Ford Shop Manual (9N) and air cleaners

A few years ago a family member gave me a 9N so I bought a shop manual for it. (I am by profession a software developer which is to say I know nothing about tractors). I was looking at a troubleshooting section in the manual which makes two statements: 1) Check for a clogged air cleaner, and 2) Check for a plugged air filter, depending on the symptoms.


I can find the diagram for the air cleaner but nowhere can I find a reference to an air filter. Are they the same thing?
 
On older tractors, which the N series qualifies, there is not an air filter as in new tractors. It is more of and air cleaner. It cleans the air by use of an oil bath to collect the dirt then the air flows through a metal mesh filter in the canister above the oil bowl. That is what I believe the manual is referring too.

Thanks, Tony. I'll just go ahead and clean the air cleaner then. If that's not the problem, at least I'll have learned something about my tractor.
 
To clean the "air cleaner" normally you remove the oil cup on the bottom and dump out the oil, then
clean the dirt in the bottom out, refill with oil to the level, usually indicated by some marker on
the side of the cup. Sometimes though the metal mesh inside the cleaner needs to be cleaned too. It
can become plugged with dust, hay seed, dirt, etc. To do this usually you take the whole air
cleaner off and rinse it with gas, sometimes soaking for a while to dissolve the caked on dirt and
oil mud. This mesh can probably be removed, but it is seldom necessary unless it is rusted solid or
otherwise damaged. After cleaning and drying pour a little oil to moisten the mesh again and you
are done. I know using gas is dangerous, but that is what most farmers had and used and it works,
use a safer solvent if you want. Paint thinner maybe.

Thanks, 4wdtom. You probably saved me some time and frustration with your instructions. I do appreciate that.
 

special air filter oil??

No.. same oil that your running in the engine. just fill to level mark, and install cup... clean and service it every time you change engine oil. More in dusty conditions. run a good HD oil with the additive packages to protect the engine.

Well, got it back on. I was surprised at the sludge on the bottom of the cup. Had to have been an inch deep. I changed the plugs too. Can't wait to get the hood back on. I feel like a kid at Christmas. Thanks everyone.
