Detailed Description

A harmonic balancer uses a hub, damping material, and outer pulley ring to reduce crankshaft vibration and keep accessory drive alignment stable. Over time, the damping layer can deteriorate, allowing the outer ring to shift and creating belt misalignment, noise, and added stress on the crankshaft. ATP Parts 102272 is made to replace the original balancer and restore normal engine operation on applications such as Ford F-150, Ford Explorer, and Mercury Grand Marquis.

This part cross-references Pioneer Automotive Industries DA-2805 for the same application. It also interchanges with OE references including 1W7Z-6312-A and 594311.

What It Helps Fix

• Crankshaft vibration from a worn balancer
• Serpentine belt misalignment
• Noise from a shifting outer pulley ring
• Accessory drive stress caused by harmonic imbalance
