My job and the Kubota Dealership depend on your purchasing genuine Kubota parts forever.Grease fitting with ¼-28 male threads. You can get them anywhere.
Try backing the offending fitting out a bit and see if it will take grease.I took out the fitting that wouldn't let me grease the pin and it would let grease through it, but when I put it back in the pin it wouldn't. I took a fitting from a different pin and was able to grease the pin. To me that just doesn't made sense.
I could speculate about causes but if it were me I would just replace it.I have had the tractor since Dec 2014 and it took grease up till a couple of months ago. I had moved one of the fittings the last time I greased the FEL, didn't have the time to look into why it wasn't taking grease. I don't really understand why it doesn't when it is in the pin. I tried it in the pin that I took the other fitting out of and it does the same thing.
I could see it being a problem with it being too long if the grease path in the pin wasn't straight in.
My guess is the valve in the fitting is having an issue with back pressure but that is total speculation. In any event it ain't working and needs to be replaced.What's what my plans are, that is why I asked the question at the start of the thread. But I was just wondering if someone else had come across a fitting that has done the same.
