Anchor windlass disassembly

hi,
I have a lewmar (simpson/Lawrence) anchor windlass. I have found that it is leaking when it rains and have been attempting to disassemble it w/o any luck so far. I have taken the nuts off of the 4 bolts that come from the base plate through the deck. I have knocked the windlass w/ a hammer from above and below deck to loosen, but there appears to be a rather large 8 sided metal rod that extends from below up to the gypsy. any suggestion on the correct method for releasing this?
cheers,
keith

Re: anchor windlass disassembly

Lewmar makes a lot of different windlasses, some of which are horizontal, some of which are vertical.

You'll get better advice by giving us a hint as to which model you're hoping to disassemble.

Re: anchor windlass disassembly

What model S-L windlass.

From your description of actions you've taken so far I think you are trying to remove the windlass from the deck of the boat and not disassemble the windlass itself?

My S-L Seawolf 520 is held to the deck with four through-bolts but also bedded with some sort of goop. After removing the bolts I had to get a lever under the windlass to pry it up from the deck.

Not sure what the metal rod would be. Is it attached to the windlass? Attached to the bottom of the anchor locker? Maybe some sort of brace to take some of the windlass load from the deck? Pictures would help.

Re: anchor windlass disassembly

it is vertical in orientation.
the four through bolts have been loosened and no longer seem to be the limiting factor. the base plate above deck is loose, and the gear box from below where it attaches to the deck from the same bolts is also loose.
the "rod" is veritical in orientation, right in the center of what I think is the gear box, and extends above deck. it may be a gear type piece to rotate the gipsy. I have looked above and below to find a way to loosen and see none.
thanks for any help as I don't pretend to be a mechanic, but am going to give my best a for effort.
cheers,
keith

Re: anchor windlass disassembly

Well I'm slowly figuring out what's going on. Sounds like you have a model with a vertical axis drum/gypsy with a below the deck motor. The rod you describe almost certainly is the drive from the motor below to rotate the drum above.

At this point you really need the manual or someone that knows this particular model. So #1 priority you need to figure out the model, the exact model. S-L made several vertical model windlasses including the Anchorman and a couple of different Sprint models.

There could be a set screw holding the shaft in place, a circlip or it could be designed to slide out with the motor assembly and is just corroded in place. I would not use any force until I knew how this thing works or you could tear it up.

So, first step, figure out the model. Second step, ask for someone that knows this exact model or find the manual. If you don't have it or can't find it go to Homepage | Simpson Lawrence Yacht Parts & Spares who is THE source for old S-L parts and repairs. He used to be manager at S-L in the UK and bought out all the old stuff when S-L dropped them. You can view or download a diagram of the windlass free at his website or buy the complete manual for 10.00, $15.30 at today's exchange rate.
