Forward Clutch -- Inspection |
1. INSPECT PISTON STROKE OF FORWARD CLUTCH |
Using SST and a dial indicator, measure the direct clutch piston stroke while applying and releasing compressed air (392 kPa (4.0 kgf/cm2, 57 psi)).
- SST
- 09350-30020(09350-06120)
- Piston thickness:
- 0.60 to 1.00 mm (0.024 to 0.039 in.)
If the piston stroke is not as specified, parts may have been assembled incorrectly. Check and reassemble again.
- HINT:
- If the piston stroke is still not as specified, select another flange.
- There are 8 different flange thicknesses.
- Piston stroke:
No.
| Thickness
| No.
| Thickness
|
90
| 3.0 mm (0.118 in.)
| 94
| 3.8 mm (0.150 in.)
|
91
| 3.2 mm (0.126 in.)
| 95
| 4.0 mm (0.157 in.)
|
92
| 3.4 mm (0.134 in.)
| 96
| 4.2 mm (0.165 in.)
|
93
| 3.6 mm (0.142 in.)
| 97
| 4.4 mm (0.173 in.)

2. INSPECT FORWARD CLUTCH DISC |
Replace all discs if one of the following problems is present: 1) a disc, plate or flange is worn or burnt, 2) the lining of a disc is peeled off or discolored, or 3) grooves or printed numbers have even a little bit of damage.
- NOTICE:
- Before assembling new discs, soak them in ATF for at least 15 minutes.
3. INSPECT FORWARD CLUTCH PISTON |
Check that the check ball is free by shaking the piston.
Check that the valve does not have leaks by applying low-pressure compressed air.
4. INSPECT FORWARD CLUTCH DRUM |
Using a dial indicator, measure the inside diameter of the forward clutch drum bush.
- Maximum inside diameter:
- 24.08 mm (0.948 in.)
If the inside diameter is more than the maximum, replace the forward clutch drum.
