Re: [Amel Yacht Owners] Furling Gearbox Differences

hi John,
As I noted, you do have to grind the fins on the SN, Sounds like the SM mast section is a bit bigger.
And, Ian, I had to remove the boom and use a hydraulic bench press to remove the shaft from the line tender. Since it has a woodruff key I did sand it down a fraction when I reinstalled it so next time should be easier. Also, you'll want a proper drill press with long bits to drill the holes. Also, since you'll be opening the unit the factory gear oil will seep out - suggest using grease on reassembly and add Zerk fittings for periodic maintenance. I never had much luck with the paint lasting very long, but your technique sounds good, Wonder if a 2-part like Awlgrip might be more durable. I had though of having it powder coated but didn't want to remove the rubber plug and seals.
Good luck with it,
Craig SN#68

Hi All,
   I replaced both outhaul and mainsail furler bonfig  gearboxes and did not have to grind down either one.  Both were bolt on replacement.

Just about to fit 2 new Bonfiglios. Grinding one
down to fit was easy as it is aluminium or something very
similar. Then you need to paint it. I used an aluminium
etching primer and the two or three one part top coats.

Not anticipating an easy job with the Anderson separation,
but I’ve got everyone’s notes to hand!
