Figure 14— Pinion Depth Tools
4. Install J 21777-40, J 21777-42, J 21777-43, and
J 23597-11 to the pinion bore (figure 14).
NOTICE: Refer to “Notice” on page 4B1-1.
5. Hold the stud stationary at the flats of the stud.
Tighten
&
• Stud nut to 2.2 N-m (20 lbs. in.).
6. Rotate the gage plate and bearings several com
plete revolutions to seat the bearings.
7. Tighten the stud nut until a torque of 1.6 to 2.2 N-m
(15 to 25 lbs. in.) is obtained to keep the gage
plate in rotation.
8. Assemble J 21777-45, J 23597-11, and J 8001 to
the differential bearing bores as shown in figure 14.
• The bearing bores must be clean and burr free.
9. Install the side bearing caps and tighten the bolts
finger tight.
10. Rotate the gage plate until the gaging areas are
parallel with the discs.
11. Position the gage shaft assembly in the carrier so
that the dial indicator rod is centered on the gage
area of the gage block.
12. Set the dial indicator at zero. Push the indicator
down on the indicator shaft until the needle rotates
approximately 3/4 of a turn clockwise. Tighten the
dial indicator in this position.
13. Rotate the gage shaft slowly back and forth until
the dial indicator reads the greatest deflection. This
is when the indicator needle is centered between
moving to the left and to the right.
14. At the point of greatest deflection, set the dial indi
cator to zero. Repeat the rocking action of the
gage shaft to verify the zero setting.
15. Rotate the gage shaft until the dial indicator rod
does not touch the gage block.
16. Record the actual number on the dial indicator and
not the number that represents how far the needle
travels. This is the nominal pinion setting.
EXAMPLE: If the indicator needle moved coun
terclockwise 1.70 mm (0.067 inch) to a dial reading
of 0.84 mm (0.033 inch) as shown in figure 15,
record the dial reading of 0.84 mm (0.033 inch)
NOT 1.70 mm (0.067 inch). The dial indicator
should be in the 0.50 to 1.27 mm (0.020 to 0.050
inch) range.
17. All drive pinion gears are manufactured to a nomi
nal depth. There are no markings on the pinion for
depth. Dial indicator reading is the shim selection.
18. Remove bearing caps and depth gaging tools.
19. Install the correct pinion shim to the pinion.

Differential Side Bearing Installer
J

Driver Handle
J
8107-2
D ifferential Side Bearing Remover
Plug
1. Lubricate all parts with axle lubricant.
2.
Thrust washers to the side gears.
3. Side gears to the differential case.
• Install the side gears on the same side as
removed.
4. Pinion gears to the differential without the thrust
washers.
A. Place one pinion gear on the side gear and
rotate the gear until the pinion is exactly oppo
site from the differential opening.
B. Place the second pinion gear on the side gear
so the pinion gear holes line up.
C. Rotate the pinion gears into place, and verify
the pinion gears line up with the pinion shaft
holes.
5.
Pinion thrust washers.
• Rotate the pinion gears toward the differential
opening enough to slide in the pinion thrust
washers.
6. Pinion shaft.
7.
Pinion shaft lock bolt.
• Check that the mating surfaces of the differen
tial case and the ring gear are clean and burr
free.
8.
Ring gear to the differential case (figure
16).
A. Install two threaded studs into the ring gear on
opposite sides.
B. Place the ring gear on the case and align the
studs with the holes in the case.
NOTICE: Refer to "Notice" on page 4B1-1.
9.
Ring gear bolts.
• Tighten the ring gear bolts alternately and in
stages, gradually pulling the ring gear onto the
differential case.
• The ring gear bolts in sequence to 120 N-m (90
lbs. ft.).
