Direct Clutch

U151F AUTOMATIC TRANSAXLE: DIRECT CLUTCH: INSPECTION

INSPECTION

1. INSPECT PACK CLEARANCE OF REVERSE CLUTCH






(a) Install the intermediate shaft and needle roller bearing onto the transaxle rear cover.
(b) Using a dial indicator, measure the reverse clutch pack clearance while applying and releasing compressed air (392 kPa, 4.0 kgf/cm2, 57 psi).
Pack clearance:
0.60 to 0.82 mm (0.0236 to 0.0323 in.)
If the pack clearance is not as specified, inspect the discs, plates, and flange.
2. 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 (0.0240 to 0.0327 in.)
If the pack clearance is not as specified, inspect the discs, plates, and flange.
3. INSPECT DIRECT MULTIPLE CLUTCH DISC






(a) Check if the sliding surfaces of the disc, plate, and flange are worn or burnt.
If necessary, replace them.
HINT:
- If the lining of the disc comes off or discolors, or if a part of the groove is worn, replace all discs.
- Before installing new discs, immerse them in ATF for at least 15 minutes.

4. INSPECT OVERDRIVE DIRECT CLUTCH DISC






(a) Check if the sliding surface of the disc, plate, and flange are worn or burnt.
If necessary, replace them.
HINT:
- If the lining of the disc comes off or discolors, or if a part of the groove is worn, replace all discs.
- Before installing new discs, immerse them in ATF for at least 15 minutes.

5. INSPECT OVERDRIVE CLUTCH RETURN SPRING SUB-ASSEMBLY






(a) Using vernier calipers, measure the free length of the spring together with the spring seat.
Standard free length:
25.91 mm (1.0201 in.)
If the result is not as specified, replace the spring.
6. 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 (0.0236 to 0.0323 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 different thicknesses of flanges available.

Flange thickness: mm (in.)





7. 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).
Clearance:
0.61 to 0.83 mm (0.0240 to 0.0323 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 different thicknesses of flanges available.

Flange thickness: mm (in.)









(b) Check that the disc rotates when rotating the disc after inserting the rear planetary sun gear.
NOTE: Do not place the rear planetary sun gear in a vise.
If the result is not as specified, replace the rear planetary sun gear.
