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
MAN1258 (3/26/2018)
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. 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.
SERVICING TIRES SAFELY
Used Aircraft Tires (Figure 23)
WARNING
Do not attempt to mount a tire unless you have the proper equipment and expe-
rience to perform the job.
Always maintain the correct tire pressure. Do not inflate tires above the recom-
mended pressure. Never weld or heat a wheel and tire assembly. The heat can
cause an increase in air pressure and result in a tire explosion. Welding can
structurally weaken or deform the wheel.
When inflating tires, use a clip-on chuck and an extension hose long enough to
allow you to stand to the side — not in front of or over the tire assembly. Use a
safety cage if available.
Check wheels for low pressure, cuts, bubbles, damaged rims, or missing lug
bolts and nuts.
Never remove split rim assembly hardware (A) with the tire inflated.
