Forward Clutch -- Inspection |
1. INSPECT PACK CLEARANCE OF FORWARD CLUTCH |
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).
- Pack clearance:
- 1.00 to 1.25 mm (0.0394 to 0.04921 in.)
If the clearance is not within the standard, inspect the discs, plates and flange.
If the piston stroke is less than the minimum, parts may have been assembled incorrectly. Check and reassemble again.
- HINT:
- As the opening is large, cover it with a piece of cloth or shop rag to prevent the compressed air from being released.
- There are 5 different thicknesses of flanges available.
Flange thickness: mm (in.)No.

2. INSPECT FORWARD MULTIPLE DISC CLUTCH DISC |
Check if the sliding surfaces of the discs, plates, and flange are worn or burnt.
If necessary, replace them.
- HINT:
- If the lining of a disc comes off or discolors, or even if a part of the groove is damaged, replace all discs.
- Before assembling new discs, soak them in ATF for at least 15 minutes.
3. INSPECT FORWARD CLUTCH RETURN SPRING SUB-ASSEMBLY |
Using vernier calipers, measure the free length of the spring together with the spring seat.
- Standard free length:
- 26.74 mm (1.0528 in.)
If the free length is shorter than the standard free length, replace the forward clutch return spring sub-assembly.
4. INSPECT FORWARD MULTIPLE DISC CLUTCH DISC |
Check if the disc lightly rotates when rotating the forward clutch assembly after inserting the multiple disc clutch into it.
- NOTICE:
- Do not place the forward clutch assembly in a vise.
