Has anyone come across this type of winch? My boat has one - 2 speed chrome. I'd like to service it but havent worked out how it comes apart. There are 2 small holes in the top either side of the hole to insert handle and and another with a very small allen bot (2mm or so). Removing the allen bolt has no effect. Looks like I might need a special tool to fit across the 2 holes. Similar to a pin spanner used for angle grinders. Anyone with any ideas?
