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.

(7) Turn the SST (selector) to increase the clear-
ance indicated by the arrow with the SST
(bars), until it no longer turns.
Note
a) This is to seat the bearings.
b) To turn the SST (B), bend the bar as shown.
(8) Turn the selector in the opposite direction un-
til the preload is eliminated (gap is reduced).
(9) Insert the SST through the oil seal hole of the
transaxle case and attach it to the pinion shaft.
(10) Mount the SST and pull scale or torque
wrench.
(11) Widen the clearance between A and B to ob-
tain the specified preload/pull scale reading.
Preload:
0.5 N-m (5 cm-kg, 4.3 in-lb)
Reading on pull scale:
5 N (0.5 kg, 1.1 lb)
Note
Read the preload when the differential starts
to turn.
(12) Measure the clearance between A and B.
(13) Add 0.3 mm (0.0118 in) to the measured
clearance, and select the shim(s) closest in
valve to that measurement.
