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. (MntP-R-0167)
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. (MntP-R-0168)
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. (MntP-R-0109)
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 ear.
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
.
8. Put the shaft yoke into the vise so the bearing
cups are square with the jaws of the vise. Make
sure the trunnion is aligned with the bearing
cups. Tighten the vise until both bearing cups
are flush with the yoke. (MntP-R-0170)
