B250 smokes???

any help would be great thanks

Three of the injectors were malfunctioning and one was just "peeing" on the cylinder. Got them rebuilt for $75 a piece. Wish I had tried a quart of automatic transmission fluid in 10 gal of diesel first...but you know, hindsight and all that.

The air filter was clogged. I found that the tractor smoked little to nothing with the air filter off...just don't run it in the field like that. That was just for troubleshooting.

I'm assuming that you have an oil bath filter. It is probably dry (no oil in the bottom). Take the entire thing off the tractor and put it in enough diesel to cover the steel wool looking filter and let it sit for a day or so. You don't need to rinse it, just let it drip dry.

Reinstall on the tractor and put about a third to a half quart of oil in the bottom section. The air flow pulls a little of the oil up onto the steel wool and makes an efficient dust and grit filter. Service this about every 50 to 100 hours in normal service, 10 hours in dusty.

A clogged air filter, even a paper filter, will affect performance just like pulling the choke on a gas engine. It has the effect of overfueling the mixture in the combustion chamber and smokes up the neighborhood.

These are great little tractors, very powerful for their size. Suggest you get a service manual and an operators manual, about $60 total. They are a lot of help in operating the tractor to the max.

Hope this helps. If not, just ask again, we'll all kick in a suggestion.

i guess i need to get an air filter it has none to clean.

about this trany fluid in the fuel , it wont hurt it??

thanks again

I don't use it all the time, but will put some in the tank before filling to get the mix blended. Seems to get the crud build up out of the combustion chambers, too.

Anyway, I don't get the part about the no air filter. Do you have a canister or nothing there at all?

The thing is, if the tractor was run without an air filter for an extended period of time, grit and dirt may have done in rings, valve guides, any number of oil sealing parts that will have you burning crankcase oil in the combustion chamber, causing smoke.

Now if it just sat for a while without the filter on it, something may have made a nest in the intake manifold and got you clogged up.

Anyway, does the tractor run ok other than the smoke? If so, this probably isn't much of a problem.

Keep trying, let us know how it turns out.

thanks again

Try the ATF in the fuel to clean the injectors, they are probably gunked up a bit, that will improve the burn in the chamber. And get it off idle, but nothing real fast without a load. Mine likes about 1800 RPM for mowing, runs just like a sewing machine, plenty of torque lift when we hit a tough spot, 1200 or so for dirt work, etc.

If I were plowing or disking, 1800, cultivating, 1000 to 1200. Nothing slower, you need the diesel to burn well in the chamber. Diesels will "slobber" on idle, which means that you don't get everything burned and liquid or gooey black stuff may even come out of the exhaust.

Try something. Take the canister off the tractor and look up inside of the canister. You might find the steel wool looking stuff up in there. I tried to take mine out to clean it and found that it was in a container that is welded inside the canister. The bottom part that comes off has a baffle and would only contain whatever oil you would put in. If it is empty, take it to a NAPA parts store or an IH Case dealer and find out what goes in there.

Good luck, keep us posted.

thanks alot for all the info
