FLYWHEEL RING GEAR MAINTENANCE (Contd)
Both flywheel ring gears are replaced the same way. This procedure
covers the replacement of one flywheel ring gear.
Do not use a steel drift pin. Failure to comply may result in damage
to ring gear and/or flywheel.
Using brass drift pin, remove flywheel ring gear (1) from flywheel (2).
Heat new ring gear (1) for 20 minutes in oven preheated to 127 C (260 F).
To reduce the possibility of severe burns, wear protective gloves
when installing the heated gear. Failure to comply may result in
injury to personnel.
The ring gear must be installed so the bevel on the teeth is toward
the crankshaft side of the flywheel. Failure to comply may result in
damage to equipment.
If experiencing difficulty installing flywheel ring gear on flywheel,
use a brass drift pin to assist with installation.
Install flywheel ring gear (1) on flywheel (2).
