Introduction to Roll Pins

Roll pins are fundamental mechanical fasteners used extensively in automotive and heavy-duty truck industries. These cylindrical pins secure components together by friction and shear strength, providing stability and alignment in various applications. Their role is indispensable in ensuring that parts remain in proper alignment and function efficiently ¹.

Function and Mechanism of Roll Pins

Roll pins, also known as cotter pins, operate by being inserted into a hole or slot in one of the components. Once in place, they are deformed slightly, creating a secure fit that prevents relative motion between the parts they connect. This method ensures that the parts remain aligned and in position, which is crucial for the efficient operation of truck engines. The friction and shear strength provided by roll pins are essential for maintaining the integrity of the engine’s moving parts ².

Purpose of Cummins Part #3070475

The Cummins part #3070475 is a specific type of roll pin designed for use in engines. Its primary role is to maintain the alignment and stability of moving parts within the engine. By doing so, it ensures that the engine operates smoothly and efficiently, reducing wear and tear and extending the lifespan of the engine components. This particular roll pin is engineered to meet the demanding requirements of heavy-duty engines, providing reliable performance under extreme conditions ³.

Role in Truck Operation

In the context of a truck engine, the roll pin ensures that critical components such as gears, shafts, and pulleys remain properly aligned. This alignment is essential for the transmission of power and the smooth operation of the engine. Without a properly functioning roll pin, there could be increased friction, misalignment, and eventual failure of the connected parts, leading to costly repairs and downtime. The Cummins part #3070475 plays a vital role in preventing such issues, ensuring that the engine operates at peak efficiency ⁴.
