The 481-613 is a Piper OEM aircraft control cable pulley used to guide and route flight control cables within the airframe. It is designed to provide smooth directional changes in cable routing while minimizing friction, wear, and loss of control efficiency.

In Piper aircraft applications, pulleys such as the 481-613 are commonly used in primary flight control systems (ailerons, elevators, rudder) as well as secondary systems such as trim or flap cable routing, depending on aircraft model configuration. The pulley ensures that control cables follow the correct path through the airframe while maintaining proper tension and alignment.

The pulley wheel rotates on a bearing or bushing system mounted within a bracket assembly, allowing smooth and consistent operation under load. This reduces cable abrasion and helps maintain precise control response throughout the aircraft’s operating range.

Manufactured to Piper OEM specifications, the 481-613 is typically constructed from aircraft-grade aluminum alloy or steel, with a precision-machined cable groove designed to match standard aviation control cable diameters. The bearing system is engineered for low friction, long service life, and reliable performance in vibration-heavy environments.

Because it is part of the primary flight control system, condition and alignment are critical. Wear in the groove, bearing roughness, or misalignment can increase friction and negatively affect control feel and system reliability.
