What is the purpose of this crank pin drill kit?

This kit is used to drill a hole in the crankshaft snout and the crankshaft pulley. This allows for a pin to be installed, which physically locks the pulley to the snout, preventing it from spinning independently.

Why is pinning the crankshaft pulley important on these Hemi engines?

On high-performance Hemi engines, especially those with VVT or superchargers like the Hellcat, the torque and stress can cause the crankshaft pulley to spin on the crank snout. This can lead to timing issues and severe engine damage. Pinning provides a mechanical lock to prevent this.

What tools are typically needed to install this kit?

You will need a drill, appropriate drill bits (included in the kit), and likely a way to accurately measure and align the pulley and crank snout. Always refer to the manufacturer's instructions for the most accurate tool list and procedure.

Product Details

This is the ATI Crank Pin Drill Kit, specifically made for Hemi engines. It's designed for the 5.7L, 6.1L, and 392 cubic inch Hemi engines from 2009 and newer that feature VVT, as well as the high-performance 6.2L Hellcat and Demon engines. This kit is essential if you're looking to properly secure your crankshaft pulley, preventing it from spinning on the crank snout, which is a common failure point on these powerful engines.

ATI is well-known for their robust performance engine components, and this drill kit is no exception. It includes the necessary drill bits and fixtures to accurately create a pilot hole for a pin. This process ensures that your crankshaft pulley stays firmly in place, even under the extreme stress these engines can generate. Proper installation of this kit is crucial for maintaining the integrity of your engine's timing and preventing catastrophic damage.

When working on these high-output Hemi engines, attention to detail is key. This kit provides a reliable method for a critical modification that many builders opt for to add an extra layer of security to their build.
