Idler shaft sheave speed loop/bearing/button

[bnssweeney@msn.com]

New guy here. Got a 55 vintage greenie, (first SS) and am going thru it headstock first. I have the rebuild kit and everything is pretty straightforward except for the speed loop/bearing/button that goes in the end of the control sheave shaft, what is the process for removing and replacing that component. Looks like a tap it out and press the new part in. Guidance pls. Thx Steve

I have not had good success just replacing the bearing in the control sheave. Once removed, it appears the holding power of the control sheave tube is reduced. Loctite helps but I still had a few failures. I have been machining the bearing depth around .08" to .09" deeper so there is material to stake the bearing. Shopsmith did use a bunt chisel like tool at 4 places around the bearing for staking for the extra hold. This extension pass the end of the bearing for staking was present in some of the earlier control sheaves.

My Ebay friend has the control sheave bearing, button and retaining loop available on Ebay which I use. Excellant seller to do business with.

Thx Bill, I'll Pay attention w/loctite and crimp/stake over the end and keep an eye on it and hope for the best. Steve
