B6000 Air Breather

[KuB6000]

I disassembled my air breather tonight to change the oil in it. While assembling it, I realized that the air breather does not make sense to me. In my opinion, it does not force the dirty air to go through the oil. The dirty air is free to go into the engine. I've attached a schematic of what I think can happen.

Several questions:
1) Is the black, conical, steel cup supposed to touch the dirty air intake tube?
2) Is the black conical, steel cup supposed to touch the perforated screen with foam?

In my case, the answer to question 1 is definitely not. The answer to question 2 is that it is close. Perhaps an 1/8" to 1/4" away.

More questions:
3) The manual mentions to fill with oil up to the indicated level. I can find no mark to indicate how high to fill with oil. There was about 1" in the bottom of the plastic cup when I took possession of it.

4) Does the perforated metal screen with foam come out? If so, how do you remove? Fortunately, this foam appears to be saturated with oil, and I suspect this has been preventing most of the dirt from entering the engine. If it can't be removed, I imagine I will soak the whole assembly in gasoline.

5) In the parts manual, it mentions Item 20, Part No 10283-11210. I'm not certain I have that piece. It may be wedged up there with the metal screen I can't remove. I've also noted the plastic bowl doesn't seem to quite "mate up" with the metal parts as well as I would expect. It's close - but I'm wonder if perhaps this part got exchanged with the wrong part.

I have attached a couple pictures of my assembly in hopes that you will spot something I don't.

Thank you,
Chris

KU, I heading down the exact same road you are, one of discovery of a new (to me) B6000.

I believe, the air filter works by making the air take a really sharp 180 degree turn. Particulates in the air can't make the turn and end up hitting the oil surface and sticking. The oil soaked screen catches the rest.

ChrisB6000, Right you are!

[KuB6000]

Thank you! That makes more sense. I would have never thought of that.

That brings up two more questions:

1) How much oil do I put in the bottom of the plastic cup? I assume I want enough that there is a 1/4" of it in the bottom of the black, conical, metal cup so there is oil for the air to impinge on? When I took it apart, the oil level was below the metal cup.

2) Do you ever clean the metal/foam screen? If so, how? Based on the parts diagram, it doesn't appear to come apart.

Thank you,
Chris

Chris,

I took mine off the tractor and used a parts cleaner tank. Took a while of just flushing cleaner through it and smoe brushing to fully de-gunk it. A really good shot withthe air compresssor got rid of the rest.

The clear bowl originally came with a fill line. I could still see mine but I assume yours is non-readable. If I recall correctly when at the proper level there is about 1/4" of oil inside the black bowl.

Thank you,

I will give that a try!

I have a B6000 too, still don't understand how the system of the airfilter works.
The plastic cup should be filled with oil but the conical metal cup also need to be filled with oil, or needs to be just clean?

As far as i think is that the plastic cup needs to be filled with oil and the conical metal cup too? Is this the right way?
And which oil is be used for this, not too viscous oil he..

Thanks in advance.

It's okay, it are communicating cups, needs just to be filled both. They keep both in level.

The metal cup has 2 holes in the bottom, so oil will even out in the plastic bowel after you let it rest a minute. I'd say that you don't want to overfill the oil level, will cause it to leak out at the gasket when your running the engine, even pull it up into engine. If your 1/4" of oil is checked on the bench before you hang it on the canister, this will be the level in both the cup and the clear bowl. Should be good at this level.

I wouldn't use gas to clean the element (desiel maybe), could over fuel the engine with gas vapor on startup and bad things can happen if you do that.

I'll just let the dirt drain down on its own and take care of the bowl oil.

My air breather doesn't have the damper bowl (or any other of the parts for that matter aside from the plastic holder bowl and the screen/stack).

Any reason any of you can think of why I shouldn't fabricate one out of a metal bowl by drilling holes in it and placing that in there? New ones run $90.00. Likewise, are the other parts critical in any of your opinions?
