I replaced the bearings and put the motor back together. Got it back on the machine and was able to zero the machine. The bad news is within seconds of running the machine/program, the noise started again. And in about a minute it overloaded. This was the first the first motor I have ever taken apart, and Im now guessing that the noise/problem is coming from 3 of the 4 magnet strips not being attatched to the outer body/tube. I wondered if that was ok when it was apart, and Im now guessing its not ok. Do you think that could be the problem? Is it possible to re attatch those magnet strips to the body/tube? Thanks for your time on this.
