Center Vent Tube Locating Plug for Aircraft Maintenance
Overview
The 856A3101G02 is a high-precision Center Vent Tube Locating Plug specifically engineered for the CFM56 engine series. This essential piece of Ground Support Equipment (GSE) is designed to ensure the exact alignment of the center vent tube assembly during critical engine build-up and testing phases. Beyond its indexing function, the 856A3101G02 acts as a protective barrier, preventing environmental contaminants from entering the engine’s internal ventilation pathways during maintenance or inspection procedures.

Key Points
Precise Indexing & Alignment: Custom-engineered to provide a perfect fit within the center vent tube, facilitating the accurate positioning of internal engine components.

Dual-Function Design: Serves both as a spatial locating tool for assembly and as a protective plug to maintain internal cleanliness and prevent FOD (Foreign Object Damage).

Aerospace-Grade Durability: Manufactured from high-strength, dimensionally stable materials to ensure the plug maintains its precise tolerances over repeated use in rigorous MRO environments.

Easy Installation & Removal: Features an ergonomic interface designed for quick deployment by technicians, streamlining the engine assembly and testing workflow.

Application
Engine Assembly & Overhaul: Used to align the center vent tube when mating major engine modules or during the reinstallation of core components.

Pressure & Flow Testing: Provides a secure seal for the ventilation system during specialized diagnostic checks and performance validation.

Storage & Transport: Protects the vent tube interface from debris and moisture while the engine is off-wing or being prepared for shipment.
