Direct Clutch Preinspection
Direct Clutch PreinspectionClutch operation
1. Set the direct clutch drum onto the transaxle case.
Caution: Applying compressed air to the assembled clutch pack for longer than 3 s at a time will damage the seal. Do not apply compressed air for more than the aforementioned time when testing the system.
2. Inspect the clutch operation by applying compressed air as shown.
Air pressure:
392-441 kPa (4.0-4.5 kgf-cm2, 57-63 psi)
3. If not as specified, replace parts as necessary.
Clutch clearance
Measure the direct clutch clearance.
1. Install the direct clutch in the transaxle case, and set the dial gauge.
2. Secure the direct clutch by lightly pressing down with a press or similar tool.
3. Apply compressed air to the part indicated in the figure and let the direct clutch piston stroke three times.
Air pressure:
392-441 kPa (4.0-4.5 kgf-cm2, 57-63 psi)
4. Apply compressed air and operate the direct clutch piston. Read the value when the indicator of the dial gauge stops.
5. Release the compressed air and read the dial gauge when the direct clutch piston is not operating.
6. Calculate the direct clutch clearance according to the following formula: step (4) value - step (5) value = direct clutch clearance.
7. Measure the clearances at four locations (90° apart) by following the steps from (3) to (6). Verify that the average value is within the specification below.
Direct clutch clearance
Standard: 1.10-1.40 mm (0.043-0.055 in)
8. If not as specified, replace parts as necessary.
