B6000 Air Filter

[kdl]

I have a new to me B6000, which came with a damaged oil bath air filter. I don't believe it has all of the parts and I am confused by how its suppose to operate.

The tail end cylinder that comes off of the main filter housing does not extend far enough to sit in the oil, so im not understanding how the oil bath does anything to interact with the air?

I am also missing Kubota #10283-11440 DAMPER,AIR CLNR, which I also do not fully understand the purpose of?

If anyone has pictures of the complete air filter assembly, so as to help me understand?

I attached a PDF from K-Pad.
Check for the most recent part numbers any of your tractor parts HERE at K-Pad.

You can get the Owners Manual and Workshop Manual at kubotabooks.
Not sure how up to date the parts numbers are.

I am trying to figure out what item 21 is Kubota #10283-11440 DAMPER,AIR CLNR is and what its purpose is. I am missing it on my tractor.

Also, does anyone know if the small pipe opening is suppose to sit in the oil?

I don't have one so I'm only guessing, looks like #21 is a damper that is fixed to #19 with the wing nut and washer. Maybe to prevent the oil from splashing.

Can't see a "small pipe" in the diagram so I have no idea.

Are you missing #25 - instruction label?

The air must pass through the oil. So there must be some way to make that happen. To see this type of filter in action you can do a tabletop model. Easiest way is to get a clear plastic cup with a lid and a couple of straws. Put both straws through the lid but separate them by an inch or so. The bottom of one straw is lower than the fluid level (intake) the other is above the fluid level (suction).

Put some water in the cup to cover the tip of the bottom straw and be below the upper straw.

Tape the cup to be pretty air tight so all air must pass through the straws.

Suck on the upper straw and air will enter the cup through the other straw, bubble through the water and come into your mouth without carrying any of the water.

To see what the damper does, just tilt the cup back and forth and see how the water sloshes around. Then imagine a plate near the surface that covers most of the area above the water. Would the water sloshes around as much if there is a damper? (Answer is no). The damper is just to keep the oil where it should be while operating the tractor over uneven ground.

My confusion stems from this photo. The center "Straw" is where the air is pulled in through. It however does not sit in the oil, when filled to the "fill" line on the cup.

Did a search on how these work, here's what I found.

Air coming into the oil bath air cleaner's inlet is forced vertically down toward the oil reservoir. Once the air reaches the oil reservoir at the bottom, it changes direction rapidly and is then forced back up to the engine's intake system. It is the rapid change of direction in the air mass that cleans the air--while the air has no problem making such an abrupt change in direction, the sluggish dirt particles carried in it cannot change direction as quickly and end up being trapped in the oil reservoir.

That makes sense. It seems very passive and like it must not work as well as an air filter. Yet ive heard oil bath filters actually work better in dirty environments.

Can someone tell how soft is the packing part 20 in the exploded view? I was missing it from my kubota, and 3d printed it from 98A shore tpu, but it feels quite stiff for this and the bowl leaks some oil between the packing and bowl.

Disclaimer - I've never owned this type of filter and do not have any experience with 3D printing.
Not sure how to tell how "soft" it is but it's a rubber O-ring gasket.
If your printing with a 3D plastic it must be too hard to compress enough.

Yeah it's flexible to finger nail and bending, but not compressing as a whole.
I may try to 3d print a mould and "cast" the part with silicone and try that way. I tried to find the part on sale, but it's quite expensive to get it in Finland (over 30€) for what it is.
