kwaltersmi Wayne - From what I could see, the sheave appeared ok. However, I did not take off the access plates to get a full view. I simply looked down the copper tube with a flahslight. It seemed to spin just fine with the new wire in place. I did not use any lube.

Wayne25 Kevin:

Was your guide sheave in good condition and spin ok? Did you have to lube it, if so how?

kwaltersmi I installed the new winch wire this past Friday just before I launched the boat. I basically used the method I outlined in one of my above posts. The procedure was easier than I anticipated and only cost $21. No worries about not being able to raise the board this summer! Thanks to everyone who contributed to this thread and helped me think through the process!!!

I think that if it were possible to access the sheave pin, I would use something like NeverSeize. That stuff really stays put. But any good grease should work fine.
If it's not easily accessible, I would probably use a spray Teflon grease. It comes out of the aerosol can as a liquid and quickly set up into a grease.
I really can't tell you for sure without seeing it.

Can you see it pretty well?
If you can see it, maybe you can make longer straw for the spray can. Or maybe the stuff will squirt far enough without a straw.
It seems strange that they would design it in such a way that you can't maintain it.
But I've seen stranger things.

Number of Helms 25 owners

Kevin:

I'm not sure how many Helms 25 owners read this forum. On the old SailNet email board, I think there was a at least 30 Helms owners that contributed. I think this is the only board that has any regular activity. Mainly due to you, me and David. If we keep active, it should grow as new owners Google for information.

I'm planning to do the repair on Friday, so I'll let you all (how many of us are there?) know how it goes.

Kevin - When you take the vinyl hose off the bronze Tee at the top of the trunk, look if the cable has worn a groove in the Tee. From what I can see through the vinyl on mine, the cable is through the wall of the tee at its tip and just touching the vinyl hose. I was planing on filling the groove with MarineTex and sanding smooth rather than re-glassing in another bronze tee.
BTY, I bought new vinyl hose for mine. Its 3/4" over the tee then the 1/2" slips tightly inside the 3/4" up to the winch hub. Its nice heavy wall vinyl I got at West Marine. A foot of each and I'll cut to fit.

How do you attach the old cable to the knew? I think that's a good idea and is probably much easier than trying to thread the new cable through on it's own.

Carefully unlay the strands of the ends of both cables. The old and the new. Cut off two or three inches of about 1/2 of the strands of one of the cables and cut the opposite strands of the other cable the same way.

Then lay them up together. If you're careful, there should be no increase in diameter.

Put a thin layer of electrical tape over it and you're set. Just don't pull it real hard. Have someone at the other end if possible to push and rotate in case it try's to hang up somewhere.
If you want to be real safe, soak the connection with superglue before you tape it. You will be able to pull it pretty hard without it coming apart then.

Good luck!

Wayne25 Kevin:

I have 2 - approx 2" x 2" stainless steel plates on the centerboard trunk below the entrance point of the cable. I assumed they are for access to the sheave. When I unscrewed mine, it was sealed with a thick red gasket material. No opening was behind the plate. I could see a faint outline of a 3/8" circle at the edge of the fiberglass. I assumed this was the end of the sheave shaft. I didn't want to disturb it and screwed the stainless steel plates back on. If yours has 5200 or a white caulking, someone might have already accessed the sheave for servicing.
