Re: [Amel Yacht Owners] Re: Mainsail outhaul gearbox [2 Attachments]

Wow Mike, I replaced my worn origional gearboxes and had no problem with the outhaul shaft. My plastic mounting spacers look a tad fragile for the bottle jack anyway. Now the mail furler shaft was more challenging. I tried tapping it out but very quickly realized it was aluminium and was mushrooming from my efforts. I took it to a machine shop where they used a press. I too was liberal with the antisieze during reassembly.
A quick thought, is the bottle jack pressing on the deck? Is there sufficient support under the deck for the potential full capacity of the jack? Obviously you didn't have trouble but if the shaft were really stuck 4 tons sounds like a lot of load on the cabin top.
I have the older Bonfiglioli gears, which incidentally required no shaving to fit on the boom or main mast. I also drilled and tapped holes for grease fittings..ala Bill Rouse.
My original gears were both bone dry, the main furler gearbox pinion gear bearing had disintegrated into red dust. Previous owner apparently applied grease only to the outside...
The Bonfiglioli part numbers cited on the Forum were correct and gears were obtained directly from local Bonfig dealer in South Carolina and matched boat parts perfectly. I think price was $216 USD.
Sorry... I rambled a bit.
