MAINTENANCE
ASSEMBLY
1. Apply grease to the bearing cup bores in
the end yoke, the shaft yoke, and the center
housing. The grease will make the bearing
cups much easier to install.
2. Install the grease fittings in the crosses.
Align the grease fitting with the correct
trunnions. Look at the old crosses. Figure
MntP-R-0138
3. Remove the bearing cups from the new
crosses and apply grease to the needle
rollers in the bearing cups. The grease is
used to hold the needle rollers in the
bearing cups during installation. Use your
finger to push the grease into the needle
rollers and to push the needles out against
the bearing cup. Figure MntP-R-0139
4. Wrap the shaft in a shop cloth to protect the
splines, and mount it in the vise with the
yoke up. Make sure the trunnions of the
new cross are clean. Install the correct
trunnions of the cross through the side of
the shaft yoke that has the widest opening.
The grease fitting in the cross must be
away from the ball in the shaft yoke. Figure
MntP-R-0140
5. Push the cross to one side of the yoke. Use
the trunnion as a pilot and push the new
bearing cup onto the cross and into the
opening in the rear.
6. Push the cross into the bearing cup to keep
the needles in the bearing cup while driving
the bearing cup. Keep 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 into the yoke until the bearing
cup is flush with the yoke.
7. Make sure the bearing cup is flat against
the bench. Keep the cross in the bearing
cup and start the other bearing cup into the
yoke. Use a hammer to lightly drive the
bearing cup into the yoke just far enough to
make sure the bearing cup is straight. If the
grease fitting in the yoke is down, support
the yoke on a block to prevent damage to
the grease fitting.
