Dayco 89035 No Clack Idler Tensioner Pulley is a 95 mm diameter V-groove pulley designed for use with a 3/8" belt and featuring a 12 mm bearing. As an idler tensioner, it guides the belt and maintains tension in belt-drive assemblies to help prevent slip and misalignment. The V-groove profile provides proper seating for a 3/8" belt, while the 12 mm bore supports mounting to a shaft or bracket for reliable operation. Dayco's 89035 component is intended for belt-drive configurations that require a No Clack idler tensioner with a 3/8" belt and a 95 mm diameter pulley.
