PARTS DESCRIPTION
Product Overview
Belt-drive components transfer crankshaft rotation to engine accessories, making belt length, rib profile, and tensioner geometry important. The Belt Tensioner is supplied as a replacement solution for Cummins 6BT diesel engines and is intended for professional repair, maintenance, or rebuilding work.
When replacing this component, matching the application is more important than relying on appearance alone. Where a confirmed reference is available, the supplied part number can be used together with the engine information to check compatibility before shipment.
