Product Details

The harmonic balancer sits on the crankshaft and helps absorb engine vibration through an internal damping layer. Over time, the rubber or fluid element can deteriorate, allowing the outer pulley section to shift and throw the belt system out of alignment. ATP Parts 102256 is engineered as a standard replacement for the original balancer, helping restore normal engine operation on compatible Honda Civic and Honda Accord vehicles. This part cross-references Pioneer Automotive Industries DA-224 for the same application.

Installation Notes

Verify the groove count, outer diameter, and depth against the original balancer before installation. Inspect the crankshaft snout, belt routing, and adjacent pulleys for wear or damage, since a failed balancer can affect the entire drive system. Confirm the application details for your Honda Civic or Honda Accord, including the listed double serpentine configuration, before ordering ATP Parts 102256.
