on the pinion gear and align them with the pinion
shaft hole.
7. Set the steel ball in the hole in the gear case.
Note
Affix the ball with petroleum jelly.
8. Install the governor drive gear onto the gear case
with a plastic hammer.
9. Install the snap ring.
10. Check and adjust the backlash of the side gears
and pinion gears as follows:
(1) Install the left and right driveshafts in the
differential assembly.
(2) Support the driveshafts on V-blocks.
(3) Measure the backlash of both pinion gears.
Backlash:
Standard 0.025—0.1 mm (0.001—0.004 in)
Maximum 0.5 mm (0.020 in)
11. If the backlash is not within specification, replace
the differential assembly.

INSPECTION AND REPAIR 7B
Inspection
Check the following and replace any faulty parts.
1. Damaged or worn idle gear
2. Damaged or worn bearing
86U07B-340
Assembly
1. Press the bearing outer races in with the SST.
86U07B-341
86U07B-342
2. Install the idle gear bearing onto the idle shaft, then
install the idle gear, adjust shim, spacer, and
bearing.
3. Secure the idle shaft in a vise with the SST; then
tighten the locknut to the lower limit of the tighten-
ing torque.
Tightening torque:
128 N-m (13 m-kg, 94 ft-lb)
Note
Use the protective plates to prevent damage
to the SST.

4. Check and adjust the idle gear bearing preload.
(1) Turn the idle gear assembly and SST over, and
secure the gear in the vice.
Note
Use protective plates to prevent damage to
the idle gear.
(2) Attach the SST and spring scale or torque
wrench, and measure the preload while tight-
ening the locknut.
Tightening torque:
128—177
N m
(13—18 m-kg, 94—130 ft-lb)
49FT01 439
Preload:
0.03—0.9 N-m
(0.3—9.0 cm-kg, 0.26—7.8 in-lb)
Value indicated on pull scale:
0.3—9 N (0.03—0.9 kg, 0.066—1.98 lb)
Note
Read the preload when the idle shaft starts to
turn.
86U07B-345
86U07B-346
5. If the specified preload cannot be obtained within
the specified tightening torque, adjust by select-
ing the proper adjust shims.

Note
a) The maximum allowable number of shims
is 7.
b) Preload is reduced by increasing the thick-
ness of the shims, or increased by reduc-
ing the thickness of the shims.
