Installation

INSTALLATION





1. Apply a light coating of gear lubricant on the lip of pinion seal.
2. Install new pinion seal with Installer 8889 (1) and hammer (2).




3. Install flange on pinion shaft with the reference marks aligned.
4. Install companion flange (1) with Installer C-3718 (2).




5. Install pinion a new pinion nut.

CAUTION: Do not exceed the minimum tightening torque when installing the companion flange retaining nut at this point. Failure to follow these instructions can damage the collapsible spacer or bearings.

6. Hold companion flange (2) with Wrench C-3281 (1) and tighten pinion nut to 298 Nm (220 ft. lbs.). Rotate pinion several revolutions to ensure bearing rollers are seated.
7. Set torque wrench to 678 Nm (500 ft. lbs.) and tighten pinion nut in 6.8 Nm (5 ft. lbs.) increment until Pinion Torque To Rotate specification is achieved.




8. Measure pinion torque to rotate with an inch pound torque wrench (2). Torque To Rotating should be equal to the reading recorded during removal plus an additional 0.56 Nm (5 in. lbs.).

CAUTION: Never loosen pinion nut to decrease pinion bearing rotating torque and never exceed specified preload torque. If rotating torque is exceeded, a new collapsible spacer must be installed. Failure to follow these instructions can damage the collapsible spacer or bearings.

9. If torque to rotating is low, tighten pinion nut in 6.8 Nm (5 ft. lbs.) increments until proper rotating torque is achieved.

NOTE: The bearing rotating torque should be constant during a complete revolution of the pinion. If the rotating torque varies, this indicates a binding condition.

10. Install propeller shaft.
11. Install rear brake components.
