Dorman 594-731 Engine Harmonic Balancer

Direct Replacement Harmonic Balancer

Dorman 594-731 is a direct replacement harmonic balancer built to absorb engine vibration and support smooth crankshaft operation. It uses a stress-resistant rubber bond and ductile steel construction for durability in demanding engine service.

Key Features

• Direct replacement design for the original harmonic balancer
• Stress-resistant rubber bond helps absorb engine vibration
• Ductile steel construction adds tensile and impact strength
• Serpentine belt application with 6 pulley grooves
• Black finish with regular grade construction

Detailed Description

This Dorman harmonic balancer, part number 594-731, is engineered for engines that use a serpentine drive belt and a 6-groove pulley layout. The rubber isolator is designed to reduce vibration transfer, while the ductile steel body adds strength where the balancer is exposed to repeated load and rotational stress. It is a direct replacement for applications that require the same dimensions and mounting layout, including Ford Fiesta and Ford Fiesta Ikon fitments listed below. Cross-reference part numbers include BE8Z6312A and PB1755N for the same application.

What It Is Used For

• Reduces engine vibration transmitted through the crankshaft
• Addresses worn or deteriorated rubber bond material
• Replaces a damaged or out-of-balance harmonic balancer
• Supports proper serpentine belt drive operation
• Helps restore smooth engine rotation and accessory drive performance

Installation Notes and Tips

Verify inside diameter, outside diameter, depth, mounting hole diameter, and pulley groove count before installation. Confirm the engine uses a serpentine belt layout and matches the listed fitment for Ford Fiesta 2011-2018 and Ford Fiesta Ikon 2014-2015. Inspect the crankshaft snout, keyway configuration, and mounting surfaces for wear or damage before fitting the balancer.

Quality Assurance

Dorman manufactures replacement components with application-specific dimensions and construction intended to match original equipment requirements. Part number 594-731 is built with ductile steel and a stress-resistant rubber bond for durability in engine service.
