Hi Chuck, I went out and took everything apart on the crane, I tapped in the bushing that the motor shaft rides threw so that took out the slop between that and the brushes. Lubed it all up did a test run with just the motor and its nice and quite now. Then I did a test with all the gears in place and still nice and quite. Now I have to add the solenoids hooked back up and give it another test run.
Then last but not least hook up the control panel!
Thanks for all your help!
