As I was searching for equivalencies among sailboat winches I ran across this page of links to winch service manuals
. You'll be interested too because it has links to a couple dozen winches, including all the Barients on my Islander 30. It may have yours too. If you haven't taken your winches apart before, you'll find the exploded diagrams and instructions useful.
It also has a winch comparison table of which models of the different brands are close to the same specs, and a couple of the old catalogs.
5/6/2013 EDIT: Oh, for pete's sake. Sailnet.com mangled my post after I attached the link. I tested it as soon as it posted, and was originally fine. Here is the winch service site
. (It is http://l-36.com/winches.php
for your reference in case it gets mangled again).
