0750161-25 - Textron Aviation Cessna OEM Exhaust Riser Half Clamp

0750161-25 – Textron Aviation Cessna OEM Exhaust Riser Half Clamp

Available now on the Airparts.aero Marketplace.

Overview

The Textron Aviation 0750161-25 is the genuine OEM, current-production riser half clamp, a flight-critical component for the exhaust systems on late-model Cessna 172 aircraft. This is one of two identical halves that, when bolted together, form a complete clamp assembly to rigidly secure the exhaust risers. Engineered from high-temperature, corrosion-resistant steel, this clamp is essential for supporting the exhaust system against the constant, high-frequency vibration of the engine. Proper support is the primary defense against stress cracks forming in the riser tubes, a potentially catastrophic failure. This part number is the direct superseding component for the older P/N 1555014-2.

Key Features

• Vibration Damping & Support: Its principal function is to provide a rigid support structure for the exhaust risers, preventing the destructive effects of engine vibration from fatiguing and cracking the exhaust tube welds and flanges.
• High-Temperature Stainless Steel: Fabricated from 321-grade corrosion-resistant steel (CRES) or a similar high-performance alloy. This material is chosen for its superior strength retention and resistance to cracking and corrosion at the extreme temperatures generated by the exhaust system.
• Precision Stamping: Each half clamp is precision stamped to the exact curvature and dimensions required by the latest engineering drawings, guaranteeing a perfect, secure fit around the exhaust riser tubes for uniform clamping force.
• Current Production Part: As the superseding part for P/N 1555014-2, this clamp represents the latest material and manufacturing specifications from Textron Aviation, ensuring the highest level of quality and reliability.
• Genuine Textron OEM Part: Guarantees conformance to the stringent standards of the original aircraft Type Certificate. Using the OEM part is critical for ensuring the safety and airworthiness of the exhaust system installation.

• Primary Aircraft Models:
  • Cessna 172R Skyhawk
  • Cessna 172S Skyhawk SP

Applications

The 0750161-25 is a flight-critical component essential for exhaust system integrity:

• Exhaust System Maintenance: A mandatory inspection item during every annual and 100-hour inspection. Clamps are inspected for cracks, security, and corrosion.
• Preventing Exhaust System Failures: Properly installed clamps are the primary defense against vibration-induced cracking of the exhaust riser tubes.
• Component Replacement: Replaced whenever found to be cracked, distorted, or heavily corroded, or when replacing associated exhaust components.

Why Choose 0750161-25?

A cracked or failed exhaust system component can lead to a dangerous in-flight fire, carbon monoxide contamination of the cabin, or damage to other firewall-forward components. The 0750161-25 clamp is an inexpensive but absolutely vital part of preventing such failures. Using a genuine Textron Aviation OEM part—and specifically the latest superseding part number—ensures that the clamp has the correct material alloy and is shaped correctly to provide a secure fit without creating stress points, reflecting the latest in engineering and safety standards.

The exhaust system of a reciprocating engine is subjected to a violent combination of thermal cycling and multi-axis vibration. The 0750161-25 half clamp is designed to be a rigid support node in this dynamic environment. By securely fastening the riser tubes, it effectively shortens the unsupported length of the tube, which dramatically increases its natural resonant frequency. This change in frequency moves it out of the range of the engine's primary vibrational frequencies, thereby preventing harmonic resonance—a phenomenon that can cause rapid and catastrophic fatigue cracking in the metal. The proper installation and torque of the hardware securing these clamp halves is therefore fundamental to the longevity of the entire exhaust system.

Note: This is a flight-critical component. Installation must be performed by a certified A&P mechanic. Two clamp halves (P/N 0750161-25) and new, specified hardware (bolts and nuts) are required to create one complete clamp assembly. Always inspect exhaust components for cracks and security in accordance with the aircraft's maintenance manual.FAA Eligibility [ Click Here ]

Product Overview

Riser clamp installation—the clamp is fastened to the structure. Riser clamps transfer the load of riser pipe to the building by interfacing with a structural member. Often, this is done by letting the riser clamp sit on the edges of a slab penetration. In effect, the hole in the slab acts as the hanger for the pipe.
