I've been doing a little machine maintenance this week. The jointer seem to run a little clunky, so I though I would replace the 14 yr old belt with a link belt. As it turns out the motor had shifted and the pulleys were bad out of co-planer. I adjusted the motor and went ahead and switched belts. It works fine, but sounds like a jet engine. I have a couple link belts on my compressor and band saw (both slower motors). I recall a little belt noise from the compressor when I switched, but nothing like this and it is long since gone. I know the link belts are directional and it is on the correct way. I think I might switch back to the original unless this is normal and it will settle down in a week or so. Thanks for any thoughts.
