Product Description
AUTOMATIC BELT TENSIONER, HD, DAYCO
Features & Benefits
- Absorbs fan-clutch shock so the loop stays seated on every pulley
- Broad wheel face keeps contact even along the backside for quiet running
- Maintains steady tension from idle through long climbs and fan engagement
- Spring housing carries the load at the pivot through every swing
Dayco Automatic Belt Tensioner
A flat 86.5 mm pulley gives the Dayco Automatic Belt Tensioner, a heavy-duty automatic tensioner, a smooth surface to ride on the back of the serpentine belt. Counter-clockwise spring action keeps pressure on the drive as engine speed rises, falls and loads the accessories. The Dayco 89477 fits Mack CXU, Granite and Pinnacle trucks and Volvo VNL and VNM models running D13 or MP8 power. A weak arm lets the drive slap and squeal, so a fresh one quiets the front of the engine.
