Before taking the winch apart...
take a box taller than the winch and cut a round hole in the bottom the same size as the base of the winch. Place this over the winch and any part that might drop or fly off,..i.e., springs, pawls, retaining ring, will have a much better chance of falling into the box instead of in the drink. As you lift the drum off, there should be a set of pawls attached to the inside of the drum. Make note of how these are set before taking them off and cleaning them. You should be able to buy a repair kit for your particular winches if any of the springs or other small parts are worn or broken. Usually, the springs are the first to go. You should be able to locate a manual showing an exploded view of the inside of the winch. This is most helpful and takes some of the anxiety out of opening that contraption for the first time. If you're really nervous about opening it on the boat, you can always unbolt it, take it home and spread it out on the dining room table.Good luck,RolandSV Fraulein IITarpon Springs, Fl.
