Underdrive Clutch Inspection

Install the underdrive clutch to the transaxle case.

NOTICE:

Be careful not to damage the oil seal rings.

Install a dial indicator as shown in the illustration.

Measure the underdrive clutch pack clearance while applying and releasing compressed air (392 kPa, 4.0 kgf/cm², 57 psi).

Standard pack clearance:

1.51 to 1.71 mm (0.0594 to 0.0673 in.)

HINT:

There are 5 different thicknesses of flanges available.

Standard flange thickness:

Mark	Thickness	Mark	Thickness
1	3.0 mm (0.118 in.)	4	3.6 mm (0.142 in.)
2	3.2 mm (0.126 in.)	5	3.8 mm (0.150 in.)
3	3.4 mm (0.134 in.)	-	-

Check if the sliding surfaces of the discs, plates and flange are worn or burnt. If necessary, replace them.

NOTICE:

1. If the lining of a disc comes off or is discolored, or if a part of the groove is worn, replace all the discs.
   
2. Before installing new discs, immerse them in ATF for at least 15 minutes.
   

Using a caliper gauge, measure the inside diameter of the underdrive clutch drum bushing.

Standard inside diameter:

37.06 to 37.08 mm (1.4591 to 1.4598 in.)

Maximum inside diameter:

37.13 mm (1.4618 in.)

Using a vernier caliper, measure the free length of the spring together with the spring seat.

Standard free length:

17.14 mm (0.6748 in.)
