4. Install the yoke firmly to the differential case half
(figure 14).
5. Loosen the nut, and index one pinion gear tooth to
point downward (perpendicular to the case half
face). Tighten the nut to specifications.
6. Mount a dial indicator on the case half face using a
magnetic base (figure 15).
7. Place the stem of the dial indicator on the pinion
gear tooth.
8. Pull the pinion gear firmly into its seat, and rotate
the gear back and forth while reading the dial indi
cator. Record the reading.
• Do not unseat the pinion yoke. This will make
the backlash reading inaccurate.
9. Repeat steps 5 through 8 on the remaining 2 pin
ions.
10. The backlash should be between 0.254 and 0.457
mm (0.010 and 0.018 inch).
11. If the backlash is too high, use a thicker side gear
thrust washer.
12. If the backlash is too low, use a thinner side gear
thrust washer.
Left Side Gear Backlash Adjustment
1. Assemble the clutch plates.
• Alternate the plates as shown in figure 12.
2. Assemble the guide clips (47) to the plates.
• Use grease in the clips to hold them in place on
the plates.
3. Install the side gear thrust washer (45), clutch plate
assembly (44), and left side gear to the differential.
4. Clamp the side gear in place using a set of wash
ers, a nut, and a bolt long enough to hold the side
gear in place (figure 13).
5. Place the pinion gears and pinion thrust washers
on the pinion yoke.
6. Install the yoke firmly to the differential case half.
7. Loosen the nut and index one pinion gear tooth to
point downward (perpendicular to the case half
face). Tighten the nut.
8. Mount a dial indicator on the case half face using a
magnetic base (figure 15).
9. Place the stem of the dial indicator on the pinion
gear tooth.
10. Pull the pinion gear firmly into its seat, and rotate
the gear back and forth while reading the dial indi
cator. Record the reading.
• Do not unseat the pinion yoke. This will make
the backlash reading inaccurate.
11. Repeat steps 7 through 10 on the other 2 pinions.
12. The backlash should be between 0.051 and 0.254
mm (0.002 and 0.010 inch).
13. If the backlash is too high, use a thicker pinion
thrust washer.
14. If the backlash is too low, use at thinner pinion
thrust washer.
Reaction Block Clearance Adjustment
-►+
Install or Connect (Figures 16 and 17)
1. Left side gear thrust washer, clutch plates, and side
gear. Bolt them into position. Refer to “ Left Side
Gear Backlash Adjustment.”
2. Right side gear thrust washer and cam assembly.
Bolt them into position. Refer to “ Right Side Gear
Backlash Adjustment.”
