6. CHECK PISTON STROKE OF DIRECT CLUTCH
If replacing the disc, plate or flange, check the piston stroke.
a. Install the direct clutch on the oil pump.
b. Using a dial indicator (long type pick or SST), measure the direct clutch piston stroke applying and releasing the compressed air (4 - 8
kg/sq.cm, 57 - 114 psi or 392 - 785 kPa) as shown.
SST 09350 - 32013 (09351 - 32190)
Piston stroke: 1.11 - 1.44 mm (0.0437 - 0.0567 in.)
If the piston stroke is less than the limit, parts may be misassembled and reinstall them.
If the piston stroke nonstandard, select another flange.
NOTE: There are two different flange thickness.
Flange thickness:
2.60 mm (0.1024 in.)
3.00 mm (0.1181 in.)
7. CHECK OPERATION OF DIRECT CLUTCH
Apply compressed air into the passage with the oil pump body and be sure that the piston moves.
If the piston does not move, disassemble and inspect.
INSPECTION OF DIRECT CLUTCH
1. INSPECT CLUTCH PISTON
a. Check that check ball is free by shaking the piston.
