How to Remove a Harmonic Balancerby John Stevens J.D.
A harmonic balancer is a devise that attaches to the front end of an engine's crankshaft and is used to reduce the vibrations produced by an engine. Reducing the engine's vibrations is vital to the life of an engine. Installing a harmonic balancer is a relatively simple task, but removing one can be challenging without the proper tools. Although harmonic balancers rarely need replacing, removal is necessary to access other engine parts, such as the timing chain, camshaft and front engine seal. Follow the steps below to properly remove a harmonic balancer.
Locate the large metal piece from the harmonic balancer removal kit. This piece looks like the webbing on the foot of a duck, and is therefore commonly referred to as a "duck's foot."
Thread the large threaded rod included with the removal kit through the center of the duck's foot. Note that one side of the duck's foot is flat while the other side is curved. The flat side faces the engine. Therefore, the threaded rod should be threaded into the curved side of the duck's foot.
Locate the three bolts for the harmonic balancer included in the kit. These bolts will thread through the three holes that surround the face of the balancer itself.
Insert each bolt through the slotted portions of the duck's foot.
Use a wrench to secure each of the three bolts through the three holes of the balancer. Secure the bolts by turning the bolts in a clockwise direction. Securing these bolts will attach the harmonic balancer puller to the harmonic balancer.
Locate the bolt-head on the end of the threaded rod that was inserted through the puller earlier.
Remove the harmonic balancer by attaching a wrench to this bolt-head and slowly turning the threaded rod in a clockwise direction. By turning the threaded rod, the puller will slowly pull the balancer until it has been removed from the engine.
