Propeller shaft with greater than .002 run out will soon be broken seal with oil
leaking out at high rpm levels.
Prop shaft run out should be checked before shaft is removed from unit.
Driveshaft bearing play from side to side can be measured at this time.
Pinion gears with broken shafts or pinion nuts are best removed by drilling one
13/64 inch hole to aid in removing dowl pin from the clutch dog.
If you can remove the spring, and push out the dowl pin the drive shaft will pull out
easy .
After hole is drilled a long 3/16 punch will move the 1/4 inch dowl pin to the
side and allow the drive shaft to come out.
Hole can be filled by tapping hole with a 1/4 - 20 NC. thread . Fill with stainless
steel set screw and then using 680 green loctite to hold unit in place.
