Overview
The 856A3925G01 is a high-performance, master-grade Bushing Puller and Extraction Tool custom-engineered for the rigorous maintenance, modular repair, and overhaul (MRO) of CFM56 series turbofan engines. Classified as a flight-critical powerplant handling asset and specialized Ground Support Equipment (GSE), this tool is purpose-built to facilitate the controlled, non-destructive extraction of interference-fit bushings from the engine accessory gearbox (AGB) and transmission housing. Manufactured by JUNXUN to comply with strict CFM International maintenance manual specifications, the 856A3925G01 ensures a perfectly axial pull, preventing housing bore scoring, thread stripping, or localized metal fatigue during high-tension removal sequences.

Key Points
Precision-Expanding Puller Jaws: Engineered with a micro-tolerance internal expanding mechanism that ensures a secure, positive-locking grip on the interior of the bushing, preventing slippage during high-force extraction.

Axial Load-Distribution Lead Screw: Features a refined mechanical lead screw architecture that provides smooth, steady extraction force, effectively eliminating the risk of sudden, jarring movements that cause housing damage.

Aerospace-Grade Tensile Alloy: Fabricated from premium, heat-treated high-tensile chrome-moly steel to withstand intensive duty cycles without structural deformation or thread wear.

Non-Marring Guide Pilots: Outfitted with specialized protective guide pilots and passivated contact surfaces that protect the highly polished, precision-machined housing bores from metal-on-metal friction.

Applications
CFM56 Accessory Gearbox (AGB) Overhaul: Deployed by certified engine technicians during shop visits to safely remove seized or worn drive-shaft bushings prior to module rebuilds.

Propulsion System Maintenance Repairs: Utilized within specialized repair cells for rapid, damage-free bushing replacement, ensuring compliance with engine overhaul specifications.

Airlines Engine Tool Crib Logistics: Essential specialized GSE hardware for international airlines, regional fleet operators, and third-party MRO facilities servicing CFM56 engines to minimize hangar turnaround times (TAT).

856A3925G01 is a precision-engineered core component for critical aviation ground support equipment (GSE) and professional aircraft maintenance rig systems, compatible with global mainstream commercial narrow-body, wide-body and regional aircraft fleets. Manufactured in strict compliance with AS9100D aerospace quality standards and FAA/EASA safety protocols, it is precision-machined from high-strength corrosion-resistant aerospace-grade alloy with a rugged wear-proof and anti-fatigue surface finish, optimized to endure harsh airfield operational conditions including heavy structural load, continuous vibration, mechanical impact and extreme temperature fluctuations. It delivers exceptional structural resilience and long-term durability, featuring ultra-tight dimensional tolerances and industry-standard mounting interfaces for seamless integration into GSE and maintenance assemblies, effectively enhancing the structural stability, operational reliability and service life of ground support equipment for worldwide aircraft MRO and on-tarmac ground support operations.
