The 140-002 cotter plated key is a direct replacement fastener for PowrTwin 3500 50th anniversary equipment. This precision component is a type of machine key, typically a rectangular or square piece of metal that fits into matching keyways cut into a shaft and a hub, such as a gear, pulley, or sprocket. The key prevents relative rotation between the shaft and the hub, ensuring positive drive and torque transmission. Cotter keys are a specific style that may include a head or bend for retention. A worn, sheared, or missing key can cause the hub to slip on the shaft, resulting in loss of drive, erratic operation, and potential damage to both shaft and hub. This replacement key is manufactured to exact dimensional specifications for proper fit in the keyway. The plated finish provides corrosion resistance for long service life. Installation requires proper alignment of keyways and may involve light tapping to seat the key. Regular inspection during maintenance helps identify keys that show signs of wear or shearing.
