Line Winch needs Maintenance

My name is Ken Uber, I am the proud owner of a Super Maramu Hull #007 built in 1989
In the cockpit is a line winch that looks unique, but I have seen similar ones on other AMEL’s that were constructed before 1990.
I am seeking any advice as to where I may find some maintenance items for it, as you can see in the photos the white ring is worn.

Thanking you in anticipation

J’essaie de traduire:

Je m’appelle Ken Uber, je suis l’heureux propriétaire d’un Super Maramu Hull #007 construit en 1989
Dans le cockpit se trouve un treuil de ligne qui a l’air unique, mais j’en ai vu des similaires sur d’autres AMEL construits avant 1990.
Je cherche des conseils pour savoir où trouver des articles d’entretien, comme vous pouvez le voir sur les photos, l’anneau blanc est usé.

Merci d’avance

Yes thank you, my education did not include the range of languages that one should have. I am a friend of Google translate. and I love this site, learn so much!

My first language isn’t French either, but out of courtesy I’m translating into French to this french speaking forum using Google.
BTW an english speaking forum for Amel is:

Bonjour Eleuthera, j’ai le même système sur mon Sharki de 1989. La pièce uséee ne doit plus être fabriquée mais une fois démontée, bien prendre les mesures et donner le modèle à un tourneur qui fera cette pièce pour 10 € environ. Je viens de faire fabriquer 2 réas de bôme d’artimon pour 20 € près de mon port (Marans France)
Hello Eleuthera, I have the same system on my 1989 Sharki. The worn part should no longer be manufactured but once dismantled, take the measurements and give the model to a turner who will make this part for around €10. I have just had 2 mizzen boom sheaves made for 20 € near my port (Marans France)

Thank you very much, I will need to do this.
Also one of the two screws in the top is loose., have you had this problem as well?

Merci beaucoup, je vais devoir le faire. De plus, l’une des deux vis du haut est desserrée. Avez-vous également eu ce problème ?

Bonjour Eleuthera,
pour la vis déssérée, ça m’est arrivé, le mieux est de mettre du frein filet sur la vis avant de serrer.

Hello Eleuthera,
for the loosened screw, it happened to me, the best is to put threadlocker on the screw before tightening.

Thank you.
I have attempted to remove the winch from its location, but at this stage the screws are not moving. I am considering how to access the underside, but it looks a difficult job as I will have to remove the roof lining to get there, unless there is something else to try.
As for the loose screw, it took it out and it has actually broke about 1/2 way down. This will a challenge, but I will find a way, but first to remove the winch off its base!.

Any suggestions gratefully received.
