5.4.15 Low-stage Rotors and Main Rotor Casing

Care must be taken because the low-stage rotors are heavy.
In addition, since the low-stage M rotor is installed with a mechanical seal; do the work very carefully
not to damage the shaft. It is recommended to apply a protective tape on the shaft surface.
Inspect the ends of the rotor lobes and main rotor casing in the same way as the high-stage, but be
aware that there is an unloader slide valve on the low-stage which may hit against the ends of the rotor
lobes. If the contact is particularly hard, scrape off the contacting parts with a scraper or file. Finally,
make the surface smooth with sandpaper. After making the surface smooth, wash thoroughly with wash
oil and make sure that no iron powder is left inside.
