2520 tractor hydraulic leak

[smalltown]

My new 2520 has been running ok for 8 days. Today while backing up I thought I was seeing smoke and my heart sank. I aslo noticed wet leaves and realized I must be leaking something. I immediately stopped and saw what I beleived was hydraulic fluid dripping from one of the power steering hoses. I started the tractor and thought if I turned the steering I would be able to identify which hose was the culprit. To my surprise it was leaking not from either hose, but from the bottom of this unit I have yet to identify.
There is a spray coming out of a pin hole leak on the pipe very close to where it is welded to some sort of round metal cover with three screws that I can feel (with the tractor off). I imagine the smoke was the fluid somehow hitting the hot engine or exhaust ?

My dealer is closed for the day so I will call in the AM, but I would like to be able to intellingetly tell him what the problem is.

I have added two photos the first shows most of the unit located on the left side of the tractor below the alternator, and the second photo shows the very bottom of the unit and a yellow arrrow from where I judge the spray to be coming from. The metal hose attaches via a weld to a round cover held on by three screws. Is this unit one of my two hydraulic pumps?

This must be a warranty item. I hope the dealer agrees and either sends out somebody to replace the cover and metal line on site or pickus up the tractor for a shop repair. Do they work on hydraulic lines in the field?

Hey smalltown
Sorry to hear about this problem you have.
I just went and looked at mine,and that line runs all the way back to the transmission.So it could be the pump that drives the hydro,not certain.
I tried looking at it on JD Parts site,but it's fairly vague.

They probably damaged it installing something on the tractor at the dealer.

In general, it sounds like a poor welding job. If the dealer is not to far and it is under warranty, take it in to the service center and let them fix it. If the dealer is far away, You could probably fix it, but they would have to see the leak, and with the part off, they might not agree. Maybe if you made a video, they might just give you the part.

Why are those loader mount bolts painted green? That is a dealer installed item..

 

[smalltown]

As far as being painted green that's the way it was delivered.
Anybody know what that unit is?

glc24 not to unhappy it's been running great. As long as the dealer does right by me I will have nothing to complain about. Things happen

When the problem first occurred there was a real strong smell must have been burning hydro fluid on the engine or exhaust and it smelled a lot like cat pee!

It's the engine mounted hydraulic pump that supplies pressure to the implements. The transmission has it's own pump that provides the charge pressure and operates the 3PH and PTO clutch.

Thanks Doug. I called this AM and talked to the service manager. John Deere will cover this under warranty, but not pay for transport. So today or tomorrow I will see if I can locate somebody to help me load.
Sounds like this particular metal line is not normally in stock and might require ordering.

Still a very happy camper, just need to get over the hump!

That is your hydraulic pump, the pipe on the top with the rubber hose is the suction side of the pump, the line you stated that leaks is the pressure side or outlet. Not really a big fix.
