Pressing Out Bearing
allow propeller shaft yoke to be moved downward.
Support front of propeller shaft on stand so that
propeller shaft is horizontal (Fig. 4C-2).
2. Using piece of pipe or similar tool with diameter
sufficiently large (slightly larger than 1 1/8") to
encircle the bearing shell, apply force on yoke (Fig. 4C
3) until downward movement of yoke and stationary
position of journal forces the bearing assembly almost
out top of yoke (Force applied on yoke will shear
nylon retainers which hold bearings in place).
3. Rotate propeller shaft 1800 and repeat preceding step
to partially remove opposite bearing.
4. Complete removal of these bearings by tapping
around circumference of exposed portion of bearing
with small hammer (Fig. 4C-4).
5. Remove joumal from propeller shaft rear yoke.

will allow propeller shaft fmed yoke to be moved
,
downward (Fig. 4C-5). Support rear of propeller shaft
,
on a stand so that propeller shaft is horizontal. Be sure
weight is evenly distributed on each side of splined
yoke.
2. Using piece of pipe or similar tool with diameter
sufficiently large (slightly larger an 1 1/8") to
encircle the bearing shell, apply
?
orce on propeller
shaft fmed yoke until downward movement of propel-
ler shaft fmed yoke and stationary position of journal
forces the bearing assembly almost completely out top
of yoke (Force applied on fmed yoke will shear nylon
retainers which hold bearings in place).
3. Rotate propeller shaft 180" and repeat preceding
step to partially remove opposite bearing.
4. Complete removal of these bearings by tapping
around circumference of exposed portion of bearing
with small hammer (Fig. 4C-4).
5. Remove splined yoke and journal from propeller
shaft front fmed yoke.
6. Remove bearings and journal from splined yoke in
a similar manner.
CLEANING AND INSPECTION
Clean and inspect outer surface of propeller shaft
splined yoke to ensure that it is not burred, since burrs
will damage transmission seal. Also, inspect splines of
yoke for freedom from dirt.
ASSEMBLE UNIVERSAL JOINTS
NOTE:
If universal joints are disassembled new bearing
and journal assemblies must be used for reassembly.
Consult parts book for repair kit part number.
