Fig. 4E-1 1 Tapping Out Bearing
2. Using piece of pipe or similar tool with diameter
sufficiently large (slightly larger than 1 1/8") to en-
circle the bearing shell, apply force on propeller shaft
fixed yoke until downward movement of propeller
shaft fixed yoke and stationary position of journal
forces the bearing assembly almost completely out
top of yoke (Fig. 4E-10). This will shear nylon retain-
ers which hold bearings in place).
3. Rotate propeller shaft 180" and repeat preceeding
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. 4E-11).
5. Remove journals from propeller shaft fixed yoke.
6. Remove bearings and journal from splined yoke in a
similar manner.
