FEL cylinder leak

[JPB7745]

My dealer filed for a warranty claim but tractor FEL was 8 months out of warranty. This is a defective weld weld that drips when a heavy load is lifted. I guess I will remove cylinder and weld it myself.

Just grind it a little bit to get fresh metal and give it a tack weld of the pin hole.

Looks like it's in the back of the cylinder, so you may be able to just extend the cylinder and weld in place.

Just what I was thinking too!! Thanks

Be sure and video it when it blows up.

Why would it blow up?

You need to get the oil out of the crack if you expect to weld it successfully.

Yes I do agree, plan on disconnecting hoses, grinding down a bit and heating up that area with torch to burn off any oil that may be there. Good point.

Im curious too. Like did kubota start using gasoline for hydraulic fluid or something?

That is so obviously a manufacturing defect I'm surprised Kubota won't cover it. You might try contacting kubota yourself and see if they'll help you.

Yeah, you must cook the oil out of the crack first. Then, after welding, do an air test with soapy water to test for leaks. If you don't air test, and you have some more oil leaks, you will have to cook the oil out again. Sometimes, you have to do several air tests and welds. I have done this more than a dozen times. Welding hates oil.

For my air pressure test, I just stick a rubber-tipped air nozzle into the work port with the rod fully extended. I have had pinhole leaks numerous times.

He's 20 months into a 12 month warranty. I'm not surprised.

You could fix it yourself for less effort than attempting to get someone else to do it. And you’re only out at most a can of Kubota paint. It’s not like it’s going to cost big bucks.

It’s not going to blow up. Melting the seals would be the biggest risk but since it’s not the gland end that’s not going to happen either.

I wrote Kubota customer service a long letter explaining the whole issue and they just passed it off back to local dealer. Just coming to fix it myself.

If you get a chance to take a picture after you grind/drill that area out, I'd be curious to see what the fault was. It kind of looks like they left a bit of slag at the point where they finished the weld. That might explain why it took so long to start leaking, the slag held for awhile.
