Curved exhaust versus flapper

stuckmotor · Mar 16, 2013

Has anyone ever stuck an engine because their tractor was left out with an uncovered exhaust pipe that had a curved end? How about with a flapper? I've already gotten one motor stuck and don't want a repeat performance.

Flapper with a half a soda can on top. A soda can works good because if you forget it is there the exhaust will blow it of.

Ted,
Do you cut a slot in the soda can for the counter weight on the flappper? My Massey came with a flapper and I couldn't get anything that small over it.

I'm sorry for your loss. Which did you have on the Honda, curved exhaust, or flapper?

Ted Summey · Mar 16, 2013

I've been able to mash the can to fit over the counter weight but it it is on a Farmall 140 gas exhaust. I think a slot on one side would work. A set of tin snips would come in handy.

The Kubota has exhaust under the grille out the front. The MF 135 has a curved exhaust but stays under the shed (the others usually do unless I am working a food ply or hay and need to leave machinery in the field)

Thanks,Ted. I imagine the 140 has a smaller exhaust and flapper.

Stuck a old jeager pull behind air compressor. Had a straight stack on the continetal motor. Pop can over pipe using electrical tape to keep it on. Come spring the motor would not turn over. Crack on the manifold where the stack mounted-filled her up with water. No more sandblasting.

I like flappers personally. Just installed a straight pipe on my splitter, so far the flapper is working perfect.

The upright stack still will have moisture in it when it cools down. This comes from the combustion gasses cooling down and depositing on the walls of the stack. To get an idea how much that could be watch the horizontal tailpipe on your car or pickup. This amount should not affect the workings much.

I've had a few mufflers rust out on straight and curved exhaust pipes that go up. Now I put a plastic coffee can over the top when I'm done with it and that seems to solve all the problems of water getting in there.

Your being silly. No such thing as a plastic coffee can

Folgers coffee. Plastic. You can't make Cowboy Coffee in it but it is useful for storing brass when it's empty.

Some of my British friends call cans, 'tins'. I don't think they've figured a way to make them out of plastic, yet.

one of my old neighbors had an ugly Iron fence made of plastic you know

I find the flappers a pain, they are noisy. What I do is use the curved pipe and mount a can to a stick, when you shut it off put the can over the tip, with the stick on it, there is no problem of it blowing off and it keeps the moisture out. Best of all it is cheap!
Just a thought!

stuckmotor · Mar 19, 2013

John,
I can't visualize the can on a stick. Could you elaborate?

Johnp33 · Mar 19, 2013

They Drill a couple of holes threw the board and Can, measure the spacing, put in a couple of machine screws with the heads on the inside and you are good to go. I have seen them with plastic jugs, what ever will fit on you stack, cut the board to what ever length you want, that is easy to remove, and stable in a wind.
2x2s work great in most applications.
Just a thought!

So, the stick is screwed to the side of the can to, add weight and keep, the driver from having to climb on the tractor to put the can on top of the exhaust?

I have my neighbor's 630 JD in my shop rebuilding the motor because the can blew off and filled the cylinders with rain water. I prefer to use a roof over the tractor to prevent water from getting into the exhaust manifold. I like the can on the stick idea for a tall tractor and the weight of the stick will keep the can on the pipe if you don't have shed available. It still does not protect the water from wicking down the pipe below the muffler section itself into the manifold.
