[67C10Step]

Guess I should have clarified. This thing is old. Guessing probably 1950's or 1960's and the motor is just as old. If it had the typical single or double sealed ball bearings like newer stuff I'd already have it apart.

This motor appears to have lubricated sleeve bearings. See photo. I have ordered some 20wt oil for electric motors and will try that first. Could be the old belt on it making a ton of noise as well. Doesn't seem to be loose in the radial direction but the shaft will move up/down about 1/8 of an inch.
