I can't speak to your RS rotator specifically, but I would suggest when you open it, have it over a big tub or bucket. I opened a Wilson rotor many years ago and became instantly familiar with the ball bearings when some stuck to the top and some stayed in the bottom raceway. Most of the rest jumped out all over the floor.

Good luck. Jim

I sometimes use for some satellite work. But the rotator is need of some clearing and lubrication. Has anyone taken one of these apart and can share some insight as to what I might expect to find once I remove the motor and gear assembly from it's housing. I assume the 4 large bolts inside the bottom cover where you would attach the wires are holding the motor assembly in place. Are there any ball bearings that I might expect to come rolling out if I disassemble it? I looked for a You Tube video for some help but came up empty. Figured the next best place to ask would be with other satellite operators.
