>Ruth Pull the belt off and run the motor by itself. This stick a piece of wood against the pulley to put some tension on it and see if it's making the ticking noise. I've had a motor go bad when a screw came loose inside the motor. it started making a ticking noise. Wasn't a Power tool motor it was a dust collector.
I also had a bearing make a ticking noise once in another lathe. The bearings weren't aligned parallel to each other. A machinist friend clued me in on that one. He measured them and then pressed one of them on one side a little and the ticking went away. I don't think that is your problem since they were probably installed at the factory and would have made that noise since the beginning.
