My recently acquired, flea-market RX 2, has a noisy, "chattery" motor. They seem to be few and far between on the 'net. The only one I found, on eBay, was sold. So, I'm thinking, its already bad. What do I have to lose if I tear it apart? So, I carefully strip it down to parade rest. Each and every part, (including the tiny brushes), layed out in front of me. I clean and Deoxit the brushes and commutator. Lightly grease the bearings. And I see the problem. The little plastic ring that holds the FG servo magnet in place has delaminated and is "splintering" off to the sides. I carefully superglue and hold them back into alignment. Then I put it all back together. (I noted the wiring color codes on a 3x5 card before disassembly.)
Put her back into the table and she purrs like a silent kitten . . . . . . backwards! 😡
The thing that's driving me nuts here, is that you can't reverse the polarity of the assembly. The circuit board only fits onto the motor one direction because of the slot for the 8-pin DIP dual Hall-effect quadrature IC for the FG circuit. I can't put the motor cover on backwards.
But its late, and I'm going to bed. If I figure out what I did wrong, I'll post tomorrow. I'm sure its something I did. Or the BeoGod hates me.
