All good suggestions, thanks. The bearings seem fine and I can’t detect any bend in the shaft, although I don’t have a dial indicator to be sure. The strange this is that with just a little bit of support under the motor it runs smooth and quiet but when the motor hangs free it shakes. I’m thinking of removing the spring loaded mounting pins and just bolt the motor the mounting support to see if that clams thid thing down.
