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.
