INSTALLATION

1. Apply a light coating of gear lubricant on the lip of pinion seal. Install seal with Installer 8681 (1) and Handle C-4171 (2).

2. Install flange on the pinion shaft with the reference marks aligned.
3. Install flange (1) with Installer 8112 (2) and Cup 8109.

4. Install new pinion nut.
5. Hold pinion flange (1) with Flange Wrench C-3281 (2) and tighten pinion nut to 217 Nm (160 ft. lbs.).

6. Measure pinion torque to rotating (1) with an inch pound torque wrench (2). With a torque wrench set at 542 Nm (400 ft. lbs.) tighten nut in 6.8 Nm (5 ft. lbs.) increments until pinion torque to rotating is achieved. Pinion torque to rotating is, the recorded reading plus an additional 0.56 Nm (5 in. lbs.).

CAUTION: If maximum tightening torque of 542 Nm (400 ft. lbs.) is reached before torque to rotate is achieved, the collapsible spacer may have been damaged. Never loosen pinion gear nut to decrease pinion gear bearing rotating torque and never exceed specified preload torque. Failure to follow these instruction may result in damage.

7. Install propeller shaft.
8. Install brake components.
