INSPECT PACK CLEARANCE OF DIRECT CLUTCH

Install the direct clutch on the transaxle rear cover.

Using a dial indicator, measure the direct clutch pack clearance while applying and releasing compressed air (392 kPa, 4.0 kgf/cm² , 57 psi).

Standard pack clearance: 0.605 to 0.825 mm (0.02382 to 0.03248 in.)

If the pack clearance is less than the minimum, parts may have been assembled incorrectly, so check and reassemble again.

If the stroke is not as specified, select another flange.

HINT:

There are 6 flanges in different thickness.
