Engine maintenance tool 856A1869G0

The 856A1869G01 Push/Pull Fixture is a highly specialized engine shop tool engineered exclusively for the CFM56 engine family. It is designed to safely and efficiently handle the High Pressure Turbine (HPT) rotor aft blade retainers. By utilizing a controlled push-pull mechanical action, this fixture allows MRO technicians to extract or seat these critical retaining components with absolute precision during hot-section teardowns or rebuilds. Precision & Safety in Hot Section Maintenance The High Pressure Turbine operates under extreme centrifugal forces and temperatures, meaning all components, especially blade retainers, are manufactured to exceptionally tight tolerances. Attempting to remove or install these retainers with generic tools can result in uneven pressure, leading to galling, distortion, or costly damage to the turbine disk lugs and blade dovetails. The 856A1869G01 fixture eliminates these risks by applying a smooth, purely axial push-pull force. This ensures the retainers slide into or out of position flawlessly, protecting the most valuable assets of the CFM56 engine. Key Features & Benefits • Dedicated CFM56 Geometry: Custom-profiled to match the exact dimensions of the CFM56 HPT rotor aft blade retainers, ensuring a secure and non-marring fit. • Controlled Axial Force: The advanced push-pull mechanism eliminates the need for impact tools, drastically reducing the risk of component micro-fractures. • Protects High-Value Parts: Safeguards expensive turbine blades, disks, and the retainers themselves from accidental mechanical damage during overhaul.
