If the pack clearance is not as specified, inspect the discs, plates and flange.

2. Inspect pack clearance of direct clutch and overdrive clutch

 Inspect pack clearance of direct clutch and overdrive clutch

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

Pack clearance: 0.61 to 0.83 mm (0.02401 to 0.03268 in.)

If the pack clearance is not as specified, inspect the discs, plates and flange.

3. INSPECT DIRECT MULTIPLE DISC CLUTCH DISC

6. INSPECT PACK CLEARANCE OF REVERSE CLUTCH

INSPECT PACK CLEARANCE OF REVERSE CLUTCH

(a) Install the intermediate shaft onto the transaxle rear cover.

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

Clearance: 0.60 to 0.82 mm (0.02362 to 0.03228 in.)

If the pack clearance is less than the minimum, parts may have been assembled incorrectly, so check and reassemble again. If the clearance is not as specified, select another flange.

HINT: There are 7 flanges of different thickness.

Flange thickness: mm (in.)

7. INSPECT PACK CLEARANCE OF DIRECT CLUTCH AND OVERDRIVE CLUTCH

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

psi).

Clearance: 0.61 to 0.83 mm (0.02401 to 0.03268 in.)

If the pack clearance is less than the minimum, parts may have been assembled incorrectly, so check and reassemble again. If the clearance is not as specified, select another flange.
