AFA has announced the availability of a new belt tensioner for the Cummins B/ISB/QSB Series engines.
The belt tensioner, AFA Part No. A3937553, uses the highest quality bearing assembly and superior casting using a high-tension spring coupled with the newest design idler pulley that gives the engine the right amount of tension on the serpentine belt, resulting in noise-free and belt-saving operation, the company says.
