It’s funny how things come along in twos and threes. Nobody has mentioned furler bearings to me in years, then two teams ask in two weeks.
Basically, an FF generates higher rig loadings than a dinghy and the furler bearings need to be high grade or high tensile or one of those expressions. If you have a bit of a rumbling in your bearings you should change them top and bottom. This is the critical thing – you need to get the high tensile bearing set. I’m pretty sure that these will be hard to find at Chandlers that don’t have a Flying Fifteen speciality and you’ll get fobbed off with the wrong thing. They’ll melt in the sun (if we had any, says John Hassen !!), … or worse.
So what you do is call P&B to talk it through – they (i) understand the issue (ii) stock the right parts to get you furling again. How do you get in there?? Well, do you know I’ve never had to do it in 20 years so I can’t say from personal experience. I think there is a circlip that you lever off and that’s how you get “in there”…..
