    Your harmonic balancer should be replaced at every major overhaul or in-frame. Professional diesel mechanics, service advisers, and fleet managers recommend replacing the harmonic balancer every 500,000 to 750,000 miles or according to OEM service intervals with a genuine Vibratech TVD viscous damper. This small preventative step provides financial returns over time by helping to maintain the operating efficiency and fuel economy of the engine while reducing the risk of downtime.
