Harken Mark IV extruded foil replacements

Anyone just replaced just one of the foil sections. Seems we were hit by a large bird which severely dented ours 3 feet from the mast head preventing the furler from working.

If so where did you order your part from?

Re: Harken Mark IV extruded foil replacements

that's a big bird. Are you sure it is bent or are the sections loose and coming apart. Any one that sells Harken can get but some want extra shipping because of the length. I have ordered them thru West marine and had it shipped to the store for pickup, no shipping cost or extra length shipping cost that way.

Re: Harken Mark IV extruded foil replacements

You are probably looking for a MKIV series 1 or 2 foil. The MKIV foils are different from previous units. You might be in luck as the top foil is usually shorter than the 7' standard length.

Yes it's the top foil of a Mark IV unit 1

It's severely bent you can noticeably see it

Only bird I could think did it is an owl. We have two in nests near the marina. They are huge birds .

Maybe he hit it

Regardless it is bent good enough to affect it turning around the forestay

Re: Harken Mark IV extruded foil replacements

The parts list is at http://www.harken.com/uploadedfiles/...F/mk2-1-pl.pdf

You probably need a 807 luff foil. The top foil is usually shorter than 7' so it is cut at time of installation. Any Harken dealer can order one of these for you.

If it were me, I would drop the whole unit. Past experience with separating old foils is to use a heat gun to warm foil at joint to soften the loctite used with screws and connector wedges. A light tap will also help break the connection loose. You can cut the replacement foil to length with a hacksaw but found I had better luck with a Dremel EZ Lock diamond cutting blade. Wrap the foil first with some tape and you will have a nice clean cut.

Good luck

Re: Harken Mark IV extruded foil replacements

In order to take off the extrusions who forestay needs replacing as the swauge must be cut off to slide it off. Probably means a new forestay also.

Rigger must go to top also.

They said the fitting between the extrusions are not usually difficult for them to get apart each 7 foot length costs $80. I have 7 of them

Re: Harken Mark IV extruded foil replacements

don't know why you would have to cut the forestay. most units are installed on an existing forestay. no need to remove the forestay from the mast, the sections are removed one at time at deck level. you heat up the screws with a heat gun to soften the loctite and remove the four screws at each section joint and slide the foil section off.

Re: Harken Mark IV extruded foil replacements

Bottom and top of forestay have swauges so they. Can be attached to toggle at the bow and masthead at the top. The extruded foil pieces won't just slide off with these in the way. Not sure what type of fittings were used

Re: Harken Mark IV extruded foil replacements

that would be a very big fitting to not fit thru the foil extrusion . you need to remove the lower part of the turnbuckle and there should be a swaged on thread fitting. The connectors and bushings fit inside the extrusion and come out before you slide the foil off the wire.

Re: Harken Mark IV extruded foil replacements

Yes I see that. Thanks for the info

I am letting the rigger come look at it this week
If we don't need a new head stay that would be great as that's a simple fix if they can just slide off the whole set of extrusions and just replace the damaged top piece

We have rid rigging and the head stay was replaced when we bought the furler 8 years ago

I doubt the rod is damaged. The issue was being able to get the extruded piece over the bottom swags.
