Seized threads on aluminum
Sorry, not model A related. I am trying to take apart a threaded joint on an old aluminum gas light and its seized. I have it soaking in acetone-atf solution. Any advice?

Re: Seized threads on aluminum
heat and vibration(hammer taps)
if the head is buggered --welding a blob on the head and letting it cool---a big old red hot blob will heat down aways and loosen the corrosion bond----sometimes I will do this even if the head is good |

Re: Seized threads on aluminum
agree with heat. aluminum galls so easily....good luck. You may end up partially destroying the threads no matter what. when you reassemble, be sure to use some never-seize

Re: Seized threads on aluminum
If you can get the nut off of the thread. Then you can get a piece of thin wall tube that will just fit over the collar. Then using a pair of vise grips grab the tube and work it back and forth forcing it down between the the aluminum housing. Working the tube will act like a saw and cut out the corrosion. Not fast but it works. This was the only way we could get a aluminum head off of a engine.

Re: Seized threads on aluminum
Does the mini inductor II work with aluminum? I thought ferrous metals reacted to induction.

Re: Seized threads on aluminum
Does the part your heating up need to be inside the coil?

Re: Seized threads on aluminum
It works best surrounding the piece being heated... There are different sizes and lengths available including universal wrap around ones ..see the pic
I purchase an aftermarket cheaper coil set not through mini inductor,,, Amazon has them.. The coil can be above the fastener also still heats it just takes longer Most fasteners do not need to be heated till its red hot for removal... Usually just a 30 second hit works Last edited by Mitch//pa; 09-16-2016 at 07:38 AM. |

Re: Seized threads on aluminum
I am not trying to insult anybody, but the original question was not how to get a stuck steel bolt out of an aluminum threaded hole. It sounded to me like it was an aluminum pipe going into an aluminum coupler. Maybe I am wrong but I think the only good answer was to use the induction heating method that Mitch uses. Yay, Mitch.
