tire - valve stem leak

[Wingnut]

I just finished doing some bush-hoggin' and heard an unpleasant sound when I turned my L3710 off ... a wet bubbling hissing.
I checked and one of the back tires (filled with Calcium Chloride) is bubbling abay from the top of the valve stem.
- do they usually just fill the tire, or put in a tube and fill that?
- is there any way to replace a valve stem without taking off the tire, siphoning off the fluid, fixing the problem and replacing the fluid?

too bad that common sense ain't

Wingnut, first of all, I guess you know that calcium chloride is highly corrosive, and parked where what leaks out won't do too much damage. It will sure kill any vegetation it gets on. Secondly, I've never heard of putting it in a tubeless tire because it will corrode the wheel. It's supposed to be in a tube type tire. And thirdly, you say it's bubbling at the "top" of the valve stem? Does the valve core simply need to be tightened? If it's leaking from around the valve stem, I'd say you're going to have to break it down, patch a tube, etc./w3tcompact/icons/frown.gif Good luck.

Wingnut,

You must have listed your tractor model wrong! Wen and Bird said that Kubota's NEVER need anything, NOTHING, NADA!!

It must be Blue or Green or Yellow or White or Red or ?

JimBinMI

The world without Blue would be too Orange!

 

[Wingnut]

Jim ... nothing wrong with the Orange at all ... it's the danged black thing that keeps it off the gound that's crying!

That's about what I feared, Bird ... I've got a bucket trying to catch most of it now ... not sure why it's weeping so much since prior posts had mentioned 70% - 80% full ... and I made sure that the stem was at the very top when I stopped. Fortunately, what is running out of the garage is going down the paved drive and into the ditch where it can kill all the reeds it wants to! I just hate to see money leaking away like that.
I tried tightening the stem but I'm afraid if I tighten it any more, it'll break .... and that would really suck!
Can't and why it would start leaking ... was just cutting grass at the end (had zapped all the sucker willows earlier in the day.

Dang, that was dumb, wasn't it ... answering both of you in one post ... ner get to be a STAR that way ... bwahahahahaha

too bad that common sense ain't

JimBinMi, I said the Kubota doesn't need any repairs; didn't say anything about the tires (mine are Goodyear on the front and Firestone on the rear), and I ripped a valve stem right out of one of my front ones pushing a big pile of brush awhile back./w3tcompact/icons/wink.gif

Hi ya Wingnut
seeing i don't know what bush-hoggin is (word not used in New Zealand) but if it's moveing or choping bush ya may have got the valve stem hit but a stick and pinched it on the rim ..ya can stop it from happening again if thats what happened by tack welding a bit of 1 1/2 -2 inch pipe abit longer than the valve around the valve stem (some even put screw on tops on too) i have seen skidders in the logging game rip the valve stem clean off ..the idea might help ya

Wingnut, you have my sympathy, but I'm afraid that's about all I can do for you. You're just going to have to have that one broke down and fixed, or do it yourself if you know how; not a fun job.

Far as I know, there's always a tube in a liquid filled tire. From the post, it's not clear if it's the valve stem that's damaged or the valve core that's in the stem. If liquid is leaking out the top of an apparently undamaged valve stem, I guess you've tried replacing the valve core.

 

[Rowski]

You may what to jack up the wheel that's leaking so the fluid doesn't get pushed out as the tire goes flat.

Actually, TomG, there usually isn't a tube in tractor tires, whether they're hydroinflated or not. Some people use tubes if they want to use calcium chloride for ballast to get the extra weight so the stuff doesn't eat up the rims. Sometimes, too, a tire will get a bad puncture and they'll patch the tire from the inside to keep debris out, then put in a tube to hold air. But otherwise, tubes are the exception rather than the norm.

Back back a bit there mark .. tractor tires being tubeless, yes some are now (last 2-3 years)but cross ply and 12-14 ply wire tires have tubes in them .ok smaller tractors yes ya maybe right but i think around 60hp +ya will find most are running tubes from day one (maybe cos the builders of them know most will be filled)

My M6800 (68HP) is tubeless. They are filled with over 500# per tire of water/antifreeze (non-toxic type). They wanted $40 USD labor per tire plus about $20 USD for the tubes if I wanted them installed. How is everything on the other side of the world. Summer about here in Texas - 100 degrees predicted this week. /w3tcompact/icons/smile.gif

I've got two old rear rims torched into quarters just to get them off the tires. The tires were all that was good. They had been toobed and filled with CalChl. They had a rusted hole big enough to push a punkn' thru around the valve stems. $90 for new and $70 for used 24". I'd a let you have the Calcium Chloride, but it killed some weeds.

You play with them wet and you pay for them wet./w3tcompact/icons/frown.gif

Sorry for the misspelled Toobed!!! Jamie's looking over my shoulder and is correcting me. I SHOULD have typed "TUBED". I know they are not tubs. But if 80085 don't spell *****, I'll eat my hat. Pass the Calcium Chloride, please. It must be getting late. /w3tcompact/icons/laugh.gif

Hi ya Wen..maybe i spoke to soon about tubeless but as ya say ya it has non-toxic filling in ya tires so rust is not a prob with running tubeless ...as for the "OTHER SIDE" we are going in to winter but could do with more rain ,only other prob is fuel (gas)has gone up again to about (nzd)$1.10per liter (usa workings) about $2.47 per gal ..i just got to ask why the hell do ya want anti-freeze in 100 degrees, how cold do ya get there ??? we get down to about 14 dF only then would we add antifreeze

Thanks. I had a wrong impression i guess. I do recall people talking about 75% fill going over the top of the rim to lessen corrosion. Guess that does imply tubeless tires. If there are corrosion problems on the rims using CACL fill with tubeless tires, I guess tubes eliminate it. If so, there must be some real disadvantage to using tubes.

 

[Bird]

Mark, I've long had a preference for tubeless tires on everything (and radials, of course), but are you sure about tractors "usually" not having tubes. All the farmer friends I have around here have tubes in their tires. I never asked my dealer about my B2710, so I don't know for sure that the R1s I have are the "standard" tires for it; I just bought it as it was, on the dealer's lot, but it came with Goodyear tubeless on the front and Firestone tube type on the rear. When I first noticed it, I was puzzled by that, but then assumed that maybe it was because the manual talks about putting calcium chloride in the rear tires for ballast and says to not put ballast in the front tires.

A neighbor just told a couple of days ago that he had to buy new wheels (used wheels) last week for the old Oliver he's had for 4 years. He bought it from a dealer here in Texas, but it came from up north and had calcium chloride in the tires when he bought it. Now it had rusted out the valve stem holes too big to keep using those rims.

[Wingnut]

hey guys, thanks for all the great advice. I guess I should have been more specific ... the leak was at the "bottom" (tube end) rather than the top ... yes, I would have replaced the core if it had been dripping from there.
And I eventually figured out that if I got the pressure off the tire, it would stop leaking at the pressure stabilized (sometimes things are logical to me right away ... sometimes the lightbulb goes on after I get a good nights sleep, wander out to the garage and say "where'd that water come from").
I found out my 1/2" impact will only affect one in 6 nuts ... that a 1/2" socket bar and a 4 foot persuader work, ... and that a L3710 is da**ed heavy!! Since I haven't gotten around to building an a-frame chain hoist stand (on rollers) yet ... it was a good thing that I'd bought one of them 2 ton rolling shop cranes in a moment of weakness! (Otherwise I'd have had to remount the wheel and trailer the tractor to the dealers!
Looks like a pinched tube (poorly installed) ... but it'll take a day for them to get it done and let me know. I had a whole 21-1/2 hours on that puppy ... thank I'll get out the welder and mount those guards on the rim!
I'll let y'all know how it turns out!

I dunno - could be a regional thing, I guess. I know years ago, they were all tubeless, but almost none of the farmers I know use tubes, unless they're using calcium chloride, which is rare. Of course, they all run radials, too, so maybe that's the distinction.

My Michelin XM27 11LR16 front tires just came in today. I'm hoping I'll be able to get them mounted tomorrow. I'm anxious to try them out. /w3tcompact/icons/smile.gif
