7. NOTICE: Under no circumstances is the pinion nut to be backed off to reduce drive pinion bearing preload. If reduced drive pinion
bearing preload is required, a new drive pinion collapsible spacer and pinion nut must be installed or damage to the component may
occur.
NOTICE: The color on the rear face of the drive pinion nut is critical to this repair. Use the same color new drive pinion nut for
installation. If a new collapsible spacer must be installed for pinion bearing preload reduction, install the nut supplied with the new
spacer or damage to the component may occur.
NOTE: Remove the Drive Pinion Flange Holding Fixture while taking drive pinion bearing preload readings with the Nm (lb-in) torque wrench.
Using the Drive Pinion Flange Holding Fixture to hold the pinion flange, tighten the pinion nut.
-
Rotate the drive pinion occasionally to make sure the drive pinion bearings are seating correctly.
-
Install a Nm (lb-in) torque wrench on the pinion nut.
-
Rotating the drive pinion through several revolutions, take frequent drive pinion bearing preload readings until the original recorded drive
pinion bearing preload reading is obtained.
-
If the original recorded drive pinion bearing preload is lower than specifications, tighten to the appropriate specifications for used drive pinion
bearings. If the drive pinion bearing preload is higher than specification, tighten the pinion nut to the original reading as recorded. For
additional information, refer to Specifications.
8. Install the driveshaft. For additional information, refer to Drive/Propeller Shafts, Bearings and Joints.
9. Install the brake disc. For additional information, refer to Disc Brake System.
