Yes- this is similar to what was posted already. I have a Sears Craftsman 10 table saw. the model number is 315.228490 ser# p0237-01879. I am not sure if the arbor bearings are going or the motor. There is a very loud squeel/screatching noise that was not there 2 months ago. Since I am hearing impared, I cannot tell where the sound is coming from (was told by my daughter that it is making the noise). I do not understand the directions that were given on replacing the bearings. I also am not sure where to take it to have it done. If I need to replace the motor (wired it for 240/from 120 orginal) Searns no longer makes or supplies the motor. Where could I find a new one? Also since I am not all that mechanically inclinde (have a tendency to be impatient) I need suggestions as of to where I might be able to take it to have the work done. I live in Milwaukee, WI
Any help that could be given would be appreciated by me.

Look up electrical repair in the phone book or google it for your area.

Just a couple of weeks ago I over filled my old seco dust collector, 2 times in a row. Then I noticed a horrible noise. Wasn’t long that it just stopped working. Found a guy that solely works on electrical motors a town over from me. After he disassembled it he said that the bearings were not the correct bearings for the machine. He added some that have urethane in them. Said they will repel what ever dust might get in. If you do not find anyone in your area that works on motors, let me know. Maybe you can ship the motor to him. Anyway… This dust collector now works better than the day it was new.

If the saw is belt driven, remove the belts and turn the saw on. If the noise goes away its the arbor. If not, its the motor bearings. Bearings are very easy to replace and only cost a few dollars. If you take the motor to a shop look at about $200 for a $25 dollar job if you do it yourself. The arbor bears can also be replaced. Get a copy of the manual at owwm and have at it

What Ken said. A motor shop will do the work for you. You say you are not very mechanically inclined. Might be your best bet. If it is the saw bearings that are bad, you can do those yourself. Look at the Vintage machine site and they will have much information on your saw. Look for an exploded parts drawing. Take it slow and easy. Its surprising what one can do if needed. Good luck. bob

Another thing to check is whether a pulley is rubbing. I had an old (new when I bought it) Rockwell contractor’s saw which loved to have it’s arbor pulley creep over until it would start rubbing on the sheetmetal. Made a screeching sound. No matter how hard I tightened the allen screw, it would always do it again, eventually.

The squealing, screeching sound doesn’t sound like bearings to me. Ball bearings that are going bad make more of a rumbling sound. Sears bearing are especially problematic. Even new, they sometimes sound like they used pea gravel for the balls. (Sorry, don’t mean to insult your saw).

Just occurred to me: slipping belts can make a squealing sound too. But that’s more on startup than continuous.
