REVERSE INPUT CLUTCH PLATE TRAVEL CHECK
INSPECTION PROCEDURE





1. Apply an evenly distributed load to the clutch pack.
2. Apply medium pressure, approximately 27 Nm (20 ft. lbs.), on the selective backing plate.
3. Use feeler gages to check the reverse input clutch plate travel.
4. Check the travel between the selective backing plate and the reverse input clutch retainer ring.

The reverse input clutch plate travel should be 1.02 - 1.94 mm (0.040 - 0.076 inch).

5. Select the proper selective backing plate to obtain the correct travel. Refer to
Reverse input clutch backing plate selection.

REVERSE INPUT AND INPUT CLUTCHES INSTALLATION
