98V20003003000 is a specialized aerospace engine compressor rotor alignment tool, compliant with AS9100D quality standards and FAA/EASA MRO regulations, designed for CFM56 and IAE V2500 turbofan engines. It is used to measure and adjust the coaxiality of compressor rotor assemblies during maintenance, ensuring that the high-pressure and low-pressure compressor rotors maintain precise alignment with the engine shaft, which avoids excessive vibration, uneven component wear, and reduced compression efficiency during engine operation.

Made from high-strength alloy steel with a corrosion-resistant coating, it features precision-calibrated measurement references, operating stably in -20°C to 75°C workshop environments. Weighing 0.98kg with an adjustable positioning structure, it streamlines alignment adjustment workflows and ensures alignment accuracy within 0.03mm. It is an essential tool for compressor system MRO work.
