DISASSEMBLY - CROSS AND BEARING KIT
1. The implement driveline has been removed
from the machine, the two halves
separated, and the guards removed. Start
the procedure by removing the yoke that
does not have a shaft attached.
2. The bearing cups are held in the center
housing by snap rings. The snap rings are
on either the inner edge of the bearing cup
(internal), or on the cup end (external).
For internal snap rings, put a shop cloth
under the snap ring to catch the snap ring.
Use a screwdriver and a hammer to drive
the snap ring off the bearing cup. Figure
MntP-R-0128
For external snap rings, the snap rings are
against the outer end of the bearing cup.
Use a hammer and a driver (that is slightly
smaller than the bore) to lightly hit the snap
ring. Figure MntP-R-0129 and MntP-R-
0130 This will drive the bearing cup away
from the snap ring and loosen the snap
ring. Remove the snap ring.
3. Set the end yoke on the vise so the ears
are supported by the jaws of the vise. Hit
the center housing to force the bearing cup
out of the center housing. Figure MntP-R-
0131 The bearing cup will only be forced
part way out of the center housing. Note:
When hitting the center housing NEVER hit
the machined surface of the center
housing. If the machined area is damaged,
the guard will not rotate freely. NEVER hit
the area around the hole for the bearing
cup. Distortion of the hole will make
removal of the bearing cup difficult.
4. Repeat the procedure to push the other
bearing cup part way out of the center
housing.
5. Fasten one of the bearing cups in the 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. Figure MntP-R-0132 Do not
remove the other bearing cup from the
center housing at this time.
