4115 power steering leak

[Newtogreen]

I just notice where fluid leaked on the mower deck after my wife mowed last week. All I could see is fluid on the power steering hoses apparently coming from the top where the steering colume is housed. Not having time right now to take the plastic cover off what are the hoses leading to and how hard is removing the plastic cover. Any ideas what could cause a leak now the tractor is a 2005 4115. Any help or ideas are welcomed. As always thanks again. Larry

The hoses go to the steering (orbital) valve, #19. I have never removed the cover on my on 4110 (same as your 4115) so I cannot advise there...

As to what caused the leak? No guesses at this point-not enough info.

Thanks for the reply, maybe someone has taken this panel off and will explain the procedure. Larry

I have the 4110/4115 tech manual and this is what it directs you to do. Hope this helps. -Jeff

power steering leak on compact JD

I have a 4115 JD which is simular to a 2520 compact tractor. I noticed fluid leaking on the mower deck and also saw fluid on the hoses going to the power steering pump. I took off the pastic panel surrounding the sterring column and saw where the leak is coming from. There are two tubes coming from the pump and two hoses coming from the pump. The leak is coming from the bottom tube which is very hard to get to. I quess I have to remove all of the tubes and hoses to get to this tube. I don't know what kind of fitting is on the solid tube. Should I just try to tighten the fitting or unscrew it and see what the problem is. I don't know at this point if there is an o-ring or not. The tractor in five years old without any leaks so far. Any help or useful information would be helpful. Thanks Larry

Thanks for the useful information I figured it out. Now if I can only figure out how to get to the bottom tube leading into the power steering pump. The leak is in the fitting and I hope it just needs to be tighten. Larry

Re: power sterring leak on compact JD

How many different threads are you going to start about this?

Re: power sterring leak on compact JD

The more the better I quess. Since the first post was before I got the plastic panel off and now that I have found the leak I figured the hydraulic section would be the place to go. I assume that since you never had the plastic panel off you never had to deal with the power steering pump. Do you have any knowledge about the tubing JD uses and the connectors that lead into the power steering pump? I quess not many people have had this problem with the lack of replys even though I did not give or have much information to offer. Thanks Larry

The problem with this way of thinking is that any information (like the diagrams I posted, and the instructions for dash removal) are spread acrossed multiple post's. So other people don't know whats been suggested or offer advise that already been suggested-or they don't know any updates from you. Keeping everything together is best for you and others that are trying to help you.

Now, the hardlines should have ORB (O-Ring Boss) fittings on the ends, so yes there is a O-ring and it's possible it's just loose, or the O-ring is bad.

Re: power sterring leak on compact JD

Some people stay on their favorite forums and the threads were different but I get what your saying. Thanks for the information you have alot of knowledge, I think I will just contact you.:thumbsup: I will also get a tech manual in the future. Thanks again Larry

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
