GM Harmonic Puller Tips

A GM harmonic or harmonic balancer is a piece of equipment that absorbs the vibrations produced by a GM engine. It is engineered with a tough metal exterior, but a small portion of its interior is manufactured from rubber. This material is likely to wear over time and through extensive use, so a GM harmonic puller is a specialist tool required to remove and replace the existing harmonic balancer with a new one.

Use a GM Harmonic Balancer Puller Set

The task of removing a damaged or worn harmonic balancer from a vehicle is difficult, so using the correct tooling is crucial. A harmonic balancer puller set includes several specialist tools and fittings that can be used to assist each stage of the application. This set can also be used to remove and restore gear pulleys, as well as to adjust steering wheels. It includes hardened steel forcing screws and numerous sets of washer head bolts, along with the standard puller with fortified jaw design. This set allows users to remove a harmonic balancer effectively and in a time effective manner.

Use a GM Brand Harmonic Puller

Automotive manufacturers utilize different engine designs in their vehicles, so it is wise to use brand specific tools when performing repairs or restoration. A GM harmonic puller is designed to remove GM and Chrysler equipment, and is therefore specifically manufactured to use on certain engines. This particular tool has a special three-jaw puller design that is both compact and robust, and can work in tight GM engine spaces without the need for removing the radiator. It can also be used with tailored lengths of forcing rods and suitably-sized forced screws. Using the correct tool also helps protect otter components within the engine from damage.

Use Suitable Bolts to Attach the Harmonic Balancer Puller

During the removal process, a pulley is removed from the face of the harmonic balancer. Once this is complete, it is often the case that the bolts that held it in place are not suitable for use with the puller tool. Ideally, the puller is connected to the harmonic balancer using these bolts, but they may not be long or thick enough to be gripped efficiently by the puller. In this instance, specific bolts are available that are compatible with the tool, and leave at least a half inch of length to be fitted securely to the harmonic balancer. This ensures that the tool can be attached and the harmonic balancer can be moved accordingly.
