I was given an old, rusty and very dirty manual hoist similar to the following
which was "stuck" (would only go up). After taking it apart and rigorously cleaning the pieces, the issue is solved.
Now that I have to put it back together, which part(s) in addition to the bearing should I lubricate? In particular, should I use lubricant on the gears? What about the chain? What kind of lubricant should I use?
I am afraid that lubricant is going to keep dirt in the mechanism which I would prefer to avoid if not necessary.
