Overview
The 856A3924G01 is a high-performance, precision-engineered Bushing Reengagement Tool custom-designed for the rigorous assembly, rigging, and overhaul (MRO) of CFM56 series turbofan engines. Classified as a flight-critical powerplant handling asset and specialized Ground Support Equipment (GSE), this mechanical alignment tool is purpose-built to facilitate the safe and controlled re-mating of critical accessory drive shaft bushings and transmission splines. Manufactured by JUNXUN to comply with strict CFM International engine shop manual specifications, the 856A3924G01 provides an absolute, rigid mechanical guide that ensures perfectly synchronized tooth-in-slot engagement, preventing devastating spline wear, axial misalignments, or housing-interface damage during high-load accessory gearbox servicing.

Key Points
Dedicated CFM56 Spline Integration: Custom-machined to align seamlessly with the standardized indexing patterns of drive shaft bushings proprietary to the CFM56 accessory gearbox module.

Controlled Force-Engagement Architecture: Features a precision-threaded or slide-guide mechanism that allows hangar technicians to apply steady, orthoganal linear pressure, eliminating the risk of sudden spline binding.

Aero-Grade Heavy-Duty Metallurgy: Fabricated from premium, heat-treated high-tensile alloy steel certified to withstand intensive mechanical usage cycles without thread stripping or structural deflection.

Non-Marring Precision Mating Surfaces: Outfitted with passivated contact shoulders that protect high-value, mirror-finished transmission surfaces from metal-on-metal scratching and debris-induced scoring.

Applications
AGB Accessory Drive Module Overhaul: Deployed by certified aero-engine technicians during the installation of overhauled fuel pumps, hydraulic pumps, or starter units to ensure clean, damage-free re-mating.

Line Maintenance Gearbox Integrity Audits: Utilized within specialized repair cells to safely verify or re-seat spline-bushing connections during unscheduled field troubleshooting.

Airlines Fleet Tool Crib Logistics: Essential specialized GSE hardware for global airlines, regional cargo operators, and third-party MRO facilities servicing the A320 and B737 classic/NG fleets to minimize unscheduled engine removal (UER) events.

856A3924G01 is a precision structural and hydraulic interface component for aviation maintenance tools and ground support equipment, compatible with global narrow-body, wide-body and regional commercial aircraft fleets. Manufactured in strict compliance with AS9100D aerospace quality standards and FAA/EASA safety specifications, it is precision-machined from high-strength, corrosion-resistant aerospace-grade alloy with a hardened, anti-wear and anti-fatigue surface treatment. Engineered to endure harsh airfield conditions including continuous vibration, mechanical shock, extreme temperature fluctuations, and exposure to hydraulic fluid, jet fuel and deicing chemicals, it features ultra-tight dimensional tolerances and industry-standard mounting and fluid ports for direct drop-in integration. It improves system rigidity, sealing reliability and operational stability, effectively extending service life and ensuring safe, consistent performance in worldwide aircraft MRO operations.
