Greetings!
I have a 2011 model 4120 ehydro that just developed a leak where the steel line that goes from the pump to the PTO valve meets the pump. Part number for the line LVA 12731.
Powertrain warranty still in effect, way I understand it the rest of the warranty went out at two years which would be at the end of March for me.
Before I head to the dealer I wanted to see if I had a quick fix warranty or not.
1. Visibly leaks when throttled up, about 1800 rpms or higher.
2. I figured great, vibrated loose and got it to tighten just a fraction, no change in leak.
3. Figured ok, blown or nicked oring. I replaced the oring part number T77932, no change in leak, old o ring under magnigying glass looked fine.
4. I am now thinking some kind of restriction is causing way high pressure, I don't know where the relief valve is in the route of things.
Background -
I put the 3rd EH valve on myself over a year ago. Had no problems with it. No leaks.
I put the 4th and 5th valve kit on recently, no leaks for maybe 7 or 8 hours engine use running a mower, no leaks. This I saw the leak after using the grapple and boxblade quite a bit this weekend. I cut down about 50 smallish trees to clear out a spot to put a camper on our hunting place used the blade to shape up a trail into a small road. Used the EH 3rd on the grapple and one of the levers (4&5) to run the tilt cylinder as well as the rockshaft a lot to run the blade. Noticed the leak while loading back on the trailer, next morning checked the hydro fluid and not down enough on stick to even notice.
Next steps and my questions -
1. I am going to check the screen in the fitting that goes back into the rockshaft valve.
2. Is there any way hydro oil can get into engine oil on this tractor? Call me crazy but I think the engine oil has gone up in level a little. Afraid to run it more to see if it rises.
2. ? Open to suggestions on what else to check.
3. How to I find out if there are any "TSB's" for lack of a better term.
Thanks in advance! I love this tractor and am a little bummed right now about this.
