A harmonic balancer puller is an essential tool for mechanics and automotive enthusiasts working on engine maintenance. The OTC Harmonic Balancer Puller is widely recognized for its durability, ease of use, and efficiency in removing harmonic balancers, crankshaft pulleys, and other press-fitted components.
This guide explores everything you need to know about the OTC Harmonic Balancer Puller, including its purpose, features, benefits, and step-by-step instructions on how to use it.
What Is a Harmonic Balancer?
A harmonic balancer, also known as a crankshaft damper, is a device attached to the front of an engine’s crankshaft. Its primary function is to absorb and reduce engine vibrations, preventing damage to internal components.
Over time, harmonic balancers may wear out or need removal for engine repairs. Since they are press-fitted onto the crankshaft, a specialized puller tool is required to remove them safely without causing damage.
