Insert another bearing cup directly across from first

Trap cups in vise and apply pressure. Be sure jour-
nal cross is started into bearings and continue pres-
sure with vise, squeezing in as far as possible. Tap

smaller than the cup) on cup and rapping with a
hammer. See Figure 20. Install snap ring and repeat

3. Repeat steps one and two to install remaining cups
in remaining yoke.
Move both yokes in all directions to check for free
movement. Should movement be restricted, rap on
