Overview
The 856A3272G01 is a mission-critical N°4 Bearing Front Rotating Oil Seal Puller specifically designed for the CFM56 engine maintenance program. This specialized extraction tool is engineered to facilitate the safe removal of the rotating oil seal located at the front of the N°4 bearing station. By providing a controlled and uniform pulling force, the 856A3272G01 allows technicians to perform sensitive disassembly tasks without risking damage to the precision-machined shaft surfaces or the bearing housing.

Key Points
N°4 Station Specificity: Custom-contoured to interface perfectly with the geometry of the CFM56 N°4 bearing seal, ensuring a secure grip and optimal mechanical leverage.

Damage-Free Extraction: Engineered to eliminate the risk of marring, scratching, or deforming the rotating seal and surrounding hardware during the removal process.

Precision Threaded Mechanism: Features high-grade threaded components for smooth, incremental force application, allowing for steady and safe seal extraction.

Heavy-Duty Aerospace Build: Manufactured from premium, heat-treated alloy steel with an anti-corrosive finish to ensure longevity in high-cycle MRO (Maintenance, Repair, and Overhaul) environments.

Application
Bearing Seal Replacement: The primary tool used during the inspection or replacement of the front oil seal in the N°4 bearing chamber.

Engine Core Maintenance: Essential for technicians performing deep-level repairs on the engine’s hot section and rotating assemblies.

Aviation Workshop Efficiency: Minimizes downtime by providing a reliable, standardized solution for one of the more delicate disassembly steps in the CFM56 maintenance manual.
