 Topic: Steel straight pipe
Posted: 20 Apr 2010 at 10:13am |
I need this thing out of my B manifold!
Previous owner stuck in a steel pipe (Although he did cut the groove in it) but I can't get it out to put in a true B short pipe.
Any ideas so I don't mangle the original manifold? The pipe isn't rusted at all, but maybe they pounded it in...it's tight! I haven't soaked it yet though.

Try soaking it. Its probably rusted in the manifold.

C175 - If soaking don't get it. Try a pipe wrench to twist out. If that don't work, cut off flush with top of manifold. Use a plug chisel and peel it like a can. That should get it. Last resort is to use a dremel with a 0.030 cutting wheel. You just need to be persuavive. - AL

I'm just afraid to bust the manifold....
I'll soak it and try the wrench, I just use it about everyday so it's hard to let it sit!

Torch. That'll cut befor the cast. You can cut it off and then cut down the inside to split it. Exhaust will blow out the mess.

I would cut it off flush with the manifold with a hack saw and then use a hack saw blade with and end holder or a die grinder to get it if I didn't have an air hammer with a exhaust pipe cutting chisel.
I just cut one off an Oliver with the air hammer and it took all of three minutes or less if it is exhaust pipe and not well pipe. Mine was on the outside but the inside would go just as fast if it is exhaust pipe. If it is well pipe then the torch, die grinder or hack saw would be the way I would go.

I would go Lonn's route first with the pipe cherry red at the base then let cool and try to twist it out.
I just don't have the nads to cut it out but I know a guy that does it all the time with 100% success for me.

Cut pipe about 1/2 " above manifold and weld a bead around the inside of pipe, below top of manifold. The weld will shrink the pipe as it cools,,,, have used this method many times removing bearing races that were stuck in housings.

I like Tmillers' idea. If it's like mine, there's a lot of crusty rust between the manifold and the pipe. Welding a bead around the inside of the pipe will shrink it as it cools. This should break the rust loose as it goes, without getting the manifold too hot in one area and risking cracks. After it cools, take the pipe wrench and twist. It should come out. You may also try clamping a large pair of vise grips on the stub of exhaust pipe. You can then twist it side to side while tapping upward on the vise grips to gently ease it out.

I'll second the vote for Tim's idea. It is probably the easiest and quickest, and poses little risk for manifold damage. Just try to avoid using 6010 or 5P electrodes unless you are careful/experienced.
