Forward Clutch Inspection

Install the forward clutch on the oil pump.

NOTICE:

Be careful not to damage the oil seal ring of the oil pump.

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

Standard pack clearance:

1.00 to 1.25 mm (0.0394 to 0.0492 in.)

HINT:

If the opening is large, cover it with a piece of cloth to prevent compressed air from escaping.

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

Standard free length:

26.74 mm (1.0528 in.)

Check if the disc lightly rotates when rotating the forward clutch after inserting the multiple disc clutch into it.

NOTICE:

Do not place the forward clutch in a vise.
