Of all the things that I have done so far working on old ACs, messing with rear tire valve stems has not come up yet-until now. One rear tire (16.9x28) on my WD45 has started slowly leaking ballast from the valve stem. I have the valve rotated to the top to stop it for now. They haven't been touched in years which is why I'm thinking that my best plan would be to just get both rear valve stems replaced with new ones. My question would be is the valve stem assembly something that I could change out myself easy enough with just jacking the weight off the rear tire or MUST ALL the liquid ballast be pumped out of the tube before the valve stem assembly could be changed out with a new one?? TIA guys. ------------- "My name is Lionel and I'm an Allisoholic" |

Jack the rear wheel to get the weight off the tire and rotate the valve stem to the top and you should be able to change the valve stem w/o removing the ballast. However be very careful because if the stem part of the tube is corroded you could destroy it in trying to get the old stem off. Then you will be SOL and lose all your ballast plus having to replace the tube. ------------- Just an old country boy saved by the grace of God. |

Just jack it up and the valve at the top, with a pliers turn out the old valve and turn in the new one. I've done it without jacking it up but you gotta be quick if the tire is nearly full of fluid. Some real old tubes take a different valve that I don't think is available any longer, that's if memory serves me correctly. You should replace those valves every couple years or so. I write on the rim when it was changed last. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

Where is it leaking between stem and rim or out the end if it's between stem and rim tire needs to come apart to clean rim or next time you can replace rim and the tube ------------- You can wash the dirt off the body but you can’t wash the farmer out of the heart and soul |

If the tube isn't leaking, you can try twisting the valve core part out. I'd have an old, and new style fitting on hand, to make sure you have the right part to put back in. Gemplers ain't cheap, but usually have both styles...

We have replaced ours this year. They are only $3 or $4 each. Wish we had done so earlier. ------------- Dad always said," If you have one boy, you have a man. If you have two boys, you have two boys". "ALLIS EXPRESS" |

The valve stem might be fine. If fluid is leaking through the valve stem hole in the rim, chances are good that there is a leak in the tube somewhere. It is more work, but might be a good ideal to remove the tire and inspect and clean the fluid from the rim. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| If it is leaking out the valve itself, they make stainless steel core housings in the old and new style. I kept them both on hand. SS is usually a little higher priced than the machined brass, but worth it when you are messing with fluid. Where ever it is leaking it needs fixed asap. Might be best to call your local farm tire repair man. |

| Keep the old valve stem. You can replace the inside thing with the spring (don't know proper term for this) and use the valve stem again on the next one that starts leaking. I've done this half a dozen times, and works well. |

I did this the first time I replaced one in my WD rears, didn't realize the tire was so full of ballast and it sprayed out like nobody's business. Fortunately was able to get the new valve stem in, but there were 30 seconds of panic and swearing in the interim. |
