Tire valve replacement

[Gary S.]

Sorry it's not a Cub problem but with all the experience here I thought I'd better ask before I do something wrong. I am losing air between that plastic ? ring and the rim on my Ford with unfilled tires. Does it look like this is the kind of valve that unscrews from the tube? If so how do I go about doing that? Remove that plastic ring and then unscrew the valve? Or am I going to need to replace the whole tube? Thanks

if its coming from behind the plastic nut you have a leak in the tube itself, picked up a nail or something, would need to come apart, to be repaired or replaced, make sure to look and make sure whatever caused it is still not stuck in tire while its apart or you will be doing it again

Hi,
Do what Tim said, but to answer about the valve, the pic is a little blurry on my screen, but the upper part of the valve stem unscrews from the lower part, the lower part is where the round plastic nut is. The upper part is where the valve cap is, and the 1st part below the valve cap. It screws out of the lower part.

The upper part can be replaced, tire stores that repair tractor tires probably have new ones, and might sell you one.
There are 2 styles that I know of, the older style, and the newer style.
There might be nothing wrong with your valve, it doesn't look old in the pic.

Below is a pic of the older style valve, Cubs came with this style for years.
