I got a screamin' good deal on this Ham M rotator, after persistent winds damaged the TV antenna rotator I originally used with my Moxon. Upon testing it out, I found out it worked! Opening it, everything looked in great condition, so all I was re-grease the bearings with white lithium grease and clean the azimuth potentiometer with contact cleaner.

Upon receipt.

I figured out my bike repair stand works well for supporting the rotator under repair.

Bearings and case opened up.

Cleaning the bearings and rig gear with WD-40.

The motor, brake relay, and drive gears all look great!

Reassembly.
