I pulled the screen out of my air cleaner, this is what it looks like after soaking in the parts washer.

When you think about it , that was all air-born dust that the driver was breathing also. Tractor screened out it's "death dust" but what about the operator? Lot of us are lucky to be around yet.
 
A huge boat load of crap! Did that in the late 70s on an Allis Chalmers "C" engine on the farm. You can see a lot of that crud is seeds? they float and can float through the oil and up into the screen. Glad you did it and washer her out good. That screen should un role. Soap and hot water with a nylon bristle brush. I took one apart on an old mower motor and the screen was Bronze! Have fun.
 
How true. got a cousin that loved his open station tractors, but had to upgrade to cab & filtered air for that very reason.
 
I would recommend taking an oil bath apart once in a while and doing that, I am converting this to a paper element cleaner.

The tough thing is the plate that holds it in was spot welded to the outside of the can, I had to grind the welds off.

Lots of nasty stuff floating around in the air we breathe.
The amount of air a tractor sucks up in 1 hour is greater than the amount we suck up in 10 days.
Our maker figured some nose hairs equipped with a moisture laden dust trap was right for the job.
Maybe John Deere will read this and design a big nose to mount in front of a turbo.
Then they could make there next fortune selling everyone intake fluid. :)
 
David G,

Thanks for the post and picture.

A few months ago I bought an old style Ford 4000 tractor (1963? - serial number has been obliterated by battery acid leaking down onto the place where the serial number is supposed to be). I changed all of the fluids when I got the tractor and pulled that screen mesh out of the oil bath air cleaner. It cleaned up pretty well with gasoline and compressed air, but it was pretty tough to get the screen put back into the cleaner.

Pretty neat old machines aren't they?

When I rebuilt my Super M I steam cleaned that filter until I thought it was clean, then ran solvent through it for a couple days and steamed it again, then it set along the wall in the shop for a couple more years, when I picked it up to paint it the bowl still had a bunch of those little red things of a corn cob that fell out of it.

I sure like oil bath air cleaners more than paper filters. They just keep on working even when abused. Paper filters, not so much. I think paper filters were just a cost saving move for manufacturers, especially in high dust environments. I've never cut one apart, just soak them occasionally and back to work. Unless they are really plugged they have more capacity than is used.
 
That's one of the most neglected items on the old tractors. Strange, the way some are built, it's like the mfg didn't intend for them to be cleaned!

Never tried it, but for a parade tractor a K&N would be a good choice. Might even be able to hide it inside the original canister. Wouldn't recommend it for a working tractor though.
 
I picked up a filter for my N that came without one.
To get it apart had to melt the lead that held the bottom on.
Picture shows after soak cleaning but before air pressure cleaning.
Bottom 1/3 looked like this.

There are several reasons manufacturers when to dry filters. The main one is that once engines got bigger than a couple hundred horsepower, oil bath filters had to be huge to handle the volume of air required.
