7. NOTE: Also refer to the illustration.
Adjust the pinion bearing preload by replacing the pinion bearing preload spacer.
^
To increase the preload, install a thinner spacer. To decrease the preload, install a thicker spacer.
^
The pinion bearing preload spacers are available in sizes from 7.26 to 8.00 mm (0.286 to 0.315 inch).
^
Always measure the replacement spacer before installing it.
^
On a flat surface, sand the next thicker size spacer with emery cloth to the desired thickness to obtain a closer adjustment. Thoroughly wash the
spacer to remove the emery cuttings before installation.
^
A 0.0254 mm (0.001 inch) change in the spacer thickness will change the torque rate approximately 3.3894 Nm (30 inch lbs.).
^
Repeat Steps 6 and 7 of this procedure until the rotational torque is within specifications.
