Recently acquired am fr-3060 in a package deal with some other gear. Had a new belt included and was told we couldn’t test because no belt was on it, so bought as-is. I took platter off and tried spinning the brass spindle that the belt goes on and could barely turn it. I took it off via set-screw. I then took the two screws out to loosen motor and turned unit upside down to access whole motor. I tried to oil a couple areas to get motor turning and nothing broke loose. Has anyone had this problem or know the fix? It’s too cool of unit to let go.
