1. Place seals securely on bearing cups. Insert cup into yoke
from outside and press in with hand pressure as far as
possible. Insert journal cross into bearing cup with grease
fitting away from shaft. Be careful not to disturb needle
bearings. Insert another bearing cup directly across from
first cup and press in as far as possible with hand pressure.
2. Trap cups in vise and apply pressure. Be sure journal cross
is started into bearings and continue pressure with vise,
squeezing in as far as possible. Tapping the yoke will help.
3. Seat cups by placing a drift or socket (slightly smaller than
the cup) on cup and rap with a hammer. See Figure 23.
Install snap ring and repeat on opposite cup
4. Repeat Step 1 and Step 2 to install remaining cups in
remaining yoke.
5. Move both yokes in all directions to check for free
movement. If movement is restricted, rap on yokes sharply
with a hammer to relieve any tension. Repeat until both
yokes move in all directions without restriction.
