Cleaning & lubing a winch is not complicated but can get tedious, especially if doing it on-board. This old Lewmar "England" style winch is built like a tank but suffers from a design issue which necessitates removal from the boat for a proper clean and lube. Many newer winches are designed so the base can be left attached and a proper cleaning can be effected, this one was not.

If your winch was bedded with 3M 5200/Satan Glue, well, sorry for that, and good luck removing it. This starts with the winch already removed from the boat.

First things first the black top, which also serves as the line stripper, needs to be removed. A simple tap with a plastic hammer, seen in the back ground, in a counter clockwise direction, will have it spinning free in no time.
