If you are referring to the pulley in the Control Sheave (110), I did not know that it could be replaced. Are you referring to the pulley that has the Retaining Loop (111) that hooks over the Quadrant (86)?

Refer to the Exploded Parts Views in the online PDF catalogfor the reference numbers in parenthesis in the paragraph above.

Contact me at annbill.mayo@comcast.net as I have replaced many of these bearings. I recommend replacing this bearing and it's associative parts (retaining loop and button) if needed. Any pictures of these parts and the speed control assembly and quadrant will help assist in determining what needs replacing.

I find small manufacturing differences between control sheave ID and idler shaft OD where many control sheaves (new & used) will not fit or be too loose on a used idler shaft. I only have matched set of control sheave and idler sheave and shaft available for this reason. Therefore just replacing the bearing insures the control sheave will still work with the idler shaft. I have unique tools made for this task therefore I do not recommend this task for most Shopsmith owners.
