6. Note the orientation of all grease fittings
before removing any yokes or crosses.
Remove the end yoke from the center
housing.
7. Repeat steps 2 - 6 to remove the shaft yoke
and cross from the center housing.
8. Use the hammer and the driver to remove
the two bearing cups from the center
housing. Figure MntP-R-0133
9. Remove the snap rings from the end yoke
and the shaft yoke. (Refer to Step2)
10. Set the end yoke on the vise so the
trunnions of the cross are supported by the
jaws of the vise. Hit the end yoke to force
the bearing cup out of the end yoke. The
bearing cup will only be forced part way out
of the end yoke. Note: When hitting the end
yoke NEVER hit the area around the hole in
ear. Distortion of the hole will make removal
of the bearing cup difficult. Figure MntP-R-
0134
11. Repeat step 10 to push the other bearing
cup part way out of the end yoke.
12. Fasten one of the bearing cups in the vise.
Make sure the jaws of the vise are as close
to the end yoke as possible. Hit the end
yoke to drive the yoke up off the bearing
cup, similar to Step 5.
13. Repeat Step 12 to remove the other
bearing cup from the end yoke.
14. The opening between the ears on the end
yoke is wider on one side. Remove the
cross from the side that has the wider
opening.
15. Repeat Steps 10 - 14 to remove the cross
from the shaft yoke. Be careful not to hit the
grease fitting in the shaft yoke.
