When an accessory drive wobbles or squeals at startup, the Dayco Automatic Belt Tensioner can replace a tired spring-loaded arm on a compatible system. Its 74 mm pulley helps guide the belt while spring pressure follows changes in load and engine speed. As the arm moves, it maintains contact between the ribs and their grooves instead of leaving slack in the loop. The Dayco 89483 restores the tensioning action that a worn pivot or spring may no longer provide.
