The Cummins 3063734 Plain Woodruff Key is a specialized component designed for use in heavy-duty truck engines. Its purpose is to secure various components onto shafts, ensuring they remain in place under operational conditions. This key plays a role in maintaining the integrity and performance of truck engines by facilitating secure connections between rotating parts ¹.

Basic Concepts of Plain Woodruff Key

A Plain Woodruff Key is a type of key used in mechanical systems to prevent relative rotation between a shaft and the components mounted on it. It is characterized by a semi-circular cross-section that fits into a matching groove cut into the shaft. This design allows for a secure fit that resists both axial and torsional forces, ensuring that components remain aligned and operational ².

Purpose of Cummins 3063734 Plain Woodruff Key

The Cummins 3063734 Plain Woodruff Key serves to secure components such as gears, pulleys, and sprockets onto the shafts within a truck’s engine. By fitting into a groove on the shaft and mating with a corresponding slot in the component, it ensures that these parts do not rotate independently of the shaft. This function is vital for the synchronized operation of engine components, contributing to the overall efficiency and reliability of the truck ³.

Key Features

This Cummins part is crafted from high-quality materials to ensure durability and performance. Its design includes precise dimensions that allow for a snug fit within the shaft and component grooves.
