About this part

ATP Engine Harmonic Balancer, Pontiac Bonneville 1992-1991, Trans Sport 1994-1992, 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., auto part parts hub serpentine dorman pioneer crank damper dampener, Engine Harmonic Balancer, ENG HARMONIC BAL, Buick LeSabre 1992-1991, Park Avenue 1992-1991, Reatta 1991, Regal 1992-1990, Riviera 1992-1991, Chevrolet Lumina APV 1992, Oldsmobile 88 1992, 98 1992-1991, Delta 88 1991, Silhouette 1992, Toronado 1992-1991
