Assembly (Cont’d)
9. Using the large driver used in disassembly, drive
one of the bearing cups into the yoke until the
groove for the snap ring can be seen. Make sure
the ear of the yoke is flat against the bench. If
the grease fitting in the yoke is down, support
the yoke on a block to prevent damage to the
grease fitting.
10.Make sure the groove for the snap ring is clean.
Install the snap ring. Use a screwdriver to push
the snap ring into the groove all the way around.
11. Set the shaft yoke on the vise so the shoulders
of the cross are supported by the jaws of the
vise.
DO NOT allow the machined surfaces to
contact the vise. Hit the yoke with the hammer to
seat the bearing cup against the snap ring.
DO
NOT hit the yoke near the opening for the
bearing cup. (MntP-R-0171)
12.Repeat Steps 9-11 for the other snap ring.
13.Repeat steps 1-12 for the end yoke.
14.Wrap a shop cloth around the shaft to protect
the splines. Clamp the shaft in the vise so that
shaft yoke is up. The ball in the shaft yoke has a
flat area around each end of the hole. The flat
area is wider on one side of the ball.(MnR-0454)
15.Rotate the center housing so the grease fitting is
away from the shaft yoke. This will align the
grease fitting in the center housing with the hole
in the guards. The grease fittings in the center
housing and the cross must be toward the same
side of the assembly. Make sure the pin of the
center plate in the center housing is clean. Install
the pin in the ball and cross in the ears of the
center housing. (MntP-R-0172)
16.Make sure there is grease in the holes for the
bearing cups in the center housing. Push the
cross to one side of the yoke.
17.Use the cross trunnion as a pilot. Start the new
bearing cup on the cross and into the opening in
the center housing. Push the cross into the
bearing cup while driving the trunnions of the
cross parallel with the openings for the bearing
cups. Hit the bearing cup lightly with a hammer.
Using the vise, drive the bearing cup in to the
yoke until the bearing cup is flush with the yoke
ear. (MntP-R-0173)
