The gear should not be pressed or driven

on the case, as this would cause excessive

metal particles to lodge between the gear

and case, thus resulting in gear run-out.

Proper installation should, therefore,

incorporate preheating the gear to assure

correct interference fit and to eliminate

metal pickup.

(1)

Heat the ring gear in oil to approximately 160°F-180°F for about ten minutes before

assembly.

(2)

Install fourteen bolts, washers, and nuts. Torque to 180-230 Ib-ft (244-312 N·m).
