Post a picture of what your looking at.

A picture is worth a thousand words is what I have been always told. A couple pictures of the motor and motor information tag would help as there were several different motors used in Shopsmiths and they do not all come apart the same way. Some bearings are press fit and others are held in with retainer ring and screws. Be sure to mark the end plates and housing with a mark/knot so you know how to reassemble these parts.

I have a set of Jacob Anderson's DVDs (listed on Ebay), one on rebuilding the headstock and one on how to repair 4 different type motors. I review them quite often to make sure I do not forget any information/tips when working on headstocks. I believe they were one of my better Shopsmith investments for doing repair work.

Nevermind. Got it. The ol' rubber mallet. Now I'm working on the quill sleeve...

Ha! I pulled bearings! Now to replace them...

Couple questions:
- The inside of the motor is still dusted with sawdust. I blew out what I could; is it ok?
- When I put bearing back on, do they have to go in the exact same spot? How do I know what the exact spot is? Should I have marked them somehow?
- One of my snap washers is slightly bent. Will it work? Get a new one?
- Does anyone have a wiring diagram for a greenie? I pulled the wires without diagramming.

Thanks!

Again a picture would be helpful. Generally speaking white to white (neutral), black to black (hot), green to green (ground). No idea what your wire colors are. Bearings usually have some type of stop when they are fully seated. Could be a change in shaft size or maybe a snap ring. It's always a good idea to take pictures or make a drawing before, during, and after disassembly to aid in putting it back together. The Shopsmith website has exploded views of the headstock but not the motors. If you think you have weakened the snap ring, replace it, otherwise just straighten it out and re-use it.

Ed - Is it a 3/4 horse General Electric motor?

My MOD (Model?) is 5KC39NG 202. Does this match yours?

If so, I'll post my "drawing" tonight. Not to say I told you so, but I told you to make a drawing.

And as long as your this far, what shape is your power cord in? Now would be a good time to replace it.

Yes, I have the exact same one. Already replaced power cord. Pulled the wires before anyway said something. Hasty. Hasty.

So I'm suspecting that I'm up a creek with the locations for these new bearings...is that so?

Pics tonight... I hope.

Take the bearings to a bearing dealer or motor shop if any are close by. If you have any way to measure (within +-.002") the ID, OD and width, then finding bearings on-line is easy. The number on the bearing can cover several different IDs & ODs so they always need to be measured to make sure of the correct replacement.

If you are unable to measure or find these bearings, I have many different bearings for all the Shopsmith uses available. Let me know and mail the old bearings to me. I will only charge my cost and postage when returning new ones to you. I also stock almost any Shopsmith part if you find you cannot get the part from Shopsmith.

Thanks Bill. That's helpful, and I may be in contact if I can't find the right bearings at my local shop (Rocky Mountain Supply in Fort Collins, CO).

My main concern at the moment is finding the right spot on the shafts where the bearing used to be. I took bearings off the quill (single bearing type), both bearings off motor shaft, and both bearings off drive shaft (the thing connected to quill). I'm hoping there are marking on the shaft that indicate where the old bearings were, but I'm a little doubtful.

Oh, and I'm assuming the bearing puller becomes a bearing "pusher-back-on-the-shaft" tool.

Only if it can reach the other end of the shaft!
