2. Set the yoke in the arbor press with a piece of tube
stock beneath it.
Place a solid plug on the upper bearing assembly
and press it through to release the lower bearing
assembly.

3. If the bearing assembly will not pull out by hand
after pressing, tap the base of the lug near the
bearing assembly to dislodge it.
4. To remove the opposite bearing, turn the yoke over
and straighten the spider in the open hole. Then
carefully press on the end of the spider so the
remaining bearing moves straight out of the bearing
spider hole. If the spider or bearing are cocked, the
bearing will score the walls of the spider hole and
ruin the yoke.
5. Repeat this procedure on the remaining bearing to
remove the spider from the yoke.
6. Make sure of proper position for reinstallation by
applying setting marks, then remove spider .
Inspection and Repair
Make necessary correction or parts replacement if wear,
damage, corrosion or any other abnormal condition is
found through inspection.
NOTE: When any part of the journal assembly (spider,
needle roller bearing) requires replacement, be sure to
replace the entire assembly.
Check the following parts for wear, damage, noise or
any other abnormal conditions.
1. Spider
2. Needle roller bearing
3. Yoke
4. Flange
5. Boot
Spider pin for wear
Spider pin should be smooth and free from fretting or
galling. Visible signs of needle presence is normal, but
wear should not be felt.

Propeller shaft run–out
Support the propeller shaft on V-blocks (2) and check
for run-out by holding the probe of a dial indicator (1) in
contact with the shaft.
Static run-out limit:
0.13 mm (0.005in)
TIR on the neck of the slip tube shaft (with a
boot).
0.25 mm (0.010in)
TIR on the ends of the tubing 3 inch from the
welds.
0.38 mm (0.015in)
TIR at the linear center of the tube.
0.38 mm (0.015in)
TIR for the full length of tube with 30" or less of
tubing.

Spline
The nylon-coated spline should be free from nicks and
dings and the underlying steel spline should not be
visible.
After cleaning the nylon coating spline, the coating
should exhibit only slight indicator of wear.
Grease volume is approximately 10 grams of grease in
total. Grease should be evenly applied to both the
female and the male slip splines using a small brush.
After assembly of the slip joint, the sliding joint should
be fully worked from the full collapsed to the full
extended position.
Play in the universal joint
Limit:Less than 0.15 mm (0.006in)
401RW023
Preload of the universal joint
Preload should be 0 to 49 N(0 to11.0 lb). Joints should
rotate smoothly and freely and should exhibit no rough
or ratchety movement.

Universal Joint Reassembly
1. Install spider to flange yoke. Be sure to install the
spider by aligning the setting marks made during
disassembly.
2. Pack the four grease cavities of the spider with a
high quality, extreme pressure N.L.G.I. Grade 2
grease. Do not add additional grease to the bearing
cup assembly.
3. Move one end of the spider to cause a trunnion to
project through the spider hole beyond the outer
machined face of the yoke lug. Place a bearing
over the trunnion diameter and align it to the spider
hole. Using an arbor press, hold the trunnion in
alignment with the spider hole and place a solid plug
on the upper bearing. Press the bearing into the
spider hole enough to install a snap ring.

4. Install a snap ring.
Be sure the snap rings are properly seated in the
grooves.
5. Repeat steps 3 and 4 to install the opposite bearing.
If the joint is stiff, strike the yoke ears with a soft
hammer to seat needle bearings.

1. Apply grease evenly to both the female and male
splines.
2. Apply a small amount of grease by finger to the
outer lips of the boot.
3. Slide the boot onto the yoke shaft being careful not
to damage the spline coating or boot.
4. Insert the yoke shaft spline into the sleeve being
careful to maintain proper phasing. The spider
holes should be in line and as per originally marked
prior to disassembly.
5. Position boot onto sleeve and yoke shaft in final
position over boot grooves.
6. Attach boot clamps and secure using pliers.
7. Be sure clamp is properly seated and secure.
