AUTOMATIC TRANSMISSION AND DIFFERENTIAL
b. The center support is engaged with
the transmission case by splines at
one p()sition. When installing the
center support, be careful not to
damage the one way clutch and
bushing by the end of the center
support.
c. Install the snap ring (134 mm) with
its open ends positioned sideward
or upward.
d. If difficulty is encountered in in·
stalling the center support, loosen
the bolt that fixes the transmission
case to stand.
8) Measuring the clearance between
piston 2 and driven plate
After assembly, measure the clearance
between piston 2 and driven plate. The
clearance should be within the specifi·
cations.
Low &
0.50 - 1.20 mm
reverse brake
(0.0197 - 0.0472 in)
clearance
9) Checking the operation of low
&
reverse brake
Apply air into the oil hole in low
&
reverse brake to see that the piston
moves properly.
10) Installation of connecting shell
and clutch hub
Install connecting shell and clutch hub
as an ASSY to the spline of reverse sun
gear and forward sun gear.
11) Installation of forward clutch
ASSY and reverse clutch ASSY
Install forward clutch ASSY and
reverse clutch ASSY in that order.
Make certain that th.e thickness of
washer which is installed between
forward clutch ASSY and clutch hub
is 1.2 mm (0.047 in).
12) Installation of brake band
Match the projected portions of the
brake band with the knotches in the
transmission case to install the brake
band.
NOTE:
When handling the brake band, be
careful not to open its open end too
much.
Too much opening causes separation
and damage of the facing.
13) Measure the total end play in the
axial direction. Determine the thick·
ness of the washer (21x31.2xt) to be
used at the oil pump carrier end.
The total end play should be within
specifications.

a. Measure dimension "L", as shown,
using Depth Gauge 498147001 and
Low & Reverse Brake Gauge
398643600.
NOTE:
When measuring dimension "L",
ensure that the thrust bearing
(20x35x2.8) is not installed.

14) Measure the end play of the
reverse clutch drum.
Select a suitable thrust front clutch
washer so that the end play between
the reverse clutch drum and oil pump
carrier is within specifications.
