HB1283N Powerbond Harmonic Balancer

The HB1283N Powerbond Harmonic Balancer is a premium OEM replacement component designed to suit Ford 4.0L SOHC 6-cylinder engines, specifically found in models such as the Ford Falcon EF (including XR6), Fairlane NF, and Fairmont EF, manufactured between 1994 and 1996. Engineered for durability and precision, this harmonic balancer plays a vital role in maintaining engine smoothness and protecting the crankshaft from damaging torsional vibrations.

⚙️ Function & Performance A harmonic balancer is essential for absorbing the twisting forces generated by the crankshaft during engine operation. The HB1283N uses bonded dampening rubber, which significantly improves resistance to spinning and dislocation compared to traditional press-in rubber designs. In torque and push-apart tests, Powerbond’s bonded design has shown up to four times the strength of conventional balancers, making it ideal for engines running serpentine belt systems or operating under high stress.

🛠️ Construction & Materials Crafted from high-grade SG (spheroidal graphite) iron castings, the HB1283N offers superior strength and crack resistance compared to cheaper grey iron alternatives. This ensures long-term reliability, even in demanding driving conditions. The balancer is also dynamically balanced at the factory. This helps reduce vibration and wear on surrounding components, contributing to smoother engine operation.

📐 Specifications & Fitment

• Crank bore diameter: 31.73 mm
• Nose diameter: 44.43 mm
• Outside diameter: 174 mm
• Overall width: 74 mm

These dimensions ensure a precise fit for the specified Ford models, maintaining factory alignment and belt tension. The HB1283N sells as a complete new assembly. Meaning no core return or deposit requires. Making it a convenient and cost-effective solution for engine rebuilders and repairers.

🚗 Applications & Value This balancer is compatible with a range of Ford EF-series vehicles equip with the 4.0L Intech SOHC 12-valve MPFI engine. Including sedans and wagons. It’s a popular choice for both standard maintenance and budget performance builds, including “claimer motor” circle track racing applications.

In summary, the Powerbond HB1283N Harmonic Balancer combines robust materials, advanced dampening technology, and precise engineering to deliver exceptional performance and reliability. Whether you’re restoring a classic Ford or maintaining a daily driver, this balancer ensures smooth operation and long-term durability.
