Product Details

This Dorman harmonic balancer is engineered for engines that need stable crankshaft vibration damping and reliable accessory drive operation. The rubber isolator bond helps manage torsional vibration, while the ductile steel body adds durability under engine load.

This part cross-references PowerBond by Dayco PB1377N for the same application.

Common Problems It Can Help Address

• Crankshaft vibration from a worn balancer
• Visible rubber separation or deterioration
• Accessory drive wobble or belt tracking issues
• Timing reference wear on the original balancer
• Noise or imbalance related to a failing harmonic damper

Installation Notes

Verify inside diameter, outside diameter, depth, groove count, and mounting configuration before installation. Use the included instruction sheet and confirm proper alignment of the Woodruff key and degree markings during setup. Because this application uses a serpentine belt system, inspect the belt path and related pulleys before final assembly.
