into yoke from outside and press in with hand pres-
sure as far as possible. Insert journal cross into
bearing cup with grease fitting away from shaft. Be
careful not to disturb needle bearings. Insert

nal 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 ham-
mer. See Figure 27. 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 with-
out restriction.
