Overview

The 856A1099G01 is a high-precision HPT Aft Outer Seal Fixture (FIXT HPT AFT OUTER SEAL) custom-engineered for the maintenance, repair, and overhaul of CFM56 series aircraft engines. This specialized aerospace tooling fixture is purpose-built to hold, support, and secure the High Pressure Turbine (HPT) aft outer seal assembly during critical engine teardown and rebuilding sequences. Manufactured by JUNXUN to meet strict aviation OEM engineering tolerances, the 856A1099G01 ensures flawless geometric alignment and prevents component distortion during installation and removal, directly protecting the turbine module's pressure integrity and operational safety.

Key Points

Dedicated CFM56 Engineering: Tailored precisely to match the dimensional layout and structural attachment criteria of the CFM56 high-pressure turbine section, preventing component clashing.

Distortion-Free Fixing Mechanism: Provides rigid, uniform clamping and support across the circumferences of the aft outer seal, eliminating mechanical stress or warping during installation workflows.

Heavy-Duty Workshop Construction: Fabricated from high-tensile, industrial-grade alloys capable of enduring continuous chemical exposure and mechanical forces within aggressive engine hangar environments.

Streamlined Maintenance Efficiency: Optimizes shop visit turnaround time (TAT) by allowing technicians to position and lock critical hot-section seals quickly and with repeatable mechanical accuracy.

Applications

CFM56 High Pressure Turbine Overhaul: Essential turbine cell tooling utilized by certified engine MRO stations during the disassembly, inspection, and rebuilding of HPT modules.

Aviation Seal Replacement & Repair: Deployed by powerplant mechanics to facilitate the seamless extraction of worn aft outer seals and the highly accurate seating of replacement components.

Propulsion Quality Control and Assembly: Utilized as a certified reference holding fixture to maintain standardized OEM quality tolerances prior to the final assembly sign-off of the turbine stack.
