sure the head of preload screw (Item 2) aligns with the
counter bore of the plate. Apply serviceable thread
locking compound to screws (Item 3) and torque to
17.5 Nm.
9. Seat the pinion by rotating the preload screw
counterclockwise unil the pinion first makes solid
contact with the gear. Do not apply excessive torque
on the screw. It should be finger tight at this point.

frame or PRD mounting plate, and locate its probe on
the OD of the pinion flange such that it measures in
the direction of preload travel.
11. Apply the preload of 0.010 – 0.015 mm by turning
the preload screw (Item 2) counterclockwise. Once
preload is set tighten the preload bolts (Item 1) to 40
Nm. Watch the dial indicator as the preload is set as
it may move. If any changes are witnessed, remove the
preload and repeat procedure.
