CATERPILLAR® Viscous Harmonic Balancer from Vibratech 716405-000

Upgrade your Caterpillar diesel engine’s performance with the genuine Vibratech 716405-000 Heavy Duty Viscous Harmonic Balancer. Designed as a direct bolt-on replacement and a cross-reference for 7E9520/1678126, this American-made damper is engineered to effectively control torsional vibrations in engines such as the CAT C15, C16, 3406, and 3408. Manufactured in ISO 9001:2008 certified facilities, it features a free-rotating inertia ring surrounded by high-density viscous silicone fluid in a laser-welded, sealed steel housing.

Key Features & Benefits

  • Automatic Vibration Control:
    The viscous damper self-tunes in real time to minimize crankshaft torsional vibrations, ensuring smooth engine operation.
  • Direct Bolt-On Replacement:
    Precision-engineered for an exact fit, reducing downtime and installation hassles.
  • American Made Quality:
    Proudly manufactured in the USA with ISO-9001 quality control.
  • Enhanced Engine Performance:
    Increases horsepower and torque, improves fuel efficiency, and extends engine life.
  • Durability & Reliability:
    Reduces wear on bearings, gears, and other vital engine components while improving valve timing and smoothing engine idle.
  • Low Maintenance & Eco-Friendly:
    Sealed design requires no maintenance and is designed for proper recycling.

Applications

This heavy-duty vibration damper is ideal for various Caterpillar diesel engine models, including:

  • Caterpillar C15 (excluding SDP series engines produced from 2008 to 2010)
  • Caterpillar C16
  • Caterpillar 3406 (all versions: A, B, C, E, PC)
  • Caterpillar 3408

It is perfect for applications in industrial, construction, agriculture, mining, and mobile earth-moving equipment where reliable vibration control is essential.

Replacement & Service Intervals

For optimal engine performance and to prevent catastrophic damage, replace your harmonic balancer at the recommended interval of 350,000 to 500,000 miles. Timely replacement is crucial- especially after an engine overhaul- to avoid excessive wear, bearing failure, or crankshaft damage.

Additional Information

  • Precision Manufacturing:
    CNC-machined parts and a laser-welded, sealed housing ensure the highest standards of performance and durability.
  • Cost-Effective:
    Avoid the pitfalls of cheaper, overseas alternatives that can compromise your engine’s integrity.
  • Important Note:
    This damper does not fit the SDP versions of CAT C15 ACERT diesel motors (2008–2010). Always verify compatibility before purchase.

Enhance your engine’s efficiency, reduce maintenance costs, and ensure long-term reliability with the Vibratech 716405-000 Heavy Duty Viscous Crankshaft Damper- the smart choice for superior vibration control and power transmission.

  • FAQ: When should the crankshaft damper be replaced?

    Over time on a heavy-duty engine, the recommended change interval for most motors is 500,000 miles or 15,000 hours of run time. Your OEM damper silicone begins to revert from its original state to a solid. As this progresses, the silicone becomes thicker, and the reaction time or shearing of the inertia ring decreases. The reduction of crankshaft damper performance diminishes with age. This degradation negatively affects the damper's ability to absorb the different engine harmonics throughout its entire RPM operating range. How can I tell when the engine damper requires replacement? Excessive wear of engine bearings, Excessive wear of accessory drive gears, Cracked or broken attachment brackets, Loosening of bolts and fasteners, Throwing or slapping belts, A decrease in engine horsepower and torque, Reduced fuel economy, Annoying Vibrations, Increased driver fatigue, The engine is loud, and you feel increased vibrations levels, The serpentine pulley belt may be slipping.
