:usaflag: Got The Dual Field Coil Cover In And Installed It Today!

[Cupajo]

In a recent post I mentioned that the coil cover was getting thin and after inspecting it carefully, I decided it was overdue replacement.

It came in from White's yesterday and a slow schedule today allowed me to remove the old cover and install the new one.

The old cover was set in a bed of marine silicone and I was sure it would be a beast to get off the coil.

As you can see in the pics, the glue didn't stick to the coil, but stuck very well to the cover.

This allowed me to cut and peel what was left of the old cover and to clean the coil for the new cover install.

The coil is in excellent condition except for a bit of wear on the outer edges attesting to the need for protection .

I'm certain that this coil would be ruined by now without those vulernable outer edges being protected.

The silicone acted as a gasket and kept water and sand out, but I wanted a "permanent" cover.

I know from the coil ear repair I did a year or so ago, that Goop glue will stick very well to the coil plastic material.

I'm not sure if it will stick to the cover plastic, but I suspect it will.

No matter anyway, because I plan to never remove this cover again if I have to protect the coil with band-aids forevermore!!

The main wear point has been around the outside edges of the cover and I shall carefully protect those edges in the furure.

The rest of the cover wears, but again can be protected to keep the cover from wearing completely away as it almost did this time.

The new cover is set in a bed of Goop which I spread with a flat wooden stick to even thickness and it took 21/4 large (3.7 Oz.) tubes of Goop to do the job.

The cover went into place easily with just a small amount of Goop oozing around the edges.

After the glue sets for a day or so I will start using the detector until the surfaces get roughed up a bit and then I'll apply either more Goop or a coating of Marine Epoxy to the cover as additional protection.

I'll test the Epoxy on a scrap of the old cover to be sure it will stick to this plastic.

Stay tuned for further developements Friends,

CJ

what did u use to remove the cover ..a granade my dual field should be here by the weekend i hope i has a cover on it ..hard to c from the pics on feebay..


is the cover same color as the coil??

My coil is yellow, the cover black.

DF's come with a cover if I'm not mistaken.

Mine cost about $15.00 plus shipping which was almost as much as the cover!

I carefully peeled the cover off in pieces to avoid damaging the coil.

The Goop doesn't cure very well when covered with a large layer of plastic and may take several days to set up.

I carefully applied a series of clamps to the coil/cover and about 1/3 of the Goop oozed out from wherever it could!

So far so good.

Thanks for your interest and reply,

CJ

Goop is not a glue I would recommend to put on a Dual Field coil cover!!

It has to be carefully applied to insure a good bond/seal.

The coil/cover combo has to be clamped with padded clamps to squeeze out excess glue requiring great care to avoid cracking the top part of the coil.

I found out the hard way, by using an unpadded C-clamp, that this part of the coil is thin and cracks easily. (Fortunatly the damage is small and shouldn't be a problem to repair.)

The clamp was the last of a dozen I had to use to get an even distribution of pressure and the only one to cause a problem. (Maybe the plastic was weak there?)

Goop sticks well enough, but is a real mess to clean up.

It smears when fresh making wiping off excess nearly impossible.

When dry, excess in blobbs and puddles have to be scraped/cut off/peeled off.

After perhaps several hours of clean-up I will have to go around the seam and add Goop to close any voids.

Looks good and will do the job, but I'm sure there has to be a better way!

Now I have to decide how I will coat the cover to keep it from wearing out!

Stay tuned,

CJ

PS The top of this coil has a lot of accumulation from past attempts at protecting the bottom. Truck bed liner spray among others and a little Goop normally wouldn't be a problem, but I have to clean as much as I can of the top surface to coat it with what-ever I decide will do the job and hope it will stick.
