Product Description
The 31256-003 is a main pulley sheave for aircraft flight-control cable routing. This component guides and redirects control cables—such as aileron runs—through the airframe while minimizing friction and wear on cable surfaces. Typically manufactured from aluminum or steel with a grooved wheel design, the pulley mounts to structural brackets using standard aviation hardware.
Installation requires proper alignment and clearance verification per AC 43.13-1B guidance to ensure smooth cable movement and prevent binding during control surface deflection.
