Dorman 594-431 Engine Harmonic Balancer

Dorman 594-431 Harmonic Balancer

This Dorman harmonic balancer is a direct replacement for select Hyundai and Kia applications, including Elantra, Elantra GT, Kona, Veloster, Forte, Soul, Tucson, and related models. Part number 594-431 is built to help control crankshaft vibration while maintaining proper belt drive operation.

Key Features

• Stress-resistant rubber bond helps absorb engine vibration
• Ductile steel construction adds tensile and impact strength
• 6-groove pulley design for serpentine belt systems
• Black finish with degree markings for timing reference
• Direct replacement design for OE-style fitment
• Inside diameter: 28.023 mm; outside diameter: 152 mm; depth: 30.2 mm

Detailed Description

The Dorman 594-431 engine harmonic balancer is engineered for vehicles that rely on a serpentine accessory drive and a vibration-damping crank pulley. Its bonded rubber isolator is used to reduce torsional vibration from the crankshaft, while the ductile steel body supports durability under engine load. This makes it a practical replacement for Hyundai Elantra and Kia Forte applications where stable belt tracking and accurate timing reference matter.

This part cross-references OE-style replacement numbers such as 231242E000 and PB1762N for the same application.

What It Helps Solve

• Crankshaft vibration transmitted through the accessory drive
• Worn or separated harmonic balancer rubber bond
• Belt tracking issues on serpentine drive systems
• Timing reference visibility concerns from a faded or damaged balancer
• Noise or imbalance caused by a deteriorated crank pulley assembly

Installation Notes and Tips

Verify pulley groove count, inside diameter, and depth against the original part before installation. Confirm the crankshaft mounting interface and timing mark alignment on the engine. Because bolt and washer are not included, reuse or source the correct fasteners separately as required by the vehicle application. Inspect the serpentine belt and adjacent drive components during replacement to avoid repeat service.

Quality Assurance

Dorman manufactures this harmonic balancer as a direct replacement component with ductile steel construction and a stress-resistant rubber bond for vibration control and durability.
