Lofrans Tigres Windlass gipsy
|
Last season I found that my gipsy slipped despite tightening the wing nut down as tight as I could (used a few taps from a hammer at one point). I've owned Celtic Cross for one season and I'm going to pull apart the windlass for routine maintenance using Alexander Von Uster's excellent maintenance photos. The question I have is whether my gipsy is simply worn out and needs replacement or will the maintenance routine restore it to full functionality? It's essentially a clutch so it looks like it can wear out eventually.

Hi Dave, The gypsy sits on a cone. If it encounters too much resistance it is designed to slip. You might check to see if the chain in the locker is jumbled and kicked. Fair Winds Eric Kimberlite Amel Super Maramu #376

You may have a problem with the key way on the inner cone. Mine was a bit twisted. If is damaged it may not engage the cone. I replaced the shaft, inner cone, all seals, oil, keyways, All parts are available.

Thanks, guys. Yeah, I looked at that photo in your book, Bill. I should probably pull the gipsy off next time I'm on the boat just to see if I need to order some parts. I guess I can see where if the key is distorted I may not be able to fully tighten the gipsy.

The worst case, a machine shop can cut a new key slot 180 degrees from the current slot and you can get a new key. Likewise, a machine shop can enlarge keyways and make a key to size. GREASE THE CONES.😀 If anyone does not believe the cone should be greased, read this from your Lofrans Manual:  Bill

I would order a new inner cone and the service kit. If your keyway looks like the one in Bills photo you will have a difficult time getting it off the shaft.

The service kit has new screws for the access plate to be able to remove the shaft. These should be replaced as the old ones can be challenging to remove.

HI David The key is the second line of defence for the gearbox of the anchor winch. The first is the cone clutch which slips if the winch is overloaded. If it is tightened too much and the operator is brutal the key will eventually fail and sheer off. This is the last line of defence for the gears. Anchor raising should be done in a manner that is sensitive to these facts. Regards Danny SM 299 Ocean Pearl On 25 February 2021 at 12:51 "David Kurtz via groups.io" <Davidwkurtz@...> wrote: |

Good morning Dave, Thanks for the compliments! I was going to mention the key on the shaft, but it has already be mentionned by several people. I bet this is where your problem comes from! Sincerely, Alexandre (and glad the illustrations are useful)

I have found that if I add too much grease to the cone/gypsy surfaces, they slip past each other too easily and will not have enough friction to haul up the anchor. After wiping off much of the excess grease, the proper functioning was restored. The anchor would haul up without slipping, but the gypsy would slip as intended if the pull weight became too strong. Moderation in all things!

This is somewhat related. I find that sometimes when I try to drop my anchor the windlass will not turn and just makes a clicking sound ,I have to pull down on the chain to get it working .What causes that ?
Thanks,
Pat

The cause is that the chain builds up like a volcano then falls on itself, making it difficult to exit via the motor. Normally this volcano building is mitigated by the vertical wall in the middle of the chain locker. The ratcheting is caused by the built-in ratchet mechanism which is needed to operate the windlass manually. There is a longer version of this explanation, but it is boring.😀 Bill
