98N7830H002-001 is a precision-machined aerospace engine turbine disk alignment gauge, compliant with AS9100D quality standards and FAA/EASA MRO regulations, designed for CFM56 and IAE V2500 turbofan engines. It is used to measure and verify the coaxiality of turbine disk assemblies during maintenance, ensuring that the disk, blade, and shaft components maintain precise alignment, which avoids excessive vibration, uneven wear, or structural damage during high-speed engine operation.

Constructed from high-strength stainless steel with a corrosion-resistant finish, it features a precision-calibrated measurement surface, operating stably in -20°C to 70°C workshop environments. Weighing 0.52kg with an ergonomic grip and clear measurement scales, it streamlines alignment inspection workflows and ensures measurement accuracy within 0.02mm. It is an essential tool for turbine system MRO work.
