Toyota 4Runner Harmonic Balancers

A harmonic balancer, also known as a harmonic damper, is designed to ensure the smoothness of engine operation. The harmonic balancer is mounted on the accessory drive end of the crankshaft and works countering the forces that appear due to uneven power impulses from the pistons. In comparison with the balance shaft, the harmonic damper is a simple device that doesn’t lead to significant power losses and engine design complication, which ensures its extensive use in the automotive world and beyond. And Toyota’s engines are no exception.

With the crankshaft length increasing, the role of the harmonic balancer becomes more significant. In large engines with six or more cylinders, especially with cross-plane cranks, the use of a harmonic balancer becomes a vital necessity. Toyota’s 4Runner lineup has been using harmonic balancers in all of its generations, so there is every likelihood that you have such a device in your SUV. And you should take care of it since an impaired balancer cannot function properly while contributing to the vibrations of the engine and shortening the service life of the crankshaft.
