"1) Remove the rotor from the coil assembly. You can probably push it out, or loosen the screws on either side of the coil to help free it.
2) Place (balance) the rotor, pinion gear side up, on top of a light bulb (60 to 100W) and try to get the rotor as level as possible.
3) Turn on the light and let the rotor cook for at least 30 minutes. When time is up, shut off the lamp, leave rotor in place, and apply a drop or two of oil onto the pinion gear. You should see it fill the small well around the gear's base, and then slowly (or sometimes quickly) be absorbed into the rotor case. Repeat this until you've added 15 - 20 drops of oil. If it stops drawing it in, heat the rotor up again and then pick up where you left off.
4) Install the rotor back into the coil assembly, connect to power, being careful not to disturb the soldered connections on the coil. Check gear for rotation. Information on the rotor case should indicate the rotor runs at 3.6 RPM. I sort of eyeball it and check against a clock with a sweep second hand.
If the rotor is noisy, you may want to heat it up once more and add maybe 5 or 10 more drops of oil. Less is more. Too much oil and it will bog down the mechanism inside the rotor and cause it to run too slow. Noisy rotors that have been revived can sometimes quiet down once they're back in use for a while too. "
