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.

-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.)].

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.

DISASSEMBLYN21WMCaution
%T1. Since the automatic transaxle is made of particularly
~_,high precision parts, be very careful when handling
them during disassembly and reassembly so that they
are not scratched.
2. Spread a rubber mat on the workbench and keep it
clean.3. Do not use cotton gloves or cloth rags during dis-
assembly. If they are needed, use nylon cloth or paper
towels.
4. Clean all disassembled parts. Clean metal
parts with
normal cleanser and completely dry with air.
5. Clean the clutch disc, resin thrust plate and rubber
parts with ATF (automatic transmission fluid) and do
not get any dirt on them.
6. If the transaxle itself is damaged, disassemble and
clean the cooler system also.
1. Remove the torque converter.
2. Mount the dial gauge on the transaxle case and measure
the end play of the input shaft.
3. Remove the brackets.
4. Remove the oil level gauge and oil level gauge guide.
1:5. Remove the pulse generator A and B.
6.First remove the manual control lever and then remove theinhibitor switch.
7. Remove the speedometer driven gear assembly.

21-298 AUTOMATIC TRANSAXLE - Transaxle Assembly 91. Insert the center shaft and hit it with a plastic hammer or
similar instrument to install it securely
.
NOTEApply ATF to the oil seal lip and do not scratch it.
92. Apply ATF to the oil pump drive hub, install the torque
converter and push it in securely so dimension A shown in
the figure reaches the standard value.
Standard value: Approximately 16.3 mm
(.642 in.)
CAUTIONS DURING COMPONENT DISASSEM-
BLY AND REASSEMBLYGeneral cautions when cleaning
1. Clean each part, blow out oil passages and oil holes, etc.
with air and check that nothing is clogged.
2. For cleaning fluid, use the designated ATF (automatic
transmission fluid) or kerosene.3. When drying parts with air, be careful not to get ATF or
kerosene on your face.Cautions when handling parts
1. After washing the parts, arrange them in order so inspec-
tion, repairs and assembly can be performed properly.
2. When disassembling the valve body, store each valve,
making a group of the various springs.
3.Soak the new brake and clutch discs used for replacementin ATF for more than 2 hours before assembly.
General cautions during reassembly
1.Be sure to apply ATF to seal rings, clutch disc, clutch plateand rotating parts and sliding parts and then install.
2.Replace all gaskets and O-ring with new ones and do not
reuse the old ones.
3.Use petrolatum to hold the parts in their specified places.

DISC/P. CLUTCH REACTION PLATE
(1) Assemble the clutch pressure plate, clutch plate and
clutch reaction plate, arranging them by the missing
tooth [See figure
@I.
NOTEThis is so the automatic transmission fluid escapes
easily and there is good cooling of the plate and disc.
(2) Assembly the plates so the beveled side is as shown inthe figure.
(3) Assemble so the thickest plate (clutch reaction plate) is
on the snap ring side.
1.SELECTION OF SNAP RING
Check clearance between the snap ring and clutch reaction
plate. To check the clearance, hold entire circumference ofthe clutch reaction plate down with 50
N (11 Ibs.) force. If
clearance is out of standard value, select a snap ring to
obtain the standard value.
Standard value:
0.7-0.9 mm (.028-.035 in;)
0.8-1.0 mm (.032-.039 in.)
