Found a manifold for my B off a super A at a reasonable price. Good shape except that the stand pipe had rusted away. The treads need to be cleaned out in the manifold to take a new pipe.
Am I right that it is 1 1/2" pipe thread? I'll have to drop it off at a shop to get it done.

| You know that is pipe thread? It isn't very likely a machine shop (esp an engine machine shop) will have that size tap. Even a plumber probably won't have it because most of their work is cutting external threads.

| if you have a steady hand you can take a dremel with a cutoff wheel and clean the threads up that way,the one i did this spring the threads were flat and would nt screw in,it fits good now.

| I guess I could cut the pipe but from the looks of the threads I don't think it would work very well. I'll just have someone run a tap through it.

| Cut some vertical slits in your spare pipe and use it to tap the threads in your manifold.

| Doesn't seem like much left in there from the old pipe. I can see the threads but there is a little garbage left in there. Maybe I'll wire wheel it before I take it in to knock off what I can.

| I did the exact same thing a week or so ago on the manifold on my Farmall 240 I'm restoring. The old pipe was rusted very bad and the PO had just put a thin wall piece of tube over the outside of the existing one which was rusted in the manifold. There was enough metal left in the threads that I took a small pin punch and collasped what remained of the old original pipe in the threads inward. Worked it loose and removed it from the tractor and chased the threads with 1 1/2" pipe thread tap. Manifold is good as a new one and probably much better as it is the original IH made in USA and not some China poor misfitting one from Asia. You are on the road to success, Hal.

| Yes thats the size take it somewhere and let them clean the threads.

| That's what I thought it was from previous reading but couldn't find it. I went to the local hardware store and bought an 18" piece of 1 1/2" pipe that is threaded on each end. I'll just cut it in half so I'll have an extra but I'd rather spend $13 on two pipes than $20 for one.
The pipe was a little too big to fit in the existing threads and it looked like the threads were just covered with rust/crust from the former pipe. I'm going to take it to a local machine shop and they should be able to clean it out with a tap. Thanks!

| If you have a plumbin supply shop they would do it for 1/2 machine shop price.

| I think that is correct, its been a while since I had to fix my SA's manifold. Be careful not to force it, that old, brittle cast will break easily. (My $0.02 worth. jal-SD)
