Hey folks. Last week, I picked up a Craftsman 152.221240 from CL. Going in, I knew the saw had a problem bogging down when cutting through pretty much any type of wood – the previous owner explained that up front, and reflected it in the price. He just didn’t want to invest the time in figuring out what the problem was & fixing it.

This is my first table saw, so in my head, I’m thinking: worst case, I have to buy a new motor. Sounded manageable.

So got it home, examined everything, and found that the arbor pulley needed to be replaced. The inside of the pulley was worn to the point of being slightly oblong, and the key that goes with the pulley was missing. I’m assuming the saw ran without the key for a while—that may explain why it was bogging down, and also why the inside of the pulley was so worn out.

So I order a new pulley and new key from SearsPartsDirect. New pulley arrives, but the key was backordered and eventually discontinued according to Sears. No prob, picked up a new key from the local hardware store.

Went to install it earlier tonight – the key fit perfectly in the new pulley, but wouldn’t fit in the arbor shaft. Upon closer examination, it looks like the threads on the pulley-side of the arbor shaft were worn down by the spinning pulley, which in turn narrowed the opening for the key. See the attached pic.

I was able to file the opening a little (as well as the bottom of the key) to get the key to fit. However, there aren’t enough usable threads at the end of the shaft to screw the nut on more than a couple turns. So the pulley is sitting near the end of the shaft, with room for lateral movement—probably not usable that way.

Unfortunately, the arbor shaft (part # OR91022) is no longer available on Sears website. Not real sure where to go from here… any thoughts/advice would be greatly appreciated.

Thanks
Jason

I would be inclined to remove the complete arbor bracket. This can be done easily with the top removed, it requires the removal of a cross pin that holds and hinges the bracket. Take the assembly to a machine shop and see if they can cut new threads or otherwise secure your pulley.

Thanks for the response. Before I take it to a machine shop, I’m going to see if a collar with set screws will work for securing the pulley, in place of the nut. Or possibly a two-piece clamp (since that will probably be easier to attach given the slightly larger OD at the end of the shaft). Guess I’ll just order a couple different types and see which one works best.

Also, check the length of that arbor and see if it is standard LENGTH. Some Craftsman arbors are short and I got rid of a saw because I couldn’t use my Dado set on it. If you are going to have something fabricated make sure it’s standard length as well. Just a tip.

The 22124 was made by Steel City/Orion and was nearly the same saw as the Steel City 35601/35605/35606/35610 IIRC. The Cman 22104 and 22114 had pretty similar innerds too. SC is now out of business, but you may be able to source parts from whoever has taken over their parts supply.

In a pinch, successor models were the CMan 22116 (current model), Ridgid R4512, and SC 35925/35930…they had some similarities, but the trunnion systems were different, but you just might find that the part fits if you’re running out of options…worth a look into some of their parts diagrams.

The Cman 22124 arbor are the same length as most saws in this class of saw. My 22124 accepted a full stack, but you need to leave off the washer…a pretty common occurrence.

No die is gonna clean up those threads. That shaft is a goner.

Have you tried E-Bay?

Think I’d look for a donor saw.

knotscott – thanks. I’ll find the Steel City part # to see if I can find a replacement that way.

01ntrain – yes, I’ve checked eBay, but only using the part # in the Craftsman manual. I’ll look using the other part #s now, as well.

Good news – following knotscott’s suggestion, I found a replacement arbor shaft from a company called Nordis that provides SCT replacement parts. Their number is 877-724-8665 in case anyone else needs it. Should be here in a couple weeks.

Before discovering that part was available, I secured the pulley on the existing shaft with a two-piece collar, and put the belt back on. When I turn the arbor manually, the belt comes off the top pulley by two “notches”. I’m pretty sure the top pulley is in the correct position (i.e., the same position it will be in when the new shaft arrives), which leads me to believe the bottom pulley is out of alignment.

See attached pics for: the top pulley with the collar holding it on, the belt coming off the top pulley after turning the arbor with my hand a couple times, and a picture of the where the bottom pulley is positioned on the shaft coming out of the motor.

To me, it looks like the bottom pulley should be positioned closer to the motor (instead of flush with the end of the shaft, like it is now). That would bring it in alignment with the top pulley. Tried to adjust it, but that bottom pulley is stuck on there and won’t move. The set screw is out, and I don’t think there’s another one below it. Any tips on how to get that thing off? (without taking the entire motor out :) )

I wound up removing the motor this weekend to get access to the pulley. It was stuck on there pretty good – actually had to rent a puller from the local auto parts store to get it off. Everything is back together now, with the motor pulley positioned closer to the motor to align with the eventual position of the arbor pulley. Now I just have to wait for the new part.

Thinking ahead – to replace the arbor shaft, should I plan on removing the bracket first, or can it be done in-place? Any special tools needed?

The new arbor shaft arrived a little over a week ago. To install it, I removed the bracket, and tried removing the old shaft / bearings with a dead-blow hammer (copying something I saw on youtube). That didn’t go as smoothly as it did in the video, so I rented another puller from the auto parts store and that made things much easier.

Long story short, the new arbor shaft is installed & the saw is back in working order. Thanks everyone for your help.
