INSPECTION AND REPAIR
PRECAUTION
(1) Several of the parts resemble each other; organize them so that they do not get mixed up.
(2) Clean each part with cleaning oil, clean out the oil holes and oil passages with compressed air,
and check that there are no obstructions.
(3) When using cleaning oil and compressed air, wear protective eyewear.
(4) If a clutch plate or brake band is replaced with a new one, soak it in ATF for 2 hours or more
before installing.
(5) Before assembly, apply ATF to all seal rings, rotating parts, and sliding parts.
(6) All seals, gaskets and roll pins must be replaced with new ones during assembly.
(7) Use petroleum jelly, not grease where required.
(8) When it is necessary to replace a bushing, replace the assembly which includes that bushing.

TORQUE CONVERTER
The torque converter is welded together and cannot
be disassembled.
Inspection
1. Check the outer part of the converter for damage
or cracks, and replace it if necessary.
2. Check for rust on the pilot hub of the converter or
on the boss. If there is any, remove it completely.
3. Measure the bushing of the converter boss. Re-
place the converter assembly if the bushing is
worn.
Bushing inner diameter
Standard: 33.000—33.025 mm
(1.299—1.300 in)
Maximum: 33.075 mm (1.302 in)
Washing Inside of Converter
1. Drain any ATF remaining in the converter.
2. Pour in solvent [approximately 0.5 liter (0.53 US
qt, 0.44 Imp qt) ].
3. Shake the converter to clean the inside. Pour out
the solvent.
4. Clean the inside of the converter with compressed
air so that the inside is perfectly empty.
5. Pour in ATF.
6. Shake the converter to clean the inside. Pour out
the ATF.

5. If the specified preload can not be obtained with-
in the specified tightening torque, adjust it by select-
ing the proper adjust shims.
Thickness of shim
