17-1 STARTER AND STARTER ADAPTER DESCRIPTION
The L/TSIO-360-RB engines utilize a starting system that employs an electric starter
motor mounted on a right angle drive adapter. As the starter motor is electrically
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 turn rotates the crankshaft gear
and crankshaft. After engine start, the clutch spring disengages from the shaftgear.
The TSIO-360-RB engines utilize an accessory drive adapter and freon compressor
mounting brackets. The accessory drive adapter has provisions for installing a sheave on
an extended shaft.
Accessories may be mounted on either of the drive pads provided. See Chapter 15.

17-2 STARTING SYSTEM COMPONENT DETAIL DESCRIPTION
Starter - For a detailed description of TCM electric starter motors see TCM Form X30592,
Starter Service Instructions. See Section 1-4," Related Publications" for ordering
information.
Starter Adapter - The starter adapter assembly uses a worm drive gear shaft and worm
gear to transfer torque from the starter motor to the clutch assembly. The shaft is
supported in the housing at the starter end by a ball bearing and retaining ring, the
opposite end is supported by a needle bearing pressed into the adapter housing. As the
worm gear rotates the worm wheel and clutch spring, the clutch spring is tightened around
the drum of the starter shaftgear. As the shaftgear turns, its torque is transmitted directly
to the crankshaft gear. The starter shaftgear is supported at the adapter cover by a
pressed in ball bearing, and is supported at the opposite end by a needle bearing in the
crankcase. The L/TSIO-360-RB starter adapter rotates the crankshaft in a clockwise
direction.
