Any tips on replacing those rubber motor mount insulators used on the early Edison Standards? I am referring to the ones that were later replaced with spring shock absorbers. I was wondering about RTV or pure silicone? Any advice will be greatly appreciated.
Thanks!

Ron Sitko has all of the rubber parts for these and sells them as a kit - enough for 1 machine.

Ron Sitko does have those supplies. I had replaced some onetime with sorbothane, it is expensive, but works excellent, keep oil away from it, it effects it.

Can anyone please explain how to safely remove the screws to replace those rubber insulators? They have some kind of round clip on top instead of a nut and I was afraid to break or scratch anything when using too much force.
Thanks

Thanks for the tip, they are on order.
Andreas: I just used a screwdriver and they came right out. There was not much holding the weird round nut anymore. Perhaps you need some vice grips to hold that round nut.

If the nuts are stubborn some heat does wonders to get them off.

I literally spent hours trying to screw, push, rip, pry these things off to no avail. They just turn around forever and don't come off. So these are literally supposed to be nuts with a thread inside? If so then those on my Standard have lost that thread long time ago. They behave more like a two part rivet. I'll have to try heat when I have time to work on it again.

I have used either Kroil, PB Blaster, or Liquid Wrench. They work great, too. They won't mar the bed plate.

Once you use any of penetrating oils, use a very small vice grips to lock the nut. To protect the nut, use a small rubber square on each jaw of the vice grips.

Thanks for the suggestions, but I already tried penetrating oil. It's not that the nuts don't move, in fact they probably move too freely. Maybe the threads are shot completely? I'll probably order replacements to see and understand how they should work and why they don't come apart.

Thanks again
