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

Preload:
0.03—0.9 N-m

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.

is 7.
b) Preload is reduced by increasing the thick-
ness of the shims, or increased by reduc-
ing the thickness of the shims.

ASSEMBLY
PRECAUTION
(1) The automatic transaxle consists of high-precision-finished parts, necessitating careful inspection
before assembly because even a small nick could cause fluid leakage or affect performance.
(2) Clean out oil holes and oil passages with compressed air, and check that there are no obstructions.
(3) Before assembly, apply ATF to each O-ring, seal ring, rotating part, and friction part.
(4) If the brake band or drive plates are replaced with new ones, first soak them in ATF for at least
2 hours before installing.
(5) Each seal gasket and O-ring must be replaced with a new one.
(6) Be sure to install all thrust bearings and races in the correct direction and position.
