What NHTSA recorded

Mack is recalling 66 my 2009 gu trucks equipped with bendix mv-3 dash control valves. The molded valve body has an incorrect core pin in the injection mold causing the valve body to be oversized in the double check valve area. This condition can allow the rubber double check valve to become lodged in the body opening under certain circumstances.

Possible consequence

If the double check valve becomes lodged, in the event of a primary reservoir failure, air pressure can leak past the lodged double check valve thereby depleting the secondary reservoir, causing reduced ability for modulating the service emergency brakes increasing the risk of a crash.

Remedy

Dealers will inspect the mv-3 dash valve for the production date code. Valves in the affected production lots will be replaced free of charge. The recall began on may 9, 2008. Owners may contact mack trucks at 1-800-528-6586.
