Air cleaner screen

501 Club
My operators manual is a reprint and my cub is a 1951 F series. The manual under Washing the Cleaner says to remove the entire air cleaner from the tractor but gives no clue to how. So how is this done? Also shouldn't I be able to drop the screen out once the oil cup is removed? Even if the air cleaner body is still on the tractor? Thanks. Vern
 
There's 3 or 4 small bolts that hold the assembly to the block and radiator clamps/hose that connect to the rigid pipe to the carb intake, then the breather tubing that connects it to the front engine cover. I think you're going to have to remove the complete assembly and wash it in a bucket of kerosene or diesel fuel. Probably easier tro do if you take the hood/fuel tank off too. I don't think the metal filter medium inside is readily removable. JMHO Stan

There are 2 bolts that hold the air cleaner onto the engine.
I remove the oil cup from the air cleaner, then use a 1/4" drive ratchet, and a 1/2" socket, and reach up under the air cleaner, the 2 bolts have to be removed.
I have the short air intake pipe, above the hood, and the air cleaner comes out from under the hood.
I don't know if the air cleaner with the long intake pipe comes out from under the hood.
You may need to remove the hood.
The filter material doesn't come out of the air cleaner, it is made together as a unit.

Clean the oil cup, and wash the cleaner out with solvent. Pour solvent into it, upside down, put the oil cup on it, cover the pipe for the tube that goes to the carburetor, and slosh it around, try to clean the material near the bottom of it too, then dump it into a clean pan, you can repeat that if needed.
If you use a clean pan, you can see what comes out of it.

Be sure to clean out the pipe down through the center of it. I use a long screwdriver, and put a piece of rag that will push through the pipe on the end of the screwdriver, and push it all the way through. Repeat that a few times, then wash it out with solvent.

Clean the oil cup too, it might have hard dirt in the bottom, dig it out until the metal is visible. Wash the oil cup too. Fill it to the fill mark with new motor oil. I use light weight oil.
Below is a picture from TM Tractor Parts of an air cleaner with the long intake pipe, showing the bracket and 2 bolt holes. :)

Below are pages from the 1950 Cub owner's manual on here telling how to clean the air cleaner.

The original air cleaner intake caps I have seen are made to fit tight on the top of the pipe.
To tighten it, put it in place, and hit it gently in the center, down, with a rubber hammer, that tightens it in the pipe. Just 1 hit.
If you don't tighten it, it would be sitting there loose, and could fall off.
If the paint is new or nice, be careful. Try folding up a clean rag, so it is thick, and put on top of the cap to hit on. :)
