Detailed Description

This Dorman engine harmonic balancer is built for 1993-2001 Honda Prelude models and is engineered to replace the original unit with the correct fit and function. The balancer’s rubber isolator is formulated to resist stress while helping absorb torsional vibration from the crankshaft, which is important for smooth engine operation and accessory drive stability. With a 166.9 mm outside diameter, 30.04 mm inside diameter, 66.6 mm depth, and 4-groove serpentine pulley layout, 594-581 matches the needs of the application without unnecessary changes to the engine setup. This part cross-references Honda OE numbers 13810P13003 and 102373 for the same application.

What It Helps Address

• Engine vibration felt through the crankshaft and accessory drive
• Worn or separated harmonic balancer rubber bond
• Noise or imbalance from a deteriorated crank pulley assembly
• Accessory belt tracking issues related to balancer wear
• Fitment problems caused by an incorrect replacement balancer

Installation Notes and Tips

Verify crankshaft and pulley dimensions before installation, and confirm the keyway alignment matches the original setup. Inspect the serpentine belt, crank bolt area, and surrounding front-engine components for wear before reassembly. Because mounting hardware is not included, reuse or source the correct hardware separately as needed. For fitment, this part fits 1993-2001 Honda Prelude, N/A.
