vertical exhaust pipe fumes

[tinnerjohn]

My Cub had a locknut that's normally used for electrical fittings on the 1" pipe at the manifold. When I replaced the pipe I chased the threads and installed the new pipe but didn't use a locknut because it didn't seem to make sense. After retightening the pipe several times, I put a nut on, no problems since. It's not in the book anywhere that I've seen, but it worked. John

you will NOT find that lost air cleaner cap

Yeah. The soup can does great while not in use but I invariably forget to put it back on and then clouds dump rain when I'm not around to stick the can back on. I guess I'll have to buy a new one - probably $8 with $10 shipping fee.


So the 1" pipe is just some hardware store black pipe nipple that is threaded and I can try screwing it into the manifold and hope that it will set some new threads?

After notching it and using it as Scrivet described.

Hi,
Below is a listing from TM Tractor, for a new air cleaner cap.

The caps are made so they will tighten in the pipe. First, put the cap in the pipe, then I fold up a rag, so it is several thicknesses, then set it on top of the cap, to protect the paint, and hit it gently in the center once with a rubber hammer. They tighten in the pipe, and won't fall off, hopefully, if it is still like they originally were.

I would find a tap somewhere, and repair the threads in the manifold, so the pipe will screw in.

You could remove the cap at the top of the muffler in hot weather, or not raining, it will probably let the exhaust go up farther, that might help keep exhaust out of your face.
Remember to cover the exhaust when the tractor is sitting, don't let rain in the engine.

I just did this. Borrowed a tap from the Lumber Yard where I bought the 1" black pipe (which was 18" and threaded on both ends.) I was surprised at how smoothly it worked. And this was after having to "cut and pry" out the old pipe which had broken off right at the joint with the manifold.

All this with the help and advice of wiser and more experienced members of this forum.

Trust me, and this is from experience...you will NOT find that lost air cleaner cap until you purchase a new one!!!

and then it will miraculously appear in a place you have looked a dozens times before

Yup on Indy's quote. Mowing, saw the air cleaner cap fall off. Immediately stopped. Looked and looked and looked. The cap had to be within 10 feet of where I stopped the tractor. Drove the tractor on the mowed area, actually a tractor path several times since.

Several weeks later, mowing the same area. There it was, laying on top of the previously mowed grass.

But surely only after you had ordered a new replacement including $10 shipping. This is a mandatory step in the process of locating the old one.

not a tractor part but a funny thing, one day I was walking one of my trails, not 40 yards from a game camera, I could see this thing from 200ft away, a humongous shed antler from a buck that was never once on my game cam. After 3 days of looking for the other shed I gave up. Three years later on a trail I had searched many times laid the other shed, a bit chewed here and there but unmistakably the other side. a coyote may have moved it, but it was again, not 40 yards on the other side of my game cam. go figure

on the exhaust, pipe threads are tapered, so its possible you can get the stub pipe to tighten up a bit, one thing you can do is take a torch and "tin" the threads on the stub with some lead, a very thin layer, this might be enough to snug the pipe, solder would maybe work, I don't think the manifold will get hot enough to melt the layer. other methods have included coarse steel wool or even wrapping a very thin piano wire in the threads of the pipe to take up some room. This depends on how worn the manifold threads have become. A more drastic repair might be drilling it out to the next size and rethreading and installing a reducer back to the original 1" pipe thread. Goodluck!

This step is only required if you haven't already driven over it and smashed it into uselessness.

Install an underslung exhaust!

Like he said My 51 had a vertical stack looked cool too but after a bit of seat time a bit green in the face . Underslung not as cool but it functional

Heres the solution I found at the hw store plumbing aisle. I gained a little height with that coupling and extra 6" piece on top of the 12". It seems to have threaded itself into the manifold well enough. I can always give it a twist if things seem loose. The left-facing stack cap seems to help with the fumes too. Came in smelling sweet as a hay field after an hour! Big improvement. Now I'm putting up second post about the smoke/oil I'm seeing around the base of the engine.

Some of you may recall that about a year ago I installed a roll bar and canopy on my Ford 3000. Makes a huge difference in hot weather. But, I did notice that the exhaust fumes coming from my upright muffler were lingering under the canopy. So, I got a tailpipe extension with a curved end and installed on the muffler. I turned the curve to the left. Seemed to have made a difference.
