Can the cutless bearing on an E-27 be removed without disconnecting the propellor drive shaft??? Thanks chris
I have been asked on the Sailnet list to post the following pics of the puller I use for removing and installing a cutlass bearing without removing the shaft. This was made by a friend with an O'Day 34 with a shaft larger than my 1" shaft so I had to make up a new split pusher sized for my boat. I have only used it on my son's C+C 29 with a 7/8" shaft for which I wrapped a copper wire around the shaft to center the pusher.
Looking at the top picture: Block A goes behind the strut with a central hole big enough for the bearing to pass through easily.
Block B is split in halves with a central hole large enough for the shaft only. It goes in front of the strut and pusher.
The dark tube on the shaft represents the bearing in the strut.
The lighter gray tube is the pusher and is split in half down the long dimension. This piece is longer than the strut, slightly smaller than the outside diameter of the bearing and larger than the shaft. I used a pipe nipple that was about 1.31" od and turned it down to under 1.25". I put a hose clamp around it to hold the halves together. The pusher has to be large enough to push against the brass of the cutlass bearing. With a 1" shaft and a 1 1/4" strut the diameter the brass is not very thick.
When assembled, tightening the nuts on the 1/2" threaded rods pushes the cutlass bearing aft and out of the strut. It will also push the new bearing into the strut.
I noticed a groove in my shaft where the packing material has worn in over the years (noticed it when i pulled the transmission for rebuild); it's not a big problem but i suppose i have to replace packing material more often. I wondered if just shortening the shaft a little would put the packing material on an unworn section of the shaft. If you had such a groove; what would you be up against in shortening the shaft; in your case 1 1/2"?

Where does one get a split coupling? It sounds like a good idea!
