Overview
The 956A6990G01 is a high-performance, master-grade Accessory Gearbox (AGB) Rotary Shaft Seal Installation and Removal Tool Kit custom-engineered for the rigorous maintenance, modular repair, and overhaul (MRO) of CFM International LEAP series turbofan engines. Classified as a flight-critical propulsion Ground Support Equipment (GSE) tooling asset, this specialized kit is purpose-built to facilitate the absolute, micro-tolerance extraction and seated pressing of rotary carbon/elastomeric fluid seals across the AGB drive shafts No.3, No.5, No.7, and No.8. Manufactured by JUNXUN to comply with strict CFM LEAP engine shop manual parameters, the 956A6990G01 incorporates a linear force-distribution alignment geometry that enables workshop technicians to complete rapid seal swaps without causing dynamic axle journal scoring, casing thread stripping, or localized oil-weeping seal lip distortion.

Key Points
Multi-Station Shaft Adaptability: Comprehensive master kit equipped with dedicated index sleeves and puller jaws custom-profiled to fit the exact geometric diameters and spacing of LEAP AGB shafts 3, 5, 7, and 8.

Linear Anti-Distortion Compression: Features a precision-guided mechanical lead screw and mandrels that deliver perfectly axial, orthogonal force during seal installation, eliminating seal tilting or lip rollover.

Heavy-Duty Aerospace Tooling Metallurgy: Fabricated from premium, heat-treated high-tensile chrome-moly steel and passivated structural alloys to ensure high torque resistance and prevent tool thread galling.

Non-Marring Shaft Contact Shields: Outfitted with specialized protective guide pilots and soft-faced backing adapters that isolate high extraction forces away from the high-precision polished shaft shoulders.

Applications
CFM LEAP Propulsion AGB Modular MRO: Deployed by certified aero-engine technicians within heavy repair bays to replace worn dynamic seals during scheduled engine shop visits or quick-turn module repairs.

Flight Line Flight Line Leakage Remediation: Utilized as a rapid-deployment tool kit by airline line maintenance crews to rectify oil weeping from accessory drive ports directly on the wing.

Airlines Engine Tool Crib Fleet Supply: Essential specialized tooling inventory for global commercial airlines operating A320neo, B737 MAX, and C919 fleets to minimize hangar turnaround times (TAT) and ensure dispatch safety.
