Hi:
I've removed the shaft and sleeve from the 0-21 engine a
few times.It's not to hard to do.
I don't know if you have the parts-catalog- if you do, it
would be easy to follow what I write.
a.) Open the little door at the engine block and loosen the
2 bolts which hold the shaft (watch for the key when you
remove the shaft)
b.) loosen the nut just back of the reversing gear housing
(watch for the clambing ring element that holds the sleeve)
c.) turning the operaing lever, and pulling the shaft back,
you can remove both shaft and sleeve. (If you want to
remove the sleeve from the prop, the sleeve has a LEFT
threat!)
d.) replace the 3 0-rings from the reversing gear and
another 0-ring inside the prop (unscrew the sleeve)
e.) replace the bush and the 2 seal rings from the stuffing
box
f.) replace the stern bearing (cut a V into the old bush
with a hack saw blade, that makes it easy to remove the old
bushing)
Second time around you'll be doing it blindfolded...
Wilhelm., V-257
