Overview

The 856A3100G05 is a critical Locating Center Vent Tube tool specifically designed for the CFM56 engine maintenance and inspection cycle. This precision-engineered GSE component is indispensable for establishing the correct spatial orientation and axial alignment of the engine's internal venting system. By ensuring the center vent tube is perfectly positioned during module mating or core assembly, the 856A3100G05 prevents costly misalignment errors and ensures the long-term reliability of the engine’s thermal management and lubrication pathways.

Key Points

Axial Alignment Precision: Specifically calibrated to align the center vent tube with the internal bearing chambers and sumps, ensuring a seamless interface between modules.

Critical Reassembly Support: Facilitates the safe and accurate insertion of the vent tube assembly, reducing the risk of 'binding' or seal damage during the build-up process.

High-Stability Construction: Manufactured from aerospace-grade alloy steel with high dimensional stability to maintain strict tolerances under hangar and workshop conditions.

Corrosion-Resistant Finish: Treated with a specialized industrial coating to resist aviation fluids and oils, ensuring the tool's longevity in professional MRO environments.

Application

Major Engine Overhaul: A mandatory tool for technicians during the reassembly of the CFM56 core modules where center vent tube positioning is paramount.

Module Mating Procedures: Used as a mechanical guide to ensure concentricity between rotating and stationary internal components.

Professional Repair Shops: An essential inventory item for facilities performing C-Checks and D-Checks on Boeing 737 and Airbus A320 powerplants.
