Dorman 594-751 Harmonic Balancer

Dorman 594-751 is a direct replacement engine harmonic balancer for select Audi and Volkswagen applications. It is built with a stress-resistant rubber bond to help 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 isolate engine vibration
• Ductile steel construction for added strength and durability
• Serpentine belt pulley design with 13 grooves
• Black finish with 8 mounting holes
• Cross-references Dorman 594-751 with OE-style part numbers 06E105251E and PB1791N for the same application

Detailed Description

This harmonic balancer is engineered for vehicles that rely on stable crankshaft damping and consistent accessory drive operation. The 594-751 uses a rubber isolator bond to reduce vibration transfer, while the steel body supports the demands of daily driving and engine load changes. It is a practical replacement for Audi Q7, A6 Quattro, A7 Quattro, A8 Quattro, Q5, S4, S5, S5 Sportback, SQ5, A5, A4 Quattro, A6, A7, S7, and Volkswagen Touareg applications listed in the fitment data.

Compatible With 2009-2019 Audi A6 Quattro, 2010-2019 Audi S4, and 2011-2020 Audi Q7, this Dorman 594-751 harmonic balancer also serves select 2011-2017 Volkswagen Touareg and other VAG platform vehicles shown below. Use it when replacing a worn crankshaft damper on Audi A6 Quattro or Audi Q7 models that need OE-style vibration control and serpentine belt drive alignment.

What It Helps Address

• Engine vibration felt through the crankshaft and accessory drive
• Cracked, separated, or deteriorated harmonic balancer rubber
• Wobble or imbalance at the front of the engine
• Serpentine belt tracking issues caused by a worn pulley damper
• Noise from a failing crankshaft vibration damper

Installation Notes and Tips

Verify pulley groove count, mounting hole pattern, inside diameter, outside diameter, and depth before installation. Confirm engine code and VIN breakpoints where listed, especially on Audi A5, A5 Quattro, S5, and A8 Quattro applications with VIN-specific notes. Inspect the crankshaft snout, belt condition, and adjacent pulleys during replacement, and follow the vehicle service procedure for torque and alignment.

Quality Assurance

Dorman manufactures this harmonic balancer as a direct replacement part with materials selected for vibration control and durability. The ductile steel construction and bonded rubber isolator are used to support reliable operation in the listed Audi and Volkswagen applications.
