18. Check the rolling torque of the pinion as shown.
It must be 0.85 to 1.70 NIm (7.5 to 15.0 lbIin). If
the rolling torque is not correct, add or remove
shims (23) until it is correct. Removal of shims
(23) increases rolling torque. Adding shims (23)
decreases the rolling torque. Record the actual
rolling torque after the shims have been added or
removed. Do not put the cap over the pinion nut
yet.

19. If bearing cones (5) were removed, heat them to
135°C (275°F), and install them on the carrier.
Put the thrust washers and axle gears (9) in
position in the carrier.
20. Install the thrust washers, side gears (7) and pin
(8). Install roll pin (6) through the carrier and pin
(8).

21. Put bevel gear (4) on the carrier and the ten
bolts. Tighten the bolts to a torque of 70 L 15
NIm (50 L 11 lbIft). Put bearing cups (3) on the
bearing cones.

22. Put the carrier assembly in position in the
9
housing assembly. Install bearing caps (1) and
the four bolts. Tighten the bolts to a torque of 220
L 25 NIm (160 L 18 lbIft).
23. Install the lockwasher and locknuts (2). Install
tooling (F) as shown, and adjust locknuts (2) with
tooling (A) until there is a backlash of 0.13 to
0.20 mm (.005 to .008 in). To adjust backlash,
turn one locknut in and the other one out the
same amount of turns.
24. Check the rolling torque again as shown in step
18. Tighten locknuts (2) with tooling (A) equally to
preload the bearings. Proper bearing preload will
increase the recorded preload in Step 18 by 0.63
to 0.88 NIm (5.6 L 7.8 lbIin).
25. Measure backlash again. Bend a tab from each
lockwasher into a slot of locknuts (2) to hold
them in position.
