Bent Profurl Extrusion

Hello all,

I have a Profurl Classic LC-32 furler. It takes quite a bit of force to turn the furler. I have to grab it with both hands to get it to spin at all.

The halyard swivel spins easily. I removed the set screws that hold the drum and was able to separate it from the extrusions, and that spins easily as well.

2 of the extrusions near the top of the forestay are slightly bent, so I'm wondering if that is causing the friction. I'm trying to figure out how to remove the extrusions, but I don't see how to remove the bottom bushing and bushing holder. I've loosened the 2 set screws for the bottom bushing, but it doesn't want to separate from the extrusion.

Should I be able to lift up on the extrusions to separate them from the bushings? Or should the bushings be loose after loosening the set screws?

I've never worked on anything like this, so thanks for any help.

Thanks,
Joe

Re: Bent Profurl Extrusion

We have a Sailspar continuous line furler and it all comes apart ok once you overcome the thread sealing compound on the extrusion jointing machine screws. We managed to take out the worst of the bend by gripping the bottom of the forestay assembly in a very heavy vice on a metal bench. About 6 of us then heaved on the extrusion. To get the extrusion off completely, you may have to remove the terminal fitting at one end or the other.

Also, consult your local friendly rigger and download a manual.

The extrusion on our system has a plastic sleeve between it and the bottom bush and you just have to grip both bits firmly, waggle back and forward while pulling apart.

Re: Bent Profurl Extrusion

In any case if the top extrusions are bends you need to take the whole furler down, , between extrusions ends there is a bushing holding the 2 extrusions with a set of allen screws and inside of the bushing there is a plastic inner busing as well, if they are bend the wire make a lot of friction inside of the bushings, again take the furler down , is more easy to work with it ....
