1555014-2 – Textron Aviation Cessna OEM Riser Half Clamp

Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 1555014-2 is a genuine OEM riser half clamp, a flight-critical piece of hardware designed to support the exhaust system on a wide range of Cessna single-engine aircraft. This component is precision-stamped from high-temperature stainless steel and is used in pairs to form a complete clamp assembly. Its sole function is to securely fasten the individual exhaust riser tubes to each other and to support brackets, preventing the entire system from cracking under the intense, high-frequency vibrations of the engine. As a genuine Textron OEM part, it guarantees the precise fit and material strength required for this demanding application.

Key Features

• Vibration Suppression & Support: The primary function is to rigidly support the exhaust stacks, preventing the tubes from vibrating independently. This dramatically reduces stress at the cylinder head flanges and welded joints, which are the most common points of failure from metal fatigue.
• High-Temperature Stainless Steel Construction: Fabricated from a high-grade, corrosion-resistant stainless steel alloy. This material is chosen for its ability to maintain its tensile strength and resist cracking at the very high temperatures found in the engine compartment, immediately adjacent to the exhaust tubes.
• Precision Stamping: Each clamp half is precision-stamped to the exact curvature and dimensions required to snugly fit the exhaust risers on specified Cessna models, ensuring a secure grip without crushing or deforming the tubes.
• Two-Piece Assembly: Designed to be used as a matched pair (two 1555014-2 clamp halves are required per clamp location) along with specified bolts and nuts to create a complete, robust clamping assembly.
• Genuine Textron OEM Part: Guarantees conformance to the stringent material and quality standards of the original aircraft Type Certificate. This ensures the part has the correct strength and fatigue life to perform its critical function reliably.

Aircraft Compatibility

The 1555014-2 is the specified OEM exhaust clamp half for thousands of the most popular Cessna aircraft ever produced. It is imperative to consult the specific aircraft's Illustrated Parts Catalog (IPC) for final verification of applicability and required locations.

• Primary Aircraft Models (Examples):
  • Cessna 172 Skyhawk (various models)
  • Cessna 177 Cardinal
  • Cessna 182 Skylane (various models)
  • Reims F172/F182

Applications

The 1555014-2 is a flight-critical component for maintaining the integrity of the exhaust system:

• Exhaust System Support: Provides the structural support necessary to prevent catastrophic failure of the exhaust tubes from vibration-induced metal fatigue.
• Mandatory Inspection Item: Exhaust clamps and supports are a key focus of every 100-hour and annual inspection. This component is replaced if any signs of cracking, corrosion, or deformation are found.
• Exhaust System Repair/Overhaul: New clamps are essential when replacing or repairing any component of the exhaust system to ensure it is properly supported.

Why Choose 1555014-2?

The failure of an exhaust clamp can lead to the rapid cracking of an exhaust riser at the cylinder flange. This can result in superheated exhaust gases blasting directly onto the firewall, engine accessories, or induction plumbing, creating a serious in-flight fire hazard and causing a loss of engine performance. Using a genuine Textron Aviation 1555014-2 OEM clamp is the only way to ensure the part has the correct material properties and a perfect fit to properly support the system. For a component this critical to safety, there is no substitute for factory-original parts.

An aircraft exhaust system is a dynamically resonant structure. The pulsating exhaust gas from each cylinder, combined with the engine's inherent vibration, can create harmonic frequencies that amplify stress at specific points in the system. The 1555014-2 clamp acts as a "node," a point of fixation that changes the natural vibrating frequency of the exhaust tubes. By rigidly clamping the tubes together, it dampens these harmful resonant vibrations and transfers the loads into support brackets rather than allowing them to concentrate at the most vulnerable points, such as the welds and flanges. The correct placement and torque of these clamps are therefore as important as the clamp itself for ensuring the long-term fatigue life of the entire exhaust system.

Note: This is a flight-critical component. It must be installed by a certified A&P mechanic in accordance with the current Textron Aviation maintenance manual. Always use two new clamp halves and the correct new hardware for each clamp assembly. Proper torque on the fastening hardware is critical for function.Alternate Part number:   0750161-25, A0750161-25
