The part number 594-766 is a practical OE-style replacement for service work where vibration control and pulley alignment matter.

What It Helps Address

• Engine vibration felt through the crankshaft and accessory drive
• Cracked or deteriorated harmonic balancer rubber bond
• Wobble, noise, or imbalance at the front of the engine
• Timing reference visibility during service checks
• Wear on the serpentine belt drive caused by a failing balancer

Installation Notes and Tips

Verify crankshaft diameter, pulley groove count, and keyway style before installation. Inspect the crankshaft snout, belt alignment, and surrounding front-engine components for wear or damage before fitting the new balancer. Because the center bolt and washer are not included, reuse or source the correct fasteners separately as required by the vehicle service procedure. Confirm timing marks are aligned after installation.

Quality Assurance

Dorman builds this harmonic balancer as a direct replacement part using ductile steel and a vibration-absorbing rubber bond to support dependable service in Honda and Acura applications.
