ASSEMBLY
9. Remove converter housing from transmission case.
10. Remove final drive assembly from transmission case.
11. Remove differential side bearing outer race from transmission
case.
12. Reinstall differential side bearing outer race and shim(s)
selected from SDS table on transmission case.
13. Reinstall converter housing on transmission case and tighten
transmission case fixing bolts to the specified torque. Refer to
AT-461, "
OVERHAUL".
14. Insert Tool and measure turning torque of final drive assembly.
lTurn final drive assembly in both directions several times
to seat bearing rollers correctly.
lWhen old bearing is used again, turning torque will be
slightly less than the above.
lMake sure torque is close to the specified range.
REDUCTION PINION GEAR BEARING PRELOAD
1. Remove transmission case and final drive assembly from con-
verter housing.
2. Select proper thickness of reduction pinion gear bearing adjust-
ing shim using the following procedures.
a. Place reduction pinion gear on transmission case as shown.
b. Place idler gear bearing on transmission case.
c. Measure dimensions “B” “C” and “D” and calculate dimension
“A”.

PREPARATION
HFC-134a (R-134a) Service Tools and Equipment
EJS000TB
Never mix HFC-134a refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or its lubri-
cant.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/lubri-
cant.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor failure will result.

TROUBLE DIAGNOSIS
CHECKING BLOEWER
1. Press fan switch (up side) one time.Blower should operate on
low speed.The fan symbol should have one blade lit .
2. Press fan switch (up side) one more time, and continue check-
ing blower speed and fan symbol until all speeds are checked.
3. Leave blower on MAX speed.
If NG, go to trouble diagnosis procedure for blower motorAT C - 6 7
.
If OK, continue with next check.
CHECKING DISCHARGE AIR
1. Press mode switch four times and DEF button.
2. Each position indicator should change shape.
3. Confirm that discharge air comes out according to the air distri-
bution table.Refer to Discharge Air FlowAT C - 2 8
.
Intake door position is checked in the next step.
If NG, go to trouble diagnosis procedure for intake door motorAT C -
64.
If OK, continue with next check.
NOTE:
Confirm that the compressor clutch is engaged (visual inspection)
and intake door position is at FRESH when the DEF is selected.
CHECKING RECIRCULATION
1. Press recirculation (REC) switch one time. Recirculation indica-
tor should illuminate.
2. Listen for intake door position change (you should hear blower
sound change slightly).
If NG, go to trouble diagnosis procedure for intake motor doorAT C -
64.
If OK, continue with next check.
