Shaft and coupling, separating

[Don]

1982 Hunter 27.Do I need a puller to get the coupling off of the shaft? I am replacing the shaft, sould I just cut the old one? I read the shaft and the coupling are a press fit. If this is true, how do you put it back together in the boat?

Shaft Coupling

I removed the coupling flange on the shaft in my 37C so I could install a new PSS Dripless shaft seal. It was very difficult. The process involves removing the existing bolts, separate the two mating flanges and inserting a spacer (such as a socket), then using longer bolts pull the two mating flanges together. The spacer will push the shaft out of the flange. The two day process involved many iterations of tightening the bolts and hitting the flange with a hammer using very short strokes (due to space limitations). Also, due to space limitations, I had to use two or three sets of different sizes of bolts. At first progress is extremely slow, but gets better with time. Putting the flange back on the shaft was much easier. After lubricating both, just pushed it on by hand.

Bob Is Right On, One Caution

When you are pulling the flange with the bolts be extra careful that you don't drive the longer bolts through the back of the transmission. As you tighten them and the flange is sliding off the shaft, you are putting the bolts further and further through the transmission flange. They will eventually hit the back of the transmission. Hence Bob's comment that he had to have three different lengths of bolts.

It would be a lot easier to take up golfing.

Don, send me an email message...

If you'd like I can give my phone# and explain...it really is not a difficult job...the absolute hardest part about the whole thing is the damn cutlass bearing replacement...
