Beogram 4002 DC Motor Restoration

A Beogram 4002 DC platter motor recently arrived from Florida for restoration. It emitted the usual shrieking noises when I ran it from my bench supply. A clear indication that the bearings were dry. This shows the motor as received:

I took the motor apart to extract the bearings (on the black pad):

Then it was time to immerse them in motor oil and pull a vacuum:

Immediately, vigorous bubbling started indicative of air being drawn from the pores of the Oilite bearing material to make room for oil. After about 2 days the bubbling stopped after the oil was replenished in the bearing. I extracted the bearings:

And then it was time to reassemble the motor. I installed it in one of my Beogram 4002s and ran a 24 hrs stability test with my BeoloverRPM device:

The BeoloverRPM can log the RPM over extended periods of time. This is the RPM curve I measured for this motor:

This is as good as it gets for 4002 DC platter motors, i.e. this motor is ready for duty again.
