Universal Joints and Drive Shafts
1. Remove the two snap rings.
2. Get a block of soft metal with a hole large enough for the bearing to pass through.
3. Place the round bearing over the hole and hammer on the opposite bearing with a soft metal punch until the body of
the spider hits the inside forks of the yokes. It may be necessary to tap the outside fork of the yoke with a hammer
until the bearing pops out.
4. Repeat the procedure for the other bearing, then remove the spider.
5. Insert the spider into the bearing holes in the forks of the yokes.
6. Insert the bearings into the holes in the forks.
7. Put the assembly in a vise and press the bearings together until the bearings are flush with the forks.
8. Assemble the snap rings in the snap ring grooves. The bearings may have to be tapped inward enough so the snap
ring groove is in a position to receive the snap rings. After the snap rings are in place, tap the outside of the yoke near
the bearings to draw the snap rings against the machined inner surface of the yoke arms.
9. The first operation is to attach the fitting yokes to the two shafts to be connected. Care should be used when doing
this, so as not to nick or bend the flanges to which the bearings are fastened. Then the yoke retaining nut is tightened
to prevent it coming off the shaft.
10. The next operation is to bring one end of the universal joint and shaft up against one of the fitting yokes. It will be
noted that one of the bearings is inserted in the keyway in the yoke with the male arced surface pilot of the bearing,
resting on the female pilot of the yoke. Due to the fact that there are cork packings between each of the bearings and
the trunnions on which they fit, this cork packing must be compressed a certain amount, before it is possible to enter
the male arced surface of the other bearing with the yoke pilot on the opposite side.
11. This should be done by clamping the two opposite bearings with a "C" clamp. Then push the bearings into the yoke
pilot and keyway. Do not attempt to put the bolts through into the bearing until both of the bearings have found their
seat on the yoke surface. The bolts are then inserted through the yoke and screwed into the bearing. It will be noted
