I disassembled the turret, cleaned and relubricated the worm gear assembly and the needle bearings. I did note uneven wear on the transmission ring gear, but nothing that would worry me if i saw it anywhere else. After reassembly and adjustment, the turret seems to move smoother and more quietly, howener as soon as we loaded tools, the problem came right back.
Next step is to take the motor and send it to a rebuilder for testing.
