Product Details

The harmonic balancer mounts to the crankshaft hub and uses an internal damping layer to reduce torsional vibration. Over time, the damping material can deteriorate, allowing the outer pulley section to shift and throw the belt system out of alignment. When that happens, the balancer should be replaced to help restore normal engine operation. ATP Parts 102275 is built as a direct OE-style replacement for the Honda Accord, Honda Odyssey, Honda Pilot, Acura CL, Acura TL, and Acura MDX applications listed above.

This part cross-references Pioneer Automotive Industries DA-3490 for the same application.

Common Problems This Part Can Address

• Crankshaft vibration at idle or under load
• Belt misalignment on serpentine drive systems
• Visible wobble or separation at the balancer
• Noise from the front of the engine
• Wear related to a deteriorated harmonic balancer damping layer

Installation Notes

Verify pulley groove count, outer diameter, and engine application before installation. Inspect the crankshaft snout, keyway, and belt drive components for wear or damage before fitting the new balancer. Use the correct service procedure and torque specifications for the vehicle, and confirm belt tracking after installation.

Quality Assurance

ATP Parts OE Replacement Balancer 102275 is engineered to fit and function like the original component, helping restore the engine’s vibration control and belt drive operation on the listed Acura and Honda applications.
