check cut motor

[unitedcases]

If anyone could wear out a cut motor bearing, it would be you! How many hours on that motor?

I think it was an original motor. So I would say we'll over 1000. That's a guess though. My oldest machine, "old timer", is about 80 hours away from the illustrious 3000 hour mark. With 400 hours still lost in space from frying the computer at an earlier time before we knew that vacuums were bad...

I've put about 3 hours on my new motor and can't help but think it sounded quieter when I first installed it than it does now. Not a whine, but more of a vibration. Enough that the Y belt oscillates 1/4" inch or so each way. If I touch the motor casing while it is running there is a noticable increase in vibration at the commutator end. But I took the motor out and apart today and the bearings were tight, brushes were fine, the commutator measured concentric and everything was tight and otherwise seemed ok so we'll see what happens after a few more hours. And the CCM error is still there nearly every time.
