Some time ago there were several discussions and photos about the various quill shaft designs used with the earlier two-bearing poly v quills. Specifically, the two-piece shaft with the roll pin. I can't seem to find that info now. Anyone remember the threads or postings??
I have a '63 goldie that came with a two-bearing quill upgrade from the previous owner. It has always had what I think is excessive backlash at the saw blade tip. It measures @ .125 to .130 if I remember right. Shortly after I got the machine a couple of years ago, I replaced the drive sleeve which included a new drive ring. This seemed to help at first but in a short while, the same issue was still there.
My questions for our expert rebuilders and others are: If I disassemble the quill, and if I find it has a two-piece shaft with a loose roll pin, has anyone had success with replacing the roll pin with a tapered pin? Also, if I don't see an obvious cause, how does this amount of backlash compare to other machines (newer or older)? Any thoughts or experience info would be appreciated.
Thanks, John McCrossen
There is a lot of discussion in the thread that Ed (reible) found for us. There are also very good photos of the rollpin in post #38 of that thread - by jcbrowne.
The backlash in my machine has varied from time to time, I am guessing it is caused by the play in the plastic coupler (Drive and Ring Assembly PN 514083) or the (Drive Sleeve Assembly, PN 518145) . I have not figured out which part is which from the exploded diagram. My guess is it would be the most expensive!:confused: A phone call to SS would answer this, but I've not made one, as yet. As long as the Mark V is still working, I'll hold off on getting a replacement. (just to see if that's the cause)
Good luck! And thanks Ed, for your search and the link!:)
