Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Damper, Vibration: Description
The crankshaft damper is used to control the resonance that is produced by the engine. The Noise, Vibration, and Harshness (NVH) created from the crankshaft can be controlled by dissipating the torque energy through the damper.
The crankshaft damper is held to the crankshaft by means of a hardened steel bolt. The damper is pressed onto a specific machined surface of the crankshaft.
The HEMI® Engines incorporate various crankshaft vibration dampers depending on the engine application.
Finding the proper puller for the application will ensure no damage will come to the damper. The flange puller is used by installing three bolts into the pre-tapped holes in the damper.
Some pulleys (1) that do not have bolt holes can be removed with a three jaw style special tool # 1023, (Puller) (3).
