Product Description
The Redmax 514257501 piston pin is a genuine OEM engine component designed to provide a precision connection between the piston and connecting rod in compatible Redmax and Husqvarna handheld outdoor power equipment. Engineered to exact OEM specifications, this hardened steel pin ensures smooth reciprocating motion and reliable durability under high-temperature and high-load conditions. Installing a correct piston pin helps maintain proper engine performance, reduce wear, and support long-term reliability.
What is this part & what does it do?
The piston pin, also known as a wrist pin or gudgeon pin, connects the piston to the connecting rod inside the engine cylinder. It allows the piston to pivot as it moves up and down during combustion. A properly fitted OEM piston pin is critical for controlled engine motion, vibration reduction, and long engine life. Worn or incorrect pins can lead to engine noise, reduced compression, and premature wear of engine components.
