so i did a search and couldn't find an answer. what should you do to tune up an old winch that is working but brand new to you? I just bought a used warn m10,000. Before I mount it I would like to do any appropriate maintenance. the cable is great and was properly laid. it was mounted on a truck with no cover so the powdercoat is good but the drum has surface rust and the bottom of the power box and straps holding the motor have surface rust. otherwise it looks pretty good. I am thinking clean up the rust as best I can and paint what was rusty, put dieletric grease on all the connectors and maybe a change of the gear oil. what kind of oil do these puppies use? Is there anything else needed?
