So I am rebuilding a Spacemaster and have it down to the bare frame. Got a good look at the winch and it looks a little rusty and rough. It is working fine, but I am wondering if there is any maintenance or care I can do to it to make it last a lot longer? Do any parts need lube or anything? I ordered new lift cables since the old ones have rusted and seized up turnbuckles, and have my fingers crossed I will be able to get the threaded hex screws out of the drum so I can replace the cables.
