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).
