Rebuilding Harmonic Balancers
We specialize in rebuilding harmonic balancers , especially the rare and hard to find models.
We also rebuild the harmonic balancers for more common engines. Since we rebuild your harmonic balancer and return it, you keep your original harmonic balancer core (which is important to some people).
I rebuild your harmonic balancer within three business days and return to you; but usually I can complete the harmonic balancer rebuild in only two days.
With over 33 years of harmonic balancer rebuilding experience, your can rest assured that the job will be done right (I do all the work myself to insure high quality). I offer a 'life time' guarantee that the rubber will not fail on your harmonic balancer, or I correct the problem at no cost. This harmonic balancer guarantee continues even if your sell your car.
(the harmonic balancer guarantee is probably limited only by the length of my life!)
Please follow the links above to get full information, prices, and harmonic balancer models I have already rebuilt. If yours is not on my list, please call and we can discuss what information I will need to succesfully rebuild your harmonic balancer. (503 364-8685 PST )
. Harmonic Balancers (also known as vibration dampeners [ dampers] or pulleys) are fitted to the crankshafts of some engines in order to control the torsional (twisting) vibration of the crankshaft. The need for a Harmonic Balancer often stems from increasing the stroke of the engine which makes the crankshaft overly flexible (twisty). If something is not done to keep this flexing vibration to less than 1/2 of one degree of twist from one end of the crankshaft to the other, then the crankshaft may develop cracks over time.
. The harmonic balancer consists of the hub (bolted to the crankshaft), an outer weight ring (usually of cast iron) and a sandwiched layer of flexible rubber.
. This rubber absorbs the energy of the vibrating crankshaft in the form of heat, damping the amount of vibration to within safe limits. The rubber may deteriorate from heat, becoming hard and brittle, or from oil it may begin to soften and decompose. Also often times the rubber begins to move out between the parts so that it no longer provides the proper frequency to dampen crankshaft twisting vibration.
. We replace this rubber strip with modern high-temperature black silicone mold making rubber, restoring its function of protecting your engine from excess vibration and crankshaft failure.
