Bearing.
7. Slide the assembled Gear Case Cover, bearing recess rst, down
over the Drive Shaft until it seats against the Gear Case.
NOTICE
Check the inner lip of the Drive Shaft Grease Seal to make certain
that it did not fold outward toward the end of the Drive Shaft. If
it did fold outward, you must reinstall the Gear Case Cover using
a ne pointed instrument to roll the lip of the seal the proper
direction.
Assembly of Drive Housing
1. If the Drive Housing Bearing (30) was removed, stand the Drive
Housing (27) upright and press a new Drive Housing Bearing,

indicated by the punch marks. At the same time, align the Cap
Screw holes in the Gear Case Cover and Housing.
5. Install the Drive Housing Cap Screws (23) and Lock Washers (24)
and tighten the Cap Screws to 100 in-lb (11 Nm) of torque.
Testing the Starter
1. Turn the pinion by hand in the direction of Starter rotation. The
pinion should advance smoothly and easily to the stop.
2. Turn the pinion opposite the direction of Starter rotation. The
gearing and motor should rotate freely with no binding.
3. Attach an air hose to the inlet and operate the motor slowly to
see that it functions properly and that the drive pinion rotates in
the proper direction. If the direction of rotation is incorrect, the
motor was improperly assembled.
4. The chambers on the pinion teeth should be on the following
side of the teeth.
