The Kyosho 74033-06 Piston Pin is a key replacement part for RC models running the KE15SP engine. It fastens the piston to the connecting rod so the engine converts combustion force into smooth crank movement.
Specifically matched to the KE15SP engine, this piston pin is a direct fit for platforms such as the FW06. Using the correct OEM-style pin helps maintain original engine geometry and performance under load.
Regularly check the pin for wear, fretting, or distortion and replace it if any defect is visible. Ensure proper lubrication and clean mating surfaces during assembly to reduce wear when operating in dusty or harsh conditions.
