pair of bearings at each end of the shaft that are to assemble to the end yokes, are held in place by means of a
weld wire.
12. The weld wire has no effect on the universal joint action and need not be removed. Rather it should remain in
place to hold the bearings on the spider trunnions should the universal Joint have to be disassembled. Then
tighten the four bolts securely. After one end of the shaft has been put in place, the shaft can be compressed in
the slip joint to permit raising the other end of the shaft and then, coming forward against the yoke member
proceed exactly the same as stated above.
13. Should it be necessary to disassemble the joint for instance to replace a spider or bearing-it is only necessary to
remove the eight bolts (4 per each yoke), compress the shaft assembly in the slip joint and remove the spider and
the four bearing assemblies.
14. It may be that some of the bearings are tight in their respective pilots and key seats, which will make it necessary
to tap the top of the bearing slightly, in order to release it. Then, the spider and bearing assembly can be replaced
in part or as a complete unit.
15. When installing a double universal joint assembly, it is important that both of the universal joints operate at equal
angles. It is also important that the slip yoke and the yoke welded to the tube are in the same plane.
