Overview
The 856A3746G03 is a high-performance, heavy-duty Radial Drive Shaft Installation and Removal Tool custom-engineered for the rigorous maintenance, structural overhaul, and module-level rigging of CFM56 turbofan engines. Classified as a flight-critical powerplant handling asset and specialized Ground Support Equipment (GSE), this specialized rigging tool is purpose-built to facilitate the safe extraction and precise re-mating of the engine’s radial drive shaft within the transmission gearbox housing. Manufactured by JUNXUN to comply with strict CFM International engine shop manual dimensions, the 856A3746G03 establishes an absolute mechanical guide that prevents damaging spline binding, rotational misalignment, or housing-interior scarring, ensuring reliable power transmission between the engine core and accessory gearbox modules post-maintenance.

Key Points
Dedicated CFM56 Radial Shaft Fitment: Custom-machined to interlock seamlessly with the specific drive shaft geometries, locking collars, and spline patterns proprietary to CFM56 series engines.

Controlled Linear Force-Distribution: Features an optimized puller/pusher mandrel architecture that ensures steady, balanced axial movement, effectively eliminating the risk of spline-tooth impact or shaft canting.

Aerospace Metallurgy Integrity: Fabricated from premium, heat-treated high-tensile alloy steel certified to withstand intensive mechanical loads without thread stripping, tooth deformation, or structural fatigue.

Non-Marring Precision Contact Faces: Outfitted with passivated contact shoulders and protective guide pilots that shield high-value, polished transmission surfaces from metal-on-metal friction and debris-induced scoring.

Applications
AGB Accessory Drive Module Overhaul: Deployed by certified aero-engine technicians during scheduled C-checks and D-checks to remove and install the radial drive shaft while performing gear-train inspections.

Engine Field Drive Line Troubleshooting: Utilized within specialized maintenance bays to safely troubleshoot vibration or noise issues stemming from the radial drive line without needing a complete engine teardown.

Airlines Fleet Tool Crib Logistics: Essential specialized GSE hardware for commercial airlines, regional fleet operators, and third-party MRO facilities to complete rapid CFM56 engine turnaround times (TAT) and ensure airworthiness.

856A3746G03 is a precision-engineered core interface component dedicated to 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, wear-resistant and anti-fatigue surface treatment. Engineered to endure harsh airfield environments including continuous vibration, mechanical impact, extreme temperature fluctuations and exposure to hydraulic fluid, jet fuel and deicing agents, it features ultra-tight dimensional tolerances and industry-standard mounting interfaces for direct drop-in integration. It significantly enhances structural rigidity, connection stability and operational safety of GSE and maintenance rigs, extending service life and ensuring consistent, reliable performance in worldwide aircraft MRO operations.
