L2500 Air Intake?

[Harv]

Bird -

About time I pulled this thread over here into <font color=orange>orange</font color=orange> territory. This is actually a reply to your last post in the "<font color=green>Check it out</font color=green>" thread.

Your air cleaner system looks identical to mine, except for the size, location, position, design and general layout. /w3tcompact/icons/laugh.gif

Now that I see the intake pipe that you're talking about, I think I can pretty safely say there ain't no such animal on my tractor. Of course, I can't pop the top off my engine compartment as easily as you apparently can, so I've just been peeking in from the sides so far. This weekend (I'm already counting the hours) I'll climb inside if I have to, just to settle this thing once and for all.

There's even the remote possibility that I might take a picture or two. /w3tcompact/icons/wink.gif

In the mean time, maybe some of our other 2500 owners know the answer. Rodneyd, Jeff_In_NC, Gerard, P.K.Burke, others? Where the heck is our air intake?

Hey, Harv, I'm like you - I don't even realize what forum I'm in /w3tcompact/icons/laugh.gif. If you hadn't said anything, I would never have noticed!

Omigosh, now you're pulling <font color=green>green</font color=green> folks over here, Harv. Gosh, this gets confusin'./w3tcompact/icons/laugh.gif

Harv, Bird & others... like the guy in the "Dirty Harry" movie says.... I just gots to know!

I feel like I'm following the yellow brick road...

Harv, when you "fill" up the orange forum... tell me you're not going over to blue and start over... are you?

Back to basics... What does an "air filter" do? Where is it located on your tractor? Take a deep breath... that "rubber nose", "dust unloader valve" and all the above with the slot is where the "air" starts coming in.

I don't bet... but I'll bet you a cold Pepsi that's it, Harv & Bird!

Well, John, it ain't worth arguing about, but that little flat rubber "evacuator valve" ain't big enough to let enough air in to run an engine. That's why it's got that other big air intake. I know manuals can have misprints, but I'm convinced Kubota is right this time about what it's for.

Golly, Fellers!

I'm getting conflicting input from intelligent, experienced tractor folks, none of whom give me any reason for doubt. And here I am in the middle, just bristling with ignorance. /w3tcompact/icons/crazy.gif

That evacuator/unloader/nose thingy certainly seems to me to be too small and built wrong for sucking air, but so far I don't see any other inlet, either.

Bird, my manuals "imply" that it's for letting dust out, but the only verbage I can find just says to keep it cleaned out. I now have the operator's manual, the parts list, and the workshop manual, but none of them really shed much light on this subject.

In fact, I've attached the excerpt from the operator's manual which is the only mention I can find on the subject. My new mega-dollar workshop manual has the exact same diagram and text -- a little disappointing. /w3tcompact/icons/frown.gif

I just sent an email to the only local Kubota mechanic I know to see if he can shed any light on this. I'm starting to think that 2500's just hold their breath. /w3tcompact/icons/wink.gif

<font color=red>Hey!!!</font color=red> I just looked at the attached diagram again and noticed something that could be a protuberance sticking out of the bottom of the filter canister. You don't suppose...?<P ID="edit"><FONT SIZE=-1>Edited by Harv on 02/01/01 03:33 AM (server time).</FONT></P>

Ok Bird & Harv...

Where do I send the Pepsi's to? Dum Dum Dum me.

Harv, You had fantastic pictures of the Front, the back, the side....

Except the BOTTOM! There it is... the big round opening under the air filter canister... the air intake!

Here's how my brand spanking new <font color=green> John Deere Tech. Manual </font color=green> explains the theory:

Air Intake System Theory of Operation:

Air enters through grille panels to air cleaner intake located in air cleaner housing. Air is then directed around primary element in a circular motion, throwing larger particles to the unloader valve. Air is then drawn through a secondary element through hose before entering the cylinder head.

An electronic air filter restriction indicator is located at air cleaner outlet to indicate clogged or restricted air cleaner elements. An indicator in dash will light when restricted.

An electric manifold heater (if equipped) warms intake air, by heating coils or metal strips as air passes through them, to aid in cold starting.

(a picture is shown in the manual, pointing at the various elements, showing a large round air intake opening at the bottom of the air canister {opposite end of unloader valve}) I'll try to scan the picture later today.

Excuse me now while I get all this "egg" off my entire face.

Harv, I think you're on to something there. Looks like an inlet on the bottom of the main canister. I was going to get real fancy and mark up your .gif but I'm not that talented apparently.

And here we go with the mixing colors again...

Good luck and keep counting those hours until the weekend /w3tcompact/icons/smile.gif

 

[markcg2000]

Is this right?

Mystery solved, Harv./w3tcompact/icons/wink.gif Now you can see in the intake on the bottom of the cannister. I do wonder if it doesn't have a hose or tube attached that leads to some place where it can suck relatively clean, cool air in.

And John, we don't have that indicator to tell us the air filter's dirty like you have, or the inlet air heater. I didn't know your tractor had those, but a neighbor's old (1972?) Oliver has both of them (and no glow plugs). I was really surprised the first time I saw that.

And don't worry about the egg; I've had it on my face a few times, too (too many times, in fact)./w3tcompact/icons/laugh.gif

Very good, Mark. Now someone else will wonder why his manual isn't labelled that way./w3tcompact/icons/wink.gif

I was thinking of trying to do the edits in <font color=orange>orange</font color=orange> but forgot; either that or it was a <font color=green>Freudian slip</font color=green> /w3tcompact/icons/laugh.gif!

[RobS]

This is why I love this board. There is always someone more talented than me that I can learn from. Now Mark, how did you do that?

 

[markcg2000]

1. Saved the file
2. Opened in Microsoft Photo Editor (junk, but all I have at work for GIF)
3. Didn't change anything, but did "Save As" with same name, but Window's BMP format.
4. Opened new file in Windows Bitmap editor and added the stuff. Save.
5. Opened the edited BMP file in Photo Editor and saved again in GIF format.
6. Posted. Simple, eh? (not! /w3tcompact/icons/wink.gif)

I've got Adobe Photo Deluxe (little brother of Adobe's high-end Photo Shop) at home, which will do the open, edit, and save in the same process.

Thanks, guys, for hanging in there on this one.

When you come right down to it, this was really an excercise in trivia, wasn't it? In fact, how did this get started? Oh, yeah -- I'm not supposed to pressure wash my air intake. /w3tcompact/icons/crazy.gif

Thanks, Mark, for modifying the diagram. I was going to do the same thing first thing this morning. Luckily for me, your morning arrives several hours ahead of mine. /w3tcompact/icons/smile.gif

<font color=blue>wonder why his manual isn't labelled that way.</font color=blue>

Good question, Bird. Up 'til now I thought the pictures and diagrams were reliable, and it was just the doubly translated text that fell short.

And John, don't whip out that washcloth just yet. We're all assuming the mystery is solved, but I'd hold off until I check it out in person. And if there's any egg dripping off cheekbones around here it has to be on me. I've had this diagram all along and didn't notice the unlabelled tumor on the bottom of the canister until just now. /w3tcompact/icons/blush.gif

The truth is out there, and I'll try to poke my finger in it this weekend. Unfortunately, since I still have no connectivity (or computer, for that matter) up at the property, I won't be able to post my findings until Monday. I hope y'all are able to get some sleep between now and then. /w3tcompact/icons/wink.gif

 

[RobS]

Is "Windows Bitmap editor " the same as MS-Paint? I tried something similar but Paint said the bitmap was too big.

Maybe I should get a life? I need some tractor time!!!!!!

Let's try this Air Intake Picture attachment...

Glad the mystery is solved Harv.

I'm trying to imagine this board if you, your computer, your digital camera and your tractor were all in the same place with a rural ISDN line /w3tcompact/icons/shocked.gif

It's hard enough keeping up now, that just puts my head into a spin /w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif

 

[JohnMillerIII]

What my John Deere looks like... sorry I don't have a digital camera guys... (yet..)

 

[Bird]

Good pictures, John, but you're doing just what I did when I first tried posting things from my scanner; GIANT pictures; need a 36" monitor (or a lot of scrolling)./w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif
