MEASURE PLANETARY PINION GEAR THRUST
CLEARANCE
Using a feeler gauge, measure the planetary pinion gear
thrust clearance.
Standard clearance:
0.16±0.56 mm (0.0063±0.0220 in.)

OVERDRIVE DIRECT CLUTCH
DISASSEMBLY
1. CHECK PISTON STROKE OF DIRECT CLUTCH
Install a dial indicator and measuring terminal (SST) to-
gether, measure the piston stroke while applying and re-
leasing compressed air (392±785 kPa, 5±8 kgf/cm
2,
57±114 psi).
Piston stroke:
1.75±2.49 mm (0.0689±0.0980 in.)
SST 09350±32014 (09351±32190)
If the piston stroke is greater than the maximum, inspect
each component.
