2-2.7. Starter Assembly
The Starting System consists of an electric starter motor mounted on a right angle starter
drive adapter. When the starter motor is electrically energized, the adapter worm shaft
and gear engage the starter shaftgear through a spring and clutch assembly by turning the
starter worm wheel.
As the shaftgear turns, it rotates the crankshaft gear and crankshaft. When the engine
starts, electrical energy is removed from the starter motor. The gripping action of the
clutch spring is relieved, disengaging the shaftgear from the worm shaft and electric
starter motor. The starter shaftgear extends from the rear of the starter adapter.

2-2.8. Alternator
The standard configuration gear-driven alternator is mounted on the right front crankcase
half. The alternator generates electrical current for recharging aircraft batteries and
powering the aircraft electrical system. An optional belt-driven alternator is available
through TCM. TCM alternators are available in multiple voltage output options to match
aircraft circuit requirements.
