Over the weekend I noticed that my winch is leaking green grease. The grease must be breaking down. I think that these are most likely the original winches (1972). They are bronze. Time for some maintenance. I seem to remember reading just recently about how to do this task. I can't remember where, but I will do a little research. Is this a difficult job? Any tips or traps that I should be aware of before starting? Thanks, Kevin.
