Micro Seiki RY-5500 motor noise repair pdf

I recently acquired a wonderful turntable, the Micro Seiki RX-5000. I found there is scant information available on the Internet about this vintage 'table, and when I encountered some noise issues with my RY-5500 motor unit and discovered how to fix it, I thought it would be beneficial make a set of instructions freely available. Go to the following URL and click on the page icon to view and download these instructions. Enjoy!

feet on the motor base are solid solid brass pins and seem to me to have no isolating properties at all. Has anybodyt replaced theirs or do they resort to the above isolation measures.

I did a few experiments with the RY-5500 motor
I used Sorbothane feet below it, but the Bass Performance was gone. Same with springs.
It is the result, that the Motor is nor REALLY stable, a touch of movement which was reflected via Belt to the Platter.There was a change in the Performance, but not to the better. I always went back to stock feet.
I use a Vibraplane below both units. The result is stunning.

I was lucky enough to find a Micro Seiki HS-80 High Inertia Unit flywheel

Are there more? :)
