Reverse Clutch Clearance

Reverse clutch clearance
1. Measure the reverse clutch clearance.
1) Install the reverse clutch into the end cover, and set the dial gauge.





2) Secure the reverse clutch by lightly pressing down with a press, etc.





3) Apply compressed air to the part indicated in the figure and let the reverse 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 reverse 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 reverse clutch piston is not operating.
6) Calculate the reverse clutch clearance according to the following formula: Step (4) value - Step (5) value Reverse 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.

Reverse clutch clearance:
1.00-1.30 mm (0.039-0.051 in)

2. If not as specified, replace parts as necessary.
