After 5 days, we seem no closer to getting this winch apart. All the appropriate screws are out. PB Blaster, Liquid Wrench, WD-40, CLR, Corrosion Block and hot water, all to no avail. We have probably cleaned out 75% of the corrosion (using knives, dental tools and putty knives), but still no movement at all. We just can not remove any more of the corrosion.
Also tried beating on the bronze (not shaft, base) with a hammer, putting it under extreme pressure by winching, in several directions. Lewmar suggested beating with hammer (and wood) sideways on the top of the spindle (where line is in pic 4), but that didn't do anything either. Obviously, heat won't work as irreplaceable bearings have plastic bits and it's mounted on wood.
It's taken Lewmar, Winch Spares and Mallorca Yacht Service several weeks to identify the winch and to find the appropriate diagrams and plans. They've all done a fine job. Tried all their suggestions, too.
All we're trying to do is get them apart for servicing, but no joy.
Picture 5 shows groove, see yellow arrows. Picture 4 shows sideways pressure. Picture 2 shows putty knife in groove. Picture 8 shows the same corrosion that cracked another winch base, since repaired with epoxy and painted, but we'll deal with that another day.
Thanks for any ideas.
