[Farmall] 1949 H Exhaust Pipe

[Gwinn, John J (GE Transportation)]

>From my experience, there is no adhesive product for the application you describe.  The original manifold was threaded for two inch normal pipe thread (NPT).  The manifold threads need to be "chased" and a new threaded pipe stub screwed in-place.  Such a repair will give you an adequate exhaust seal and provide sufficient support for your muffler or exhaust pipe.  Such a repair is fairly inexpensive and quick to apply.

Subject: [Farmall] 1949 H Exhaust Pipe

Got a problem.  The exhaust pipe on my 1949H broke lose from the manifold recently when I hit a bump.  The pipe is 2" black iron pipe, and a previous owner had apparently not welded it very good to the manifold.  Someone in my tractor club suggested grinding down the end of the pipe until it fits inside the manifold and drive it in place.  I did that, but afraid of breaking the manifold driving it in I decided to seat it good and try to seal it.  I've tried two different compounds:  a muffler sealer from a parts store and JB Weld.  Neither held up under the heat.  I don't think a welder is going to be willing to try to weld or braze it back into place because of the proximity to the gas tank and other meltable things, and I would prefer not to take off the manifold nor the gas tank due to the time involved.  Does anyone know of a sealing compound of some sort that will stand up to the heat at the intersection of the exhaust pipe and manifold?
 Guess I'm looking for a quick, easy fix here if one can be found to prevent extended down time for repairs.  Thanks a bunch, Tim _______________________________________________
