Anyone ever straighten a twisted FEL?

Be glad you not doing it on the clock. :thumbsup:

Ya!! Sometimes I get lost in the moment and it appears I sit there longer than need be. OHHHH How I study things!!

If I was a beer drinker I probably could really get it examined!!

Yes there is a torsion tube between them ... I guess you would heat it ike dead center?

Sorta. I would try to broaden the area of heat influence by waving the torch back and forth about 6" along the tube spanning the center. Two std propane torches opposing would help you warm the circumference more uniformly. Im serious about not needing much heat. Since you are preloading the anti tweak highly a little relaxation of the metal will go a long way. Try raising the center portion of the tube to the boiling point and experiment in that area. A wet finger touch will detect sizzle somewhere above 300F. That would be where I would suspect the paint would start to discolor.

The torsion tube has all the metal hyd lines on it ... do I need to remove them? Will the heat get them?

I have never seen a situation were something that basically would not move cold, is going to suddenly become submissive, after you heat it to just 300 degrees.

Well its done ... I got the last out of it. So close its unreal. I will go get pictures ...

Here is what I did today. Chained it down and put the jack under the low side and gave it to it ... nothing just wouldn't move. So I blocked the low side with timbers under it about 16" of them and then applied down pressure on the loader and took the second tractor and loader and came in on the other side and applied pressure down with that loader and ... well its real straight now ... quess I tweeked it back into shape!!

If they are on one side shield them with a piece of sheet metal. You dont want them touched by flame wash

Check back. It had moved quite a bit. Highly stressed metal can easily be very near plastic deformation. A little heat can put it over the hump. Depending how near plasticstress point, a hot day in the sun can move it.
He got it by just using more force tho.

Glad to hear you got it straightened out.

Heres a couple shots ... notice in the 2nd one it even looks level across the front of the tractor.

Thanks Everyone I really appreciate the info.

I spent over 30 years straightening frames, among other things, in the auto body repair business.

So trust me, I know exactly what, when, where, and how much heat it takes, when it won't move, because I have done it thousands of times.
