri-
cally energized, the adapter worm shaft and gear engage the starter shaftgear by means of a spring and
clutch assembly. As the shaftgear rotates, it in turns rotates the crankshaft gear and crankshaft. When the
engine starts and accelerates, the gripping action of the clutch spring is relieved, disengaging the shaft-
gear from the worm shaft and electric starter motor.
