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 on the engines is held to the crankshaft by means of a harden 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. And can be removed depending on the application used.
Finding the proper puller for the application will ensure no damage will come to the damper. The flange puller is used by installing 3 bolts into the pre-tapped holes in the damper.
Some pulleys that do not have bolt holes can be removed with a three jaw style (special tool #1023, Puller).
