Loren - You don't have to remove the headstock from the tubes. Use a 4x4 block and a 2x4 in back of the headstock to keep it elevated at a angle so you can see inside. When you drop the motor pan, place a 2x4 underneath it to support the pan while you undo the motor pan screws. The bench tubes will support it and you don't need the special built plywood mount to place the headstock on.

Go for it............

I am able to remove the idler shaft, but only into the machine. If I try to pull it out, it hits the idler sheave. I cannot get that sheave off. It seems that there is a retaining ring (like a washer with a slot in it for the shaft key) holding the sheave on, and I cannot get it to move. (see picture "idler sheave") Any ideas? I was able to remove the small clip that sits just above that retaining ring. I would like to get everything apart for cleaning.

See picture "control sheave" for the reason I was hearing noise. I don't think that's normal The speed control quadrant is in similar shape. (Picture "pork chop")

For my question about the idler shaft bearing not turning, see the picture "idler shaft bearing". The arrow is pointing to what I thought was the part that should turn with the shaft. However, the shaft seems to turn freely inside the bearing, so I'm guessing I am wrong.

I apologize for NOT informing you it 'ONLY' can be removed toward the inside!!!!!

The small bearing that butts up against the pork chop IS 'shot'. It should be button shaped and the 'button' stays stationary while the sheave rotates. Also a retaining ring which attaches to the 'button' is missing/destroyed/laying in the bottom of the motor pan. New control sheave needed(515556) and probably a new quadrant gear(504221). You might able to get along with only the control sheave, but the rough surface on the quadrant gear may/will cause the 'button/bearing' to fail again. The 'frozen' 'button' bearing is what damaged the quadrant(pork chop).

Getting the 'clip' out is good (AND necessary) to get the rear half of the pulley off the shaft. It is probably crudded up and will be stubborn to remove. It has a keyway (like the control half of the pulley) and the pulley half retains the key. Steady EVEN pressure towards the end of the shaft normally pointing towards the speed control IS needed(Sometimes QUITE stubborn!!!!!!). Because it can be stubborn(due 'probably' to insufficient lubrication and heating of what little oil is left) it really needs to come off so as to get some good oil present and crud removed.

Not sure of your 'shaft rotating in the bearing'. I will take another look at that after posting this. I will add any relevant comment to this then.

P.S. Since the idler shaft is a 'water pump' bearing, it has seals which go all the way to the shaft which prevents you from seeing the center ring which you normally see rotating with the shaft.

ALSO I looked again at the quadrant damage. Forget I said you 'might be able to use it'. It is damaged more than I initially realized. Get a new one also! Replacing it CAN be tricky(roll pin removal and replacement) so if you are 'timid', get the whole thing(504198). Since you also mentioned wobbling of the dial, the dial shaft may also be damaged anyway. Make sure the dial gear teeth(on the dial) are intact.

This is what it should look like.

Thanks for all of the replies. I intend to replace the control sheave and the quadrant, and possibly the entire speed control assy. Now I need to tear down the rest of the headstock to see what else I may need.

I saw on the online Shopsmith parts catalog that a number of parts are on sale. Is this really a limited time sale, or do they always offer those "sale" prices?

They do come and go.

BTW The last 'stubborn' control sheave pulley I removed finally came out after application of kerosene as a penetrating agent.

P.S. How far from Madison?

Well I better get moving so I don't miss the discounts. I'm going to try to get the rest of it torn down tonight.

I'm about an hour SE of Madison.

Don't rush this. It is a learning experience and ground that you will cross again. Pictures of the process, for your archive, are strongly recommended. I can't begin to tell you how many times I wish I had photos that I did not take.
