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 22. Install snap ring and
repeat on opposite cup.
4. Repeat Step 1 & 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.
