Dorman 594-723 Engine Harmonic Balancer

Dorman 594-723 Harmonic Balancer for Ford F-150

Dorman 594-723 is a direct replacement engine harmonic balancer for select Ford F-150 and Lincoln Mark LT applications. It uses a stress-resistant rubber bond to absorb engine vibration, while ductile steel construction adds tensile and impact strength for long-term durability.

Key Features

• Direct replacement harmonic balancer for OE-style fitment
• Stress-resistant rubber bond helps absorb crankshaft vibration
• Ductile steel construction for added strength and durability
• 10-groove pulley design for serpentine drive belt systems
• Black finish with keyway type included in the hub design
• Part number 594-723 for easy identification

Detailed Description

This Dorman harmonic balancer is built for engines that rely on stable crankshaft damping and consistent accessory drive operation. With a 178 mm outside diameter, 31.6 mm inside diameter, and 42.5 mm depth, it is engineered around the listed OE-style dimensions for the 2014-2017 Ford F-150 and 2014 Lincoln Mark LT. The 10-groove serpentine pulley profile supports the factory belt layout, and the ductile steel body helps resist wear from engine load and vibration. If you are replacing a worn balancer on a Ford F-150 or Lincoln Mark LT, 594-723 provides a direct-fit service part built around the original application.

This part cross-references Ford EL3Z6312A for the same application.

What It Helps Address

• Crankshaft vibration transmitted through the front of the engine
• Worn or separated rubber bond in the original balancer
• Accessory drive noise caused by an out-of-balance pulley assembly
• Serpentine belt tracking issues related to balancer wear
• Front-end engine vibration concerns on the Ford F-150 and Lincoln Mark LT

Installation Notes and Tips

Verify pulley groove count, hub dimensions, and keyway alignment before installation. This harmonic balancer does not include a bolt, washer, or center bolt, so reuse or source the correct fasteners separately as required by the vehicle service procedure. Confirm crankshaft and accessory drive condition during replacement, and inspect the serpentine belt system for wear before reassembly.

Quality Assurance

Dorman builds this balancer with a rubber isolator bond and ductile steel construction to support vibration control and durability in demanding engine service. Part number 594-723 is a direct replacement option for select Ford and Lincoln applications, including the 2014-2017 Ford F-150 and 2014 Lincoln Mark LT.
