Yes, I realize this is an old thread, but it ends (so far) with an unanswered question...
I removed my port-side Harken ST 40 winch today to deal with a seized gear & pin. The "rubbery glue" that seals the water out is silicon rubber. This is the first time it's been removed, so it was done this way by Jeanneau. It's definitely not a serious adhesive like 3M 5200.
You definitely do NOT want to use 5200 to bed a winch! When you put it back on, you should use butyl tape. |

Or a less permanent sealant like 4000 or 4200. My preference.

Great hand book for us. The big question for me will be : how frequent would I treat my winches having no sign for problems ? Mine were taken care 8 years ago, model 2005 means half way. How frequent to go ? Am sure some or most of us fellow boaters ,never bother take those winches apart.  ?? |

Harken gives different advice on different pages on their site: either every other year (normal use) to every year (extensive use), or every year (normal use) to twice per year (extensive use).
I think it depends on how you use the boat. If sailing 2-3 weeks per year in fair weather, you can probably wait 8 years without problem. If you live on the boat and sail in heavy seas with salt water spray, twice per year.

I had always thought it was necessary to remove Harken winches from the deck to service them. Certainly, to do a really thorough job of cleaning and lubrication, you do. That’s why I waited so long to do it the first time. But Harken has a YouTube video showing a simple procedure that leaves the main workings on the deck. This is very easy and took only 30 minutes the first time I tried it. It would have even been less if the winch were cleaner.
The bottom line — I will do mine once a year. That should be more than adequate in a fresh water environment.

It's just older designs that had to be removed. |

As noted on page 1, Ive had the pawls start to slip on my older bararossa 40's, pre Harken buying the factory, Change the pawls while tacking upwind in a race! Granted not a thorough cleaning greasing etc, its very easy to do on the combing, cabin top without removing them.
I try to do mine about once a year, especially the 40s that get all the genoa sheet work.

Hi all.
One of our Harken 44's seems to have a very stiff centre screw. I can not get it out. Putting too much torque on it just turns the drum. Tried to stop it turning by running a line to the other winch but don't want to put too much lateral load on the other one. Liberal spray of wd40 yesterday will try again today. Any tips anyone? I suspect if the top hasn't been off for a while, it may need to be checked. The other 3 looked good.

Got it off eventually. Looks ok. Grease might be bit older than others. Will need to do something

That is not correct for Harken winches. Every single moving part of the winch is easily removable using just a screwdriver and 2 differently sized Allen wrenches. I do this every second year or more often on my 4 winches and have also done so on the Harken winches of the previous two Jeanneaus. I use a big aluminum cooking tray to hold all the bits and pieces in one place and to ensure that no grease gets in places where it shouldn't. |

Can you tell me where the Allen screws are located? I didn’t see any, but then, I wasn’t looking for them. |

Maybe it depends on the production year of the winch but on my 2002, both the 32 and 40 self tailing winches have some gears, bearings and a spindle located inside the center stem that if I recall correctly would be difficult if not impossible to disassemble for cleaning and lubrication without removing the winch from the deck.

The smaller winches are not completely serviceable with the winch still on deck, while the larger are. I don't know exactly which ones.

...Can you tell me where the Allen screws are located? I didn’t see any, but then, I wasn’t looking for them. They are not visible until you take the top off. Look inside the centre of the winch where the winch handle goes in and you see a slotted metal screw at the bottom. A wide screwdriver that spans the hole in the middle of the screw will let you unscrew that piece and then you can lift off the top part of the winch. That exposes the 3 or 4 screws holding down the rope stripper assembly. Take a picture or note in which direction you want the rope to be stripped off since you can re-install it several ways. I just remembered that there's a video of the whole process at that does a much better job of showing the steps. I remove all the gears as well as taking out the pawls and while it looks like a big jigsaw puzzle once all the pieces are separated it really is quite easy to put together and no part will fit in a place where it doesn't belong. |

I have Harken “classic” ST 32 and 40 two speed winches. The disassembly procedure is quite different compared with the Radial style in this video. Maybe I was right after all. I’ll take a closer look later this week when I’m on the boat.

I’ll take a closer look later this week when I’m on the boat. The "tower" in the classic model that contains the central shaft is part of the base. To service the central shaft and its gears, you have to take them out through the bottom, which requires removing the base from the deck. |

We did our winches this year. This was a great video. We didn't take the base off as I was worried about leaks, but it can all be done in situ. James

This is a helpful video. My radial winches turned out to be readily serviceable from the top without removing from the deck. That is, of course, until a bad lead ruined my plastic base (skirt, according to Harken) and I did have to tear down the winch and unbolt the skirt (bade) from the deck to replace it. I was really glad that something removable was used as a sealant!
