fractures.

Cams on the center cam and driven clutch must

not be excessively chipped. A smooth wear pattern up

to 50 percent face width is acceptable on clutch cams.

Holdout rings have a frictional resistance to

rotation obtained by friction spring. Check for fractures

or severe chipping of cams on this part.

Friction spring wear should not exceed .003 inch

at points of contact. Compare with measurement at

unworn portion. If extreme care is not exercised in

removing this part, It may be damaged. Replace with

new part if, after assembly, the holdout ring rotates

easily. It should, how- ever, be possible to rotate it by

hand. Compare with a new port.

Center cam must be free to rotate within limits of

keys in spider.

Check the spring retainers for fractures or spline

damage.

Breathers

Wash breather on axle housing with solvent shake

dry. Make sure breather is not clogged.

The following instructions describe the procedure to be

followed when reassembling and installing components

of axle. Instructions cover reassembly of only one side

of axle. Reassembly of opposite group is identical

unless otherwise noted.
