Any Coats tire changer troubleshooters/technicians on board....
 

Guys, I got a good deal on a refurbished Coats 5060 tire changer. Now, I know why.....it leaks so much air my huge air compressor cannot keep up. Not ever having used one, need some help in identifying the problem.

In looking over the parts breakdown manual, the air leak appears to be coming from the "mufflers" on the four way valve that is under and part of the "BL" cylinder. This is the cylinder that activates the bead breaker rod on the side of the unit. This valve is activated by the small push button on the bead breaker handle.

Question is , is the four way valve bad or is it the O rings and seals bad on the BL cylinder and allowing it to leak thru the "mufflers" . I can find several folks on flea bay selling seal kits to rebuild the this cylinder but am not sure which part is the culprit......thanks......

I would think it would be the valve. The cylinder only gets air pressure when the valve opens. If it were the cylinder, it would only leak when the valve is activated.

I have a hunter changer in my shop. There are a lot of those coats machines around.

Thanks 95, I will check and see if that valve is serviceable and who may have the parts. I need that thing to work. I live in a very small town....any idea of how to find a repair pro that would make a house call if I am not able to find whats needed.....
