Inspection
1. Discard the two crosses, all of the bearing cups,
and all of the snap rings.
2. Clean the bores in the center housing and the
yokes. Inspect the bores for damage. Replace
any parts that are damaged.
3. Clean the snap ring grooves in the bores that
have them. Inspect the snap ring grooves for
damage. Replace any parts that are damaged.
4. Clean the trunnions of the center plate in the
center housing. Make sure that none of the
needles from the bearings have fallen into the
center plate area of the center housing. Make
sure center plate moves freely by hand.
5. Make sure the grease fitting in the center
housing is clean,
undamaged. Replace this if necessary. (MntP-R-
0164)
6. Inspect the ball in the end yoke and the ball in
the shaft yoke for scoring and damage. Check
the end play of the balls. The end play must not
be more than 0.025" (0.635mm). If the ball is
worn, replace the yoke. (MntP-R-0165)
7. Use you finger to check for grease in the ball in
the end yoke and the ball in the shaft yoke. If
there is no grease in the ball, the ball has not
been receiving grease. Also check the ball color.
If it is blue, the ball has not been receiving
grease. Check the grease fitting and the grease
passages in the shaft yoke. (MntP-R-0166). If
they cannot be cleared, replace the yoke and
shaft.
8. Fasten one of the bearing cups in a vise. Make
sure the jaws of the vise are as close to the
center housing as possible. Hit the center
housing to drive the center housing up off the
bearing cup. Be careful not to hit the machined
surface of the center housing. (MntP-R-0161).
