If the flywheel ring gear has damage, a replace-
ment can be made as follows:
a) Heat the ring gear to a maximum (empera-
ture of 320°C (608°F) and install it on the
flywheel so the chamfer of the gear teeth
will be toward the starter pinion when the
flywheel is installed.

guide bolts (3) in the crankshaft.
Fasten strap (1) and a hoist to flywheel (2) and
