around the gear to remove
it
from the flywheel.
(2) Heat the new ring gear to 250—300°C
(480—570°F), then fit it onto the flywheel.
Caution
The bevelled side of the ring gear must face
toward the engine side.
3. Runout of flywheel
(1) To measure, set a dial indicator on the clutch
disc contact surface, and turn the flywheel.
Runout: 0.2 mm (0.008 in) max.
(2) If the runout exceeds specification repair by
grinding.
