Flywheel Dowel Locating Pin

The Flywheel Dowel Locating Pin (MPN 10046031) is a precision-engineered fastener designed for ensuring proper flywheel alignment during engine assembly and rebuilds. This small but critical component serves as a positioning reference, preventing misalignment that could lead to vibration, noise, and drivetrain stress. It is suitable for use in both small-block and big-block Chevy engines, making it a versatile choice for various automotive applications.

Dowel pins function as mechanical indexing devices that locate the flywheel relative to the crankshaft flange with precision. This component maintains dimensional consistency across multiple engine applications, ensuring that the clutch disc, pressure plate, and flywheel assembly remain properly aligned. The importance of this pin cannot be overstated, as improper alignment can result in clutch chatter, premature wear, and expensive bearing damage.

Technicians and engine builders often install replacement dowel pins during complete engine overhauls, transmission swaps, or when refurbishing late-model LS engines and classic small-block platforms. This pin is a crucial component for anyone looking to ensure the reliability and performance of their engine assembly. By using this high-quality part, you can help prevent potential issues related to misalignment.
