Problem,
I was playing with my motor today and realised that there was a propane leak under the hood (dual fuel) The fuel lead into the propane tank sheared. Now, the PO of the propane kit used brass 90* fittings in the Isco to make it work better. And they appear to bond to the aluminum housing of the vaporizer. How can I get the last piece of threaded brass fitting out of the aluminum vaporisor????
I'll post a pic tomorrow if that helps.

I do not want to use heat (propane/fire + the aluminum thing). I have tried a easy out (garbage) they just bite further into the brass. I am kinda against drilling the piece out and retapping but if that is what I will have to do then what is the best way to plug the vaporisor to keep brass pieces from getting into it??


Ideas???

:confused:

What kind of easy out did you use? I have seen ones made for softer metals that have four flutes that are just straight tapered splines basically(instead of the spiral fluted) and grab the brass much better. kind of pound them in and put a tap handle on them.

Other option is to try to braze something inside it like a bolt and back it out then... Just be careful with heating up the part...

I remove broken brass fittings all the time at work with easy-outs, peice of cake most of the time. I realize that this does'nt help you, but that seems to be the only good way to remove them.
Brass and alluminum will corrode and bond together prety good, so a little heat may be in order. I had a temp sensor on a alluminum intake manifold do the same thing, it was so corroded and jammed in there that I had to drill and re-tap. I feel for ya!!

here is a pic of my problem

And another...

Thats a perfect example of some of the broken fittings I remove with easy outs. Try it again, for me! Use the largest easy out you can fit in there.

Jeff, it is easier to use the straight easy outs then the fluted ones???

Or the other type?

I am using this type currently... But I absolutely hate the dam things....



Also, is it possible to get aluminum fittings or is something else better to use???

Any one???
:confused:

Which is better fluted or straight.

And aluminum pipe fittings???

I have found that the pro straight flute easy-outs work better on soft metal....(i use proto)
the left-twist ones tend to cam out on what you are trying to remove and make the situation worse..
I would try the easy-outs first..... then failing that I would go and buy a left-twist drill that is tap drill size for the thread..
1/2 NPT = 23/32
3/4 NPt = 59/64
sometimes when you do this the remaining piece will thread out with the drill:)
if not then you can remove the remaining bits like pulling out a spring(kinda unwind it...)

As for aluminum fittings I think Aeroquip is where you need to look
