Overview
The 856A3409 is a high-precision Guide Pins Kit (KIT PINS GUIDE) specifically engineered for the maintenance, disassembly, and reassembly of CFM56 series engines. Fully compatible with CFM International specifications and Rhinestahl CTS engine tooling systems, this essential aerospace MRO hardware kit is designed to guide heavy internal engine modules during mating operations. By ensuring flawless geometric alignment and concentricity, the 856A3409 prevents critical components from clashing, scratching, or binding, safeguarding expensive airframe and propulsion assets during overhaul workflows.

Key Points
CFM56 and Rhinestahl CTS Compatibility: Custom-machined to integrate seamlessly with both standard CFM56 engines and Rhinestahl CTS maintenance shop equipment profiles.

Precise Coaxial Alignment: Engineered with micro-tolerances to guide complex internal modules smoothly into place, eliminating manual positioning errors and structural friction.

High-Tensile Mechanical Strength: Manufactured from premium, heat-treated alloy steel capable of supporting massive sheer and weight forces during heavy module extraction or insertion.

Non-Destructive Lead-In Design: Features optimized tapered tips and micro-polished surface finishes to allow effortless engagement and smooth insertion into structural guide holes without galling.

Applications
CFM56 Engine Module Assembly: Deployed in MRO facilities to guide major engine core modules (such as fan, compressor, or turbine sections) into position during rebuild stages.

Rhinestahl CTS Tooling Interfaces: Used as a direct replacement or supplementary guide pin set in specialized Rhinestahl engine transport cradles and assembly fixtures.

Propulsion Repair and Quality Control: Utilized by airline engineering hubs and engine overhaul shops to streamline shop visit workflows and minimize component damage risks during handling.
