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).

Pack clearance:

1.51 to 1.71 mm (0.0594 to 0.0673 in.)

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

HINT:

1. If the lining of a disc comes off or discolors, or even if a part of the groove is damaged, replace all discs.
   
2. Before assembling new discs, soak them in ATF for at least 15 minutes.
   

Using a dial indicator, measure the inside diameter of the underdrive clutch drum bushing.

Standard inside diameter:

32.56 to 32.58 mm (1.2818 to 1.2826 in.)

Maximum inside diameter:

32.63 mm (1.2846 in.)

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

Standard free length:

17.14 mm (0.6748 in.)
