COMPONENT PARTS
GENERAL NOTES
The instructions here are organized so that you work on only one component group at a time.
This will help avoid confusion from similar±looking parts of different subassemblies being on your work-
bench at the same time.
The component groups are inspected and repaired from the converter housing side.
As much as possible, complete the inspection, repair and assembly before proceeding to the next com-
ponent group. If a component group cannot be assembled because parts are being ordered, be sure
to keep all parts of that group in a separate container while proceeding with disassembly, inspection,
repair and assembly of other component groups.
Recommended fluid for the automatic transaxle:
DEXRON ® @@@@@: [g 2]
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean and any fluid passages and holes blown through with
compressed air.
2. When using compressed air to dry parts, always aim away from yourself to prevent accidentally spray-
ing automatic transmission fluid or kerosene in your face.
3. The recommended automatic transaxle fluid or kerosene should be used for cleaning.
PARTS ARRANGEMENT:
1. After cleaning, the parts should be arranged in the correct order to allow efficient inspection, repairs,
and reassembly.
2. When disassembling a valve body, be sure to keep each valve together with the corresponding spring.
3. New brakes and clutches that are to be used for replacement must be soaked in transaxle fluid for at
least 15 minutes before assembly.
GENERAL ASSEMBLY:
1. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with
transmission fluid prior to reassembly.
2. All gaskets and rubber O±rings should be replaced.
3. Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installed in the
groove correctly.
4. If a worn bushing is to be replaced, the subassembly containing that bushing must be replaced.
5. Check thrust bearings and races for wear or damage. Replace if necessary.
6. Use petroleum jelly to keep parts in place.

SECOND COAST BRAKE INSPECTION
INSPECT BRAKE BAND
If the lining of the brake band is peeling off or discolored,
or even if a part of the printed numbers are defaced, re-
place the brake band.
SECOND COAST BRAKE PISTON
ASSEMBLY
1. SELECT PISTON ROD
If the band is OK, but the piston stroke is not within the
standard value, select a new piston rod.
Piston stroke:
1.5 ± 3.0 mm (0.059 ± 0.118 in.)
There are 2 lengths of piston rod.
Piston rod length:
72.9 mm (2.870 in.)
71.4 mm (2.811 in.)
2. INSTALL PISTON ROD
(a) Install the washer and spring to the piston rod.
(b) Install an E±ring while pushing the piston.

If the inside diameter is greater than the maximum, re-
place the flange.
