NOTE: If a press is not available proceed to point 18 and fit the
flange.
CAUTION:
When using a press to fit the outer bearing cone on the
pinion always support the pinion head with a suitable block
of wood (Fig. 2.28). Failure to do this could result in damage
to the carrier casting or drive gear assembly.
18. Fit the flange and tighten the pinion nut to a torque value of
1350 - 1670Nm.
NOTE: The flange must be fully seated against the outer pinion
bearing before the nut is tightened to the torque specification.
The flange must be held with a suitable tool (CT03) to tighten the
nut and a torque multiplier will be required to achieve the correct
t
orque value of 1350 - 1670 Nm. (Fig.2.29)

19. Check the bearing preload, it should be 0.5-10Nm (Fig.2.30).
If the preload (torque) of the pinion bearing is not within
0.5 -10 Nm, remove the pinion from the carrier and follow
the appropriate procedure (see steps 14-19) and below
instructions:
• To increase preload:
decrease the bearing spacer combination.
• To decrease preload:
increase the bearing spacer combination.
