/37. Attach the special tool to the center support, and holding
the tool, slowly insert the center support into the case.
mCaution
Be sure that the wave spring is not out of position.
LP38. Remove the special tool from center support.
39. Fit the snap ring which retains the center support.
At this time, take care to prevent the end of the snap ring
from interfering with the pulse generator mounting hole.
40. Install the anchor rod to transaxle case.
41. Assemble a new seal ring (large diameter) and D-ring (smalldiameter) to the kickdown servo piston, and install a new
O-ring in the groove around the sleeve; then assemble thekickdown servo spring, piston and sleeve in the transaxle
case.
42. Press the kickdown servo and sleeve in by using the valve
spring compressor and special tool, and then install the
snap ring.

AUTOMATIC TRANSAXLE - Transaxle Assembly 21-25143. Install kickdown band; attach the ends of band to the ends
of anchor rod and servo piston rod.
44. Putting the kickdown drum into the kickdown band, align
the spline of the drum to that of the reverse sun gear. Placekickdown band on kickdown drum and tighten kickdown
servo adjusting screw to keep band in position.
45. Apply a coating of petrolatum to thrust bearing
#8, and
then attach to the kickdown drum.
46. Apply a coating of petrolatum to thrust race
#7, and then
attach to the rear clutch hub.
47. Install clutch hub to sun gear splines.

53. If end play which was measured and recorded at disassem-
bly is not standard value, adjust end play to specification byselecting thrust race
#3.Standard value
:0.3-1.0 mm (.012-.040 in.)
54. Attach the reused thrust washer
#I, or the one selected in
step 51 to the front clutch by using petrolatum.
55. Install special tool to the case.
56. Attach the reused thrust race
#3 or the one selected in
step 53 to the oil pump by using petrolatum.
57. Install new oil pump gasket and the oil pump assembly.

220004858. Install new O-ring in groove of oil pump housing and apply
automatic transmission fluid lightly to outside surface of
O-ring.e59. Install oil pump assembly by tightening six bolts evenly.
i-When installing this oil pump assembly, be careful that
thrust washer will not drop.
60. Check input shaft end play. Readjust if necessary (see step
53).Standard value
: 0.3-1.0 mm (.012-,040 in.)
61, Apply solder [length approx. 10 mm (40 in.) and diameter
1.6 mm (.06 in.) to the differential assembly at the locationsshown in the illustration.
“I
-4--J62. Install the converter housing without gasket.
Caution
Don’t reuse the rubber coated metal gasket which has
been used once.
63. Tighten bolts to specification.
64. Loosen the bolts and remove the converter housing in
order to remove the pieces of solder. If the solder is not
broken, carry out the work in steps (61) to (64) with large
diameter solder.
65. Using a micrometer, measure the thickness of the flattned
solder.Select the spacer in the following manner according to
measurement.Add the thickness
[0.38 mm (015 in.)] of the rubber coated
metal gasket and the end play
LO-O.1 5 mm (O-.006 in.)] ofi4the differential case to the measurement
(T). Select a -spacer which is in the calculated range, In other words,
select a spacer whose thickness is in the range of n+ 0.38mm
(.015 in.)] to [T+ 0.38 mm (.015 in.) - 0.15 mm (.006
in.)].

IThrust \\I72. Install the end clutch hub to end clutch.73. Attach, by petrolatum, thrust bearing # 13 to the end clutch
hub.74. Install end clutch assembly.
75. Install a new O-ring in the grooves of the end clutch cover.
Caution1. Install so that the O-ring is not twisted.
2. Apply
a sufficient amount of automatic transmission
fluid to the bearing.
76. Attach the end cover and fasten it with four bolts.
Caution
When installing the end cover, be sure the screw hole iscorrectly aligned. If the end cover is turned (after it is
installed) in order to align with the screw hole, the
iiO-ring may be twisted as a result.
