We have a high mileage Super Grind 2000 in our shop which recently developed the following condition: when turned on, the motor hums until the wheel is manually spun, then it works fine. Do we need brushes? A capacitor? A T7?
Isnt there a drive belt or some kind of tensioning device that may need tightening?
While I like the idea of using a T-7 to solve the problem ;D I think you can get back in business for wee bit less. First check to see if it is slipping between the drive tire and the motor shaft. To do that, remove the honing wheel and take a look at the rubber drive tire. Turn the machine on and hold a piece of 80 grit sand paper against the tire to clean and freshen the surface. If at that point you can apply considerable pressure to the grindstone without stalling it out, yet it still requires a manual push to get started, the problem is more than likely the capacitor. We have them in stock. Call us at 1-800-872-5489 between 9am and 5pm Central Time. There are a couple of styles and we need to talk to figure out which one you need.
Great-thanks Jeff. I will keep you posted.
