Forward Clutch

A245E AUTOMATIC TRANSAXLE: FORWARD CLUTCH: INSPECTION

INSPECTION

1. INSPECT PISTON STROKE OF FORWARD CLUTCH





(a) Using a dial indicator (long type pick or SST), measure the forward clutch piston stroke while applying and releasing compressed air (392 to 785 kPa, 4 to 8 kgf*cm2, 57 to 114 psi).
SST: 09350-32014
09351-32190
Piston stroke:
1.41 to 1.81 mm (0.0555 to 0.0713 in.)
If the piston stroke is non-standard, select another flange.

HINT: There are 5 different thickness for the flange.





2. INSPECT FORWARD CLUTCH PISTON SUB-ASSEMBLY





(a) Check that the check ball is free by shaking the forward clutch piston sub-assembly.
(b) Check that the valve does not leak by applying low-pressure compressed air.
3. INSPECT FORWARD MULTIPLE DISC CLUTCH DISC





(a) Check if the sliding surfaces of the discs, plates and flanges are worn or burnt. If necessary, replace them.

- If the lining of the disc is peeling off or discolored, or even if a part of the printed numbers are defaced, replace all discs.
- Before assembling new discs, soak them in ATF for at least 15 minutes.
