follows:

(Caution: Do not heat the ring gear to a

bright red as heat-treatment will be destroyed.

(a) Heat the ring gear uniformly to ap-

proximateIy) 400F (red heat visible in the dark).

Keep the flywheel at room temperature.

(b) Start the ring gear on the flywheel (3) so

the chamfered ends of the teeth are facing the

cylinder block. These ends of the teeth engage with

the drive pinion of the starter motor.

(c) Drive the ring gear down tight against

the shoulder of the flywheel. Allow the ring gear to

cool slowly. do not cool with water.

(2) Install the wear sleeve (4) as follows:

(a) Position the wear sleeve so its beveled

edge is in the same direction as the beveled edge of

the flywheel.
