I've been plenty busy with my 2720 this summer doing some rough work overall, and noticed a wet area under the rear banjo that seems to be emanating from the bottom of the rear filter cover.
I checked the tightness of the filter casing bolts and they seem tight. I've kept watching it over the past couple of months and it appears to have increased slightly.

The obvious fix seems to be to remove the cover and install new o ring seals. However the more I ponder this, I am thinking that if I remove the cover there will be significant hydraulic fluid loss..or worse.

Has anyone else had this problem and how have you fixed it? I could simply drive the tractor a little over a mile to the big dealer and have them diagnose and fix the problem, but I am reluctant to turn it loose given my past history with them.
Thanks for any thoughts.

Can you please get me a picture of the offending fitting and plate?

I think this is what he is talking about. :unknown: And yes Verdeo, you'll have to drain the oil. You should be able to get it fixed under warrenty.

Yes, that's it Randy. Towards the bottom of that attachment is a exploded picture of the filter screen with the magnetic inserts. The cover for this on the housing is where I think my problem is.
That O-Ring seal must have failed as it appears that oil is slowly seeping from the bottom of that cover and coating the whole underside of the rear axle with fluid.
Since everything is black under there...it is difficult to pinpoint exactly where the seepage is. I have wiped the area off several times but still can't see clearly.

The wetness begins at the bottom of that cover.

You mention warranty....I am wondering if JD will honor that if I was the one to change the fluid last fall.

Thanks for the advice and suggestions, Randy!

They cannot dis-honor a warranty because you do your own service.

Well, that might be a tough one though, maybe a new o-ring at the very least. They will claim you damaged the seal, to which you may or may not have. My dealer gave me a piece of advise when doing this exact service, "always use an new o-ring when removing the cover". I took his advise and bought several just to have on hand. :thumbup1gif:

My sincere thanks to Randy and Kenny.

I did not install a new o-ring when I changed the fluid last year. I did take great pains to handle it carefully and gently cleaned it before I re-installed it. But your points are understood. If I were a dealer, I would suspect the process.

I think I will bite the bullet and drive it over there and see what kind of reception I get. I have no problem paying for the service ...I don't need the abuse or dis interest that I usually endure.
The main point...I'm hoping that the o-ring is the issue and it can be quickly repaired.

Again, I appreciate the thoughts and comments you folks have shared here!

For general information

Mine just stated leaking there as well. 40 hours on machine never been serviced. leak is minimal...just enough to make it look like a wet spot on the draw bar but not enough to run on the floor. Just thought I would let ya'll know in case this become a pattern...
