This is a foot control air valve found on many tire changers. This valve is typically found on all the front foot pedals (clamping jaw pedal, tilt tower pedal, bead breaker pedal) and may also be found on the bead blast / tire fill valve as well.. Foot pedal valves are the control center of your tire changer. They are used to activate the clamping cylinders, bead breaker, air inflation system and turntable. You can access the foot pedal valves by removing the covers from the sides of your tire changer and spotting the air valves connected to the foot pedals.. Check the valve fittings and airlines for damage or leaks. Inspect the body of the valve for cracks. Clean any debris around the valve paying close attention to the rod of the valve. Applying a light amount of air tool oil on the rod while cycling the foot pedal will help lubricate the rod seal.. Activate the foot pedals and check the springs or linkages for proper function and adjust as necessary. If you notice excessive leaks in either foot pedal valves, they will need to be replaced (most people notice a crack in the plastic housing or leaking air from the rod). Rebuild kits are difficult to find and replacement of the entire valve is typical..
