Rebuilding Friction Pack

Disassembly

1.Position clutch and universal joint assembly on a bench so that end is accessible.

2.Remove the long bolts on the outside of the housing that hold the friction pack together.

3.Remove the plate(s) and all internal components. Leave the yoke/hub intact.

4.Discard friction discs.

5.If rebuilding the overrunning clutch, refer to Rebuilding Overrunning Clutch, page 33, beginning with Step 2.

Inspection

1.Inspect the steel and iron parts for wear, warping, or cracks, and replace if necessary.

2.Inspect the yoke/hub for looseness. If there is more than.03 end play, replace.

3.Clean any rust or dust from the plate surfaces with a wire brush or steel wool.

Assembly

1.Place one new friction disc, then separator plate, then second friction disc into housing.

2.Add the pressure plate so that the flat surface rests on the friction disc. NOTE: The tangs on the plate must fall into the reliefs in the housing.

3.Add the disc spring so that its inside diameter contacts the fins of the pressure plate.

4.Assemble the compression plate and all the long bolts. Make sure all nuts rest in their pockets.

5.Tighten all long bolts to 30 lbs-ft.

Rebuilding Overrunning Clutch

Disassembly

2.Inspect the yoke/hub for looseness. If there is more than .03 end play, replace.

3.Using screwdriver, scrape any hardened grease from the overrunning key pockets.

Assembly

1.Using a multi-purpose high-temperature EP grease or equivalent lithium grease, inject one grease gun pump into each key pocket. Evenly wipe two more pumps over the overrunning surface.
