Muir Hercules Manual Windless

I have a Muir Hercules Manual Windlass on a new to me 1986 Pacific Seacraft 34. I've only had the boat for a few months and have noticed what appears to be grease leaking from the windlass. Presumably this isn't supposed to be happening. Can anyone help me out and give me any idea (1) what is going on and (2) how do I fix it?

Thank you!

Re: Muir Hercules Manual Windless

Iím going to ask a dumb question, but is it grease? Does it feel like grease? It rather looks like rusty moisture. Perhaps using it is forcing some water out as the grease inside is redistributed after sitting stationary for a while?

I have the same on my Pacific Seacraft 34. It works quite well just as long as you tap the gypsy to release the brake. The windlass is supposed to be sealed and pretty much maintenance free. If it is really leaking grease, then the seal must be broken. Some time ago I came across the following link: s/v Bella Star: Windlass Rebuild about rebuilding the windlass - may be helpful.

I have a similar design manual windlass. Itís a great piece of equipment. Itís gears are in an oil bath so it appears your seal is broken. My 30 year old windlass was completely reconditioned last year and now works like brand new with zero effort

I sent it to floridariggingandhydraulics.com.....excellent customer service and great job. Give them a call.

More than likely it's fine, but as others have said, the bushings are leaking grease. At some point that could allow saltwater to intrude into the housing and after further time it could cause a failure. The Muir looks almost identical to the SL-555 (Seatiger), and I can tell you, from having rebuilt the Seatiger on my PSC34, that it's seriously overbuilt. So failure is probably many years off.

Still, I wanted to make sure that I wouldn't have an issue, so I rebuilt mine. I don't know if there are parts as readily available for the Muir as there are for the Seatiger. I was able to find new bushings (at a pretty hefty premium) and other parts, even the original grease that was used to fill the case.

If you can't find any spare parts for the Muir, you could still disassemble, clean, and then reassemble and fill with new grease. It would probably still slowly leak grease, but at least it would take another decade or better before you had any problems. I wrote up a little description, with photos of my rebuild and I can send it to you if you think it might help (it is on my website, but the site is currently down and I won't have it back up for another week or better). PM your e-mail address to me and I'll send you the write-up.

Re: Muir Hercules Manual Windless

I think you are right- not grease at all. Its probably been 15 years since the windlass was used, so your explanation makes sense.

Thanks!

Bill- I don't have enough posts to send you a PM. But thank you for the offer! If you can post the link to your website I will check it out when it goes back up.
