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., Buick LeSabre 1975, Oldsmobile 98 1975, Custom Cruiser 1975, Delta 88 1975, Pontiac Bonneville 1978-1968, Catalina 1978-1968, Executive 1970-1967, Firebird 1979-1968, Grand Am 1975-1973, Grand LeMans 1977-1975, auto part parts hub serpentine dorman pioneer crank damper dampener
