out, and/or wear the graphite quickly. First, visually inspect the rotor for surface finish, nicks,
or scrapes. If it appears in good shape it should be tested. Run a new vane through each
slot by hand. It should slide freely through each slot. Assemble the rotor with the vanes,
pins(if applicable), liner, and flanges. The rotor should spin smoothly and easily by hand. If it
feels like its scraping the graphite, or if it becomes particularly difficult to turn through part of
the revolution, the problem needs to be addressed before proceeding. Separate the rotor
from the graphite and look for scrape marks as an indication of where the problem lies.
Sometimes the rotor can be salvaged if it’s just a very small nick or galled particle causing the
issue. Try carefully using a file to smooth the area causing the problem. Retest the rotor in
the graphite. If it seems smooth, proceed to the next step.
