<font color=blue>keep water out of the air intake </font color=blue>

Time to embarrass myself again. /w3tcompact/icons/blush.gif

I've cleaned, changed and otherwise monkeyed with the air filter assembly, but I have yet to figure out how/where air gets into the system on my L2500.

If anybody's got an answer, you may have to talk real slo-o-o-o-w so I can follow you. /w3tcompact/icons/crazy.gif

Thanks for the heads up about the water. I plan on having the engine off and cool and I'll be real careful around the air intake, also around the fuel fill cus I think water under pressure can go back through the breather cap.

Thanks again

Harv,
Don't know if the Kubota is much different than the Deere as to the intake setup, but spraying really high pressure water around seams and joints on your air intake system isn't really a good idea. Seals designed to hold a couple pounds of negative vacuum pressure don't stand up well to between 1-2,000 lbs of positive water pressure. I just try to keep the spray head on my pressure washer away from some areas around the air cleaner system. An ounce of prevention is worth...

Branch -

I totally agree with your "ounce of prevention" approach, and I would definitely avoid pressure spraying around the air intake if I could figure out where it is. /w3tcompact/icons/crazy.gif

I guess I'll just do like you say, and stay away from the air cleaner system altogether.

Harv, I sure would like to see under the hood of your tractor; don't guess I ever looked under there on your model, but on mine, it's very obvious where the air intake is.

Don't underestimate my ability to not see the obvious. /w3tcompact/icons/crazy.gif

Actually, since this discussion began I've only been able to look for it in my manuals. When I get back to the property (this weekend?) I'll pop the covers and take a firsthand look. I just don't happen to recall seeing anything that looks like an intake when I was changing the filter.

I'm curious now -- on your tractor, where is the intake relative to your air filter? Also, where does it show up in your parts manual and what do they call it?

 

[Bird]

Harv, on my B2710, the manual calls it the "inlet hose" even though it's a rigid plastic piece, round on the end that attaches to the "air cleaner assembly body" (in other words the can the filter's in/w3tcompact/icons/smile.gif), and flattened on the other end. It runs from the filter can forward just across the top of the radiator with the front end turned down, so it's sucking in air from just in front of the radiator.

Okay, Bird -

Now I'm really scratching my head!

What's referred to as an "inlet hose" on my 2500 goes from the filter canister to, I think, the intake manifold (see #090 in the attached diagram). The only other thing that appears to be a gateway to the outside world is a doohickey called an "evacuator valve" (#046), which, from its name and design, appears to be a blower, not a sucker (technical terminology).

Coincidentally, I finally got my Workshop Manual today, so I checked out what it says about the air cleaner system. No mention or picture of an air intake (probably 'cuz it's so obvious /w3tcompact/icons/crazy.gif).

And, just to take this thread even further off course, my one and only local Kubota dealer/parts house is closing down for good -- tomorrow! /w3tcompact/icons/frown.gif It's actually called Farwest Equipment, and apparently the company has decided to close down all of its California stores. I hope this isn't a trend precipitated by the energy crisis and soaring cost of operation around here.

The only possible upside is that Kubota is said to want to maintain a presence in this area, so they'll be looking to open or contract another dealership of some sort real soon.

Omigod!!! I just realized this thread is in John Deere territory! Sorry for intrusion, fellas! /w3tcompact/icons/crazy.gif

Harv,

Put you hand under the rubber nose (046), at idle you'll feel it "snorting" more blowing than sucking... Crank up the rpm's to 2500... now you have a "vacuum cleaner"... if you could "smother" the air intake, you would "shut" the engine down...

On "our" John Deere's you remove the rubber nose and dump out any trapped dirt... Ok Mr. Kubota owner? /w3tcompact/icons/smile.gif
(yes, we also have to change air filter's etc.)

Harv, my 4100 has both, an air intake tube just as Bird described leading out over the radiator and that rubber nose /w3tcompact/icons/cool.gif is refered to in the manual as a dust unloading valve. It supposed to be cleaned as routine maintenance every 10 hrs. Also there is an Air Restriction Indicator thats part of the system to be checked every 10 hrs or daily that when visible requires immediate servicing of both the primary and secondary air filter elements. Gee, I hope your not feeling a little green from being over here. /w3tcompact/icons/smile.gif
