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.

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.

5. If the specified preload cannot be obtained within
the specified tightening torque, adjust by select-
ing the proper adjust shims.

ing the thickness of the shims.

ASSEMBLY 7B
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.

Procedure
1. Adjust the preload of the output gear bearing and select the adjust shim(s) as described below.
Note To adjust the preload, use the SST shown below.
83U07B-367

(1) Press the bearing cover in after aligning it with
guide bolts as shown.
Tightening torque: 11—14 N-m
(110—140 cm-kg, 95—122 in-lb)
(2) Install the converter housing onto the SST.
(3) Remove the bearing outer race and adjust
shims from the bearing housing. (Refer to page
7B—185)
(4) Mount the output gear assembly onto the con-
verter housing.

(5) Install the outer race removed in step (2) to the
SST; then mount them on the output gear as-
sembly.
Caution
Eliminate the gap (arrow) by turning A or B of
the selector.
76G07B-172
(6) Set the four SST on the converter housing in
the positions shown.
76G07B-173
(7) Set the bearing housing on the SST (selector)
and install the four SST (bolts); then tighten
them to the specified torque.

(8) Turn the SST (selector) to increase the clear-
ance indicated by the arrow with the SST (bars)
until it no longer turns.
Note
This is to seat the bearing.
(9) Turn the selector in the opposite direction un-
til the preload is eliminated (gap is reduced).

(10) Mount the SST and pull scale or torque
wrench on the output gear.
(11) Increase the clearance between A and B
to obtain the specified preload/pull scale
reading.
Preload: 0.5—0.9 N-m
(5.0—9.0 cm-kg, 4.34—7.81 in-lb)
Reading on pull scale: 5—9 N
(0.5—0.9 kg, 1.1—1.98 lb)

Note
Read the preload when the output gear starts
to turn.

(12) Measure the clearance. Select adjust
shim(s) equivalent to the measured
clearance.
