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.
