[C320-list] Cutless bearing replacement

[sail-ability sail-ability]

make sure that there are no TWO grub screws holding the bearing in 
place! occasionally I've seen two in the same hole, the outer one being 
used as a lock, which is not necessary.
Good Luck

          NoWell the short answer to that Joe, is that I am too tight to 
spend $50 on collets and $50 on international shipping when I can build 
the whole thing for under $50 at home.  They're not rocket science! 
Also I am making it dual purpose so that I can use it as a prop puller 
as well!

  Having said that I am making a big assumption here - namely that the 
fact that the bearing has two retaining grub screws means that it isnt 
going to be THAT tight a fit in the bracket!

  We shall see

  Cheers

for the tool you wish to make.  Those are the only precision required 
pieces for the tool to work.  I bought the Strut-Pro tool about a year 
ago and used it last summer to replace my cutlass bearing last summer. 
Worked like a champ.  Tool cost was about $350 as I recall.  But, they 
will sell just the split collets for various shaft sizes.

bearing.
