I see where it has worn into the sheave around the shaft bore.

A better(more pixels) picture of the motor/shaft may reveal it against the inner bearing race.

It is Item: 504205 (Reference #124) in drawing installed on the motor shaft

504205 Spacer Sheave ... $4.95

See https://www.shopsmith.com/ss_forum/view ... 59#p250959 for more info.

I would not simply replace the spacer(although if it is one of the thinner ones that were used a while back, that alone justifies replacing it).

The fan sheave has been damaged and a new spacer will merely slide into the groove worn into it and the rubbing will resume(eventually).

When restoring my Mark VII, I had similar wear to the sheave. There ain't no replacement sheave from SS so I took another path. You could do the same thing.

I will add a link when I locate the thread.

I was wondering if that was the spacer. I imagine that was part of what made it so difficult to remove. I am ordering the part tomorrow and looking forward to putting it back together and using it for the first time. Thanks again for your help!

I think I replied too soon. JPG, I didn't see your post until I searched for it. I'll have to adjust my forum settings.

If I understand correctly, the fan sheave as well as the spacer has been damaged. Here are a couple more pictures. I was hoping to get a new spacer-and now maybe fan sheave, and be done. It sounds like a may have to do a work around.

IIWM, I would do the retaining ring 'work around' and not worry about the sheave until something else happens to it.

It would also eliminate the wait for the mother ship to come in.

Thanks JPG, now I have to ask (maybe another) stupid question. If I were to follow your good advice, what kind of retaining ring and where exactly would it go? The retaining ring at the end of the shaft has a specific groove machined into the shaft.

There are NO stupid questions!

Any that will interference fit on a 5/8" shaft.

They are 'expanded' with snap ring pliers and slipped onto the shaft.

No, not the question that is stupid, it is the one who did NOT ask it that is stupid
