ATP Harmonic Balancer 102028

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., ENG HARMONIC BAL, Ford Aerostar 1997-1990, Explorer 2002-1991, Explorer Sport Trac 2003-2001, Ranger 2003-1990, Mazda B4000 1996-1994, Navajo 1994-1991, Mercury Mountaineer 2002-1998, ATP Engine Harmonic Balancer, auto part parts hub serpentine dorman pioneer crank damper dampener, Engine Harmonic Balancer
