hi all

trying to rebuild/replace this furler (damaged in a storm last year - does not spin easily, must be furled manually)

the foil is continuous rectangular plastic (rounded edges)

does anyone know what this thing is? or what brand would be compatible with that type of foil?

seems very vintage/antique - I am just trying to get it to a functional state for the rest of the season

thanks! (pics below)

Hi Rolf,
Looks like it might be an old CDI by the small cleats near the furler drum.

Not sure what you mean ?
If it is the CDI flexible furler, there's precious little to rebuild.
There is the internal halyard and a thrust washer in the drum.
What parts are you looking to replace ?

I thought there was either a ball bearing pack or a solid Teflon race in there
guessing that'll need replacement
the drum is also pretty beat up, although I may be able to bang it back into some kind of shape
main question is: can I disassembe from the bottom end, or must the whole assembly be off the boat?
thanks

Yes, the CDI Flex Furler can be disassembled while still on the boat.
You will need to release the forestay when you do this.
Be sure to remove the mainsail and boom from the mast to minimize the weight pulling aft on the mast.
It would probably be a good idea to take the sail off the furler also.
Attach the jib halyard to the bow pulpit and pull it tight to support the mast while the forestay is disassembled.
You will need a pair of locking pliers to mount to the forestay to support the weight of the furler shaft when you disassemble the drum.
Finally, set up a box, bag or some other device to catch all the little pieces on the furler when you disassemble it.
I've done this myself on a Cat 22. It's possible, but not very recommended.

I found no thrust washer on disassembly, plus wear atop the HDPE bearing
anyone know the specs on that washer? guessing the bearing should probably be replaced?

also, does anyone know the preferred angle/cofiguration the furling sheet *should* take when exiting the furler drum, for maximum leverage/purchase?

thanks!

The preferred angle should be 90�

The thrust washer is item M on the following drawing, part no 1253

Rolf,
Just a thought, but in order for everything to move smoothly inside the drum, do you need to smooth out the aluminum drum somehow? Looks pretty dinged up. A ball peen hammer comes to mind as does a 3/4" rounded end pine dowel for coaxing the can back into shape. A little shot of silver or white spray paint would make the the renovation complete.

yes, I banged the cup back into shape - everything good, except no thrust washer - trying to find a 2.75 OD x 1/8" SS washer - actually found if locally, but they closed before I figured tzhat out, and I gotta leave town before they open on Monday - grrr

back together, and working great - had to rotate the cup 90� to use the alternate (unworn) bolt holes - fuling sheet going outside the first stanchion, which I'm not sure about, but seems to function well that way

Note: the thrust washer size is *not* 2.75", as CDI told me, but 2-5/8" - best match seems to be an M36 bolt washer, 66mm OD - standard part, available off-the-shelf in A4 SS - I temporarily used a 1" grade 8 washer, 2.5" OD
