For long, flexible rotors operating above their first or second critical speeds, low-speed balancing is often insufficient. High-speed balancing inside a vacuum bunker allows technicians to observe modal deformation and place correction weights at specific axial planes, neutralizing dynamic deflections at full operating velocities.

For multi-stage centrifugal compressors or built-up turbine rotors, components like impellers, sleeves, and spacer rings are systematically unseated or thermally de-stacked. Heavy interference fits require precise induction heating or hydraulic pushing fixtures to avoid galling the shaft. 3. Non-Destructive Testing (NDT)

While the complete process is detailed in Chapter 1, Section 2, a typical rotor repair under API 687 includes:
