ATP Harmonic Balancer 102122

About this part

The purpose of an harmonic balancer is to absorb crankshaft vibrations. Harmonic balancers are typically constructed in three pieces. The first piece is often called a hub. It bolts to directly to the crankshaft. The hub is surrounded by rubber or fluid which dampens crankshaft vibrations. The outside layer is metal which has grooves on it for the belt. Over time the rubber and/or fluid layer deteriorate causing the outer pulley to shift forward. This causes belt miss alignment and can ultimately result in crankshaft failure. When the harmonic balancer is broken, it must be replaced. ATP Harmonic Balancers fit and function just like the original part restoring the engine to normal operation., Firebird 1979-1977, Grand LeMans 1977, Grand Prix 1977, Grand Safari 1978-1977, LeMans 1977, Phoenix 1977, Ventura 1977, Engine Harmonic Balancer, ENG HARMONIC BAL, ATP Engine Harmonic Balancer, auto part parts hub serpentine dorman pioneer crank damper dampener, Buick Century 1977, Electra 1978-1977, Estate Wagon 1978-1977, LeSabre 1978-1977, Regal 1977, Riviera 1980-1977, Skylark 1977, Cadillac Brougham 1987, Brougham 1990-1989, Eldorado 1979, Seville 1978-1976, Oldsmobile 98 1978-1968, 442 1971-1968, Custom Cruiser 1978-1971, Cutlass 1977-1968, Cutlass Calais 1984, Cutlass Salon 1977-1975, Cutlass Salon 1986-1985, Cutlass Supreme 1977-1971, Cutlass Supreme 1984, Cutlass Supreme 1987, Cutlass Tiara 1976, Delta 88 1978-1968, F85 1972-1968, Omega 1974-1973, Omega 1977, Toronado 1979-1968, Vista Cruiser 1975-1968, Pontiac Bonneville 1978-1977, Catalina 1978-1977
