Clutch.
REMOVAL (Illus. 4-43).
1. Remove transmission from engine.
2. Remove clutch from engine clutch removal is obvious. Therefore no removal procedures are given.
INSTALLATION (Illus. 4-43 and 4-44).
1. Check flywheel from correct depth. Flywheel depth should be 1.065 in. + .005 in.
2. Replace release bearing and carrier, and flywheel pilot bearing. Pilot bearing should be a hand press fit in the
flywheel recess and on the transmission drive gear. The release yoke or fork should contact the release bearing
carrier pads evenly to prevent a bind on the front bearing cap extension.
3. Friction face of the flywheel must be free from heat cracks score marks and taper.
4. Before installing the clutch, the intermediate plate should be set into the driving slots of the flywheel and clearances
checked. A minimum of .006 in. is recommended to allow for free movement of the intermediate plate.
5. The two disc assemblies for a two plate clutch may or may not be identical or interchangeable. In most cases they
will not be interchangeable and will be marked either flywheel side or pressure plate side. They must be positioned with
the side of the disc as marked, next or adjacent to the respective part. In no instance shall the hubs be allowed to
approach pilot bearing or come together within 5/32 in.
6. When installing the clutch, it is essential that a splined shaft or aligning shaft be used with a key to properly align the
two disc assemblies.
7. To obtain complete disengagement, the release levers must be actuated a specified distance from the engaged
position. Assuming the release bearing clearance (distance between the clutch release levers and release bearing) is
1/8 in. when the clutch is in the engaged position, the release bearing must move forward 1/8 in. to take up this
clearance before it contacts the release levers and then move the normal amount of travel required to disengage the
clutch as shown below.
NOTE
IF RELEASE LEVERS ARE NOT IN PLANE, IT IS AN INDICATION THAT COVER IS NOT
PROPERLY SEATED IN FLYWHEEL.
8. Check the distance from the top of the clutch flywheel ring (cover) to ends of release levers. Distance should be 1
3/32 in. 1/32. Satisfactory operation of the clutch depends upon the accuracy of the lever setting as this controls
parallel movement of the pressure plate.
9. Check release lever travel. Travel should be:
Release Bearing Clearance 1/8 in.
Normal Release Bearing Travel 1/2 in.
Total Bearing Travel Required 5/8 in.
