4115 power steering leak

4115 power steering leak update

Turns out to be a design flaw on the leaking connector on the metal oil tube that leads into the power steering pump. This tube does not have a ORB connector. The flare end seens to have cracked due to vibration. I have ordered the new parts and will post an update. I don't know which, if any other models in the 4000 ten series could have this problem. The new part that I ordered comes in a two part tube, one being a rubber hose. I did contact John Deere since I saw that the 2520, which is simular to the 4115, had a design change in this area which makes me believe they knew there was a problem. This is just my opinion. Thanks Larry

Glad you found the problem...Never heard of it before so I don't necessarily believe the "design flaw" statement. Please post some pictures if you can.

Kennyd, I have no pictures but I can tell you my opinion. I hoped you were right with it being ORB tube connector that way maybe I could just replace the o ring. When I took it off I saw no o ring just metal to metal (flare to nipple). I could not realize how this could leak except from wear. When I looked up the part on JD parts I saw they had a sub part, which is now a two part system. Just for farts and giggles I looked up the same parts on the 2520 which was redsigned so I figured there must have been an issue. As luck would have it or not have it, I called my local JD dealer to order the new parts. It turned out that they have a 4115 in the shop with the same problem. The parts man, which has so much knowledge its scary, told me it appears the vibration from the solid end to the solid end cracks the flare end. This is only the second time he has heard of it. It seems that time takes it toll. So I asked him about the other solid metal tube that runs from the power steering pump to the oil cooler and he said it should be ok because it runs into a piece of rubber tubing which absorbs the vibration. I hope this helps you to understand my opinion, I'am not an engineer but just put two and two together. Larry
