1234031-2 – Textron Aviation OEM Sleeve Bushing
Available now on the Airparts.aero Marketplace.
Overview
The 1234031-2 is a genuine Textron Aviation (Cessna) Original Equipment Manufacturer (OEM) sleeve bushing. This is not a simple spacer; it is a precision-machined bearing component engineered for a specific, likely flight-critical, application within the airframe or systems of Cessna aircraft. Its primary function is to provide a durable, replaceable, low-friction bearing surface for a pivot pin, bolt, or shaft, protecting the surrounding structure from wear and ensuring smooth mechanical operation.
Manufactured to the exact specifications of Textron's engineering drawings, this bushing is fabricated from a specific material (likely a high-quality bearing bronze or heat-treated steel, to be confirmed by OEM documentation) chosen for its strength, wear resistance, and tribological properties. As the genuine OEM part, the 1234031-2 guarantees the precise dimensions required for a proper fit (often a press-fit), ensuring the integrity and longevity of the assembly it is part of.
Key Features
Genuine Textron Aviation OEM Part: Guarantees the part is fabricated to the exact Textron engineering drawing for material, dimensions, hardness, and performance.
Precision Machined Bearing Surface: Provides a smooth, dimensionally accurate surface for rotating or pivoting components, minimizing friction and wear.
Sacrificial Wear Component: Intentionally designed to absorb wear over time, protecting more expensive and complex parent structures (like control linkages, bellcranks, or actuator housings) from damage.
Application-Specific Material: Manufactured from a specific alloy chosen by Textron engineers for the load, speed, and environmental conditions of its intended application.
Ensures Proper Fit and Function: Precision dimensions guarantee the correct interference fit (if press-fit) and internal clearance for the mating pin or shaft.

Door hinges and mechanisms.
Engine control linkages.
Why Choose 1234031-2?
Bushings in aircraft systems are critical wear components. The genuine Textron OEM 1234031-2 is the only part guaranteed to be manufactured from the correct material with the precise dimensions and hardness specified by the original design. Using a non-certified bushing made from an incorrect alloy or with improper dimensions can lead to rapid wear, excessive free play ("slop") in critical systems like flight controls or landing gear, binding, or even failure of the parent component due to incorrect fit or stress distribution.
The engineering function of a press-fit sleeve bushing like the 1234031-2 relies heavily on the principle of interference fit. The bushing's outside diameter is manufactured to be fractionally larger than the inside diameter of the hole in the parent component. During installation using an arbor press, this size difference creates significant radial pressure between the bushing and the housing bore. This pressure induces high frictional forces that securely lock the bushing in place, preventing it from rotating or moving axially within the housing during operation. This interference fit is precisely calculated based on the materials' coefficients of thermal expansion, moduli of elasticity, and the expected operating loads. A correct interference ensures the bushing acts as a stable, integrated bearing surface. However, this process also causes the bushing's inside diameter to contract slightly. Therefore, after installation, the bushing typically requires reaming to its final, precise inside diameter to achieve the specified running clearance for the mating pin or shaft, ensuring low-friction operation without excessive play.
Note: This is a flight-critical component, often used in primary flight control or landing gear systems. It is typically a wear item subject to periodic inspection. Removal of the old bushing and installation of the new one are press-fit operations requiring specialized tooling and must be performed by a certified A&P mechanic per the aircraft maintenance manual. The inside diameter must be reamed to its final specified dimension after installation.
