Do you have one of these?

[Pearson]

I need a new nipple that screws into one of my wing tanks. The external threads on one end of this one are messed up. I suspect I could probably just use a regular pipe nipple and thread the inside of one end. But I would rather find one all ready made to fit.

The pipe part is exactly three inches long. I can use my old finger strainer if I have to.

Anybody???

Richard,

In case you don't find one here is the link to the drawing for a similar L-2 part, length is differrent.

Was this from a wing tank with a wing root valve?

A lump of threaded cast iron that deserves no place in a lightweight Taylorcraft (I've got several of these, removed and subsequently replaced with aloooominum pipe and fittings with a new brass filter, all available from your favourite parts supplier).

I use the old ones as door stops.

Is that as opposed to Al-U-many-um?

Rob,

Yes, it is from a wing tank that had a valve at the root. The valve has been relocated.

If I could find an aluminum nipple, I would love to use that instead of what I have. But I have checked the catalogs I have and see nothing made of aluminum that would work.

Richard, I'll take a photo of my set up today & poat it this evening.

Richard:

Here is the device I have (below). You are welcome to it for the cost of shipping to you from the UK.



BUT:

(Below) is a general view of my right wing root. The fuel pipe from the wing tank goes forward between the wing root and the cabin fabric, and then down the door pillar to the instrument panel (where I have my shut-off valve).



(Below) is a view inside the access panel of the wing root fabric. You can see that there is just a simple AN elbow.



Let me know what you think.

Re: Do you have one of these?

As I was snowed/iced in today I went down to my shop, pulled out my wing tank and can not remove this strainer. I had a box end wrench and a lot of pull. I changed my location of pull to minimize the strain on the tank and put a lot of pull in to it. I have had to take a lot of very tight parts apart in my life but I always had the option of heat, obviously here I do not. Any hints, like a big soldering iron, ice cubes, etc. This tank has not been apart in at least 35 years, maybe never.

Re: Do you have one of these?

Larry,

I had the same problem when I took mine apart. After trying all the usual stuff to get things unstuck I finally decided, "well it's no good the way it is, so if I ruin it there will be nothing lost". I finally just started a steady pull, increasing the force until it broke loose. I did NOT use heat on the aluminum tank. My feeling was that would just weaken the aluminum.

My only suggestion would be, if your tank is out of the aircraft, build up the area around where the nipple goes in with weld. Then grind, file, or somehow shape something you can get a wrench on to use as a back up.

If the tank is still in the airplane, "you're screwed". Crank on it until it either breaks or gives.

Vice grips, squeeze it gently right at threads, wee bit of heat if possilble, penetrating oil , it is a pipe thread , l rattle it with a rivet gun ( gently) directly inward on the end , or tap tap with hammer, I have sold four so far! The finger screen is there on all , some have threads, some not , some need cut to size and threaded. Good luck. I ahve never twisted one out. they usually break free .

Re: Do you have one of these?

Thanks, I had forgotten about both the vice grips and the air hammer. I have used both in the past. I will try both tonight. I believe I have a steel tank, keep forgetting to check. Another idea I have had excellent luck with is applying heat, let it cool over night, apply heat again, let it cool over night, and the 3rd time, apply the heat and then the torque. That has saved my bacon more then once on really difficult cases. Have even put the difficult ones out side in the winter or pack in ice, then apply the heat fast and furious to the outside as best I can, then the torque. Larry

Re: Do you have one of these?

When you use the air hammer remember lots of LIGHT taps is what you want. Hit it as light as you can into the tank while applying torque to unscrew it. Time and light taps will work better and won't damage the tank. Hard hits will damage the tank and high torque could twist the fitting out of the tank. Why risk it. Take your time and NO OPEN FLAMES!!!

Re: Do you have one of these?

Went to the shop, found the tank was steel so jigged everything up to hold the tank securely, screwed a pipe plug in to the bushing to give it some internal support and found a 12 point wrench that was new(not wore out). The bushing was tight but it did screw out without a problem. And yes, no open flame was considered! Mine turned out to be a brass bushing with the screen soldered in so it is very short overall.

Re: Do you have one of these?

Rob, what size are your fuel lines from the wing tanks? George
