I greatly appreciate the responses to my question.
The problem was in dismantling the motor. I had tried opening the motor before using a wide-bladed screwdriver in the gap between the two ends, to force the two black ends apart, but fearing damage, I stopped using that method.
I viewed the video on You-tube, and it was perfect! I'll try that immediately.
The motor has been screeching on and off for the past few years, but lately has become intolerable. There may be permanent damage to the bearing. I'll know when I get the motor disassembled.
I plan to transfer all my old LPs and 45's that are not available on iTunes or Amazon using this turntable (I bought it new many years ago), but the noise was being conducted into the recording as a low rumble.
Again, many thanks to all!
