The reason behind trying to salvage this motor is the shaft length and diameter. Not an easy combination to find. Also this is for a "M-D" or M drill with a taller belt housing for more pulley steps and a longer shaft than my other M head. Looks like it's never been abused other than zero indication it was ever lubed.
My other M Head is off the mill because the metric to SAE key I made for the metric shaft 3Ph motor with the longest shaft I could find at the time isn't tight enough and it is walking out of the key way despite the set/grub screw. Chicken or the egg . . .
The M-D motor will spin up without a load. Nothing with a load.
Capacitor has no markings. Tried a 50 micro farad 370/440, sat and hummed.
Removed motor (cast iron frame, at 66 this is getting old) and disassembled to check centrifugal clutch. Clutch appears to be fine, contacts closed have continuity through the points and starter winding. Point open fine and break the circuit. Starter field doesn't present being grounded.
Ideas?
TIA
