Hydraulic Leak Under Tractor

[Breezely]

There is a very slight hydraulic leak under the mid-section bell-housing on my 2017 John Deere 3025E tractor. It is very difficult to determine where the origination of the leak is because of the nearly impossible access to the area of the leak under the tractor. Is it possible that there is a connector that can work it's way loose?

Have you crawled under the tractor to take a look and see where the leak is originating? Perhaps post some pictures. Very difficult for us to help diagnose over the internet without further details.

Yes, it is possible for connectors to allow a leak even if they haven't worked their way loose. With worm drive clamps and any screw-adjustable type clamp the steel clamp ring has no way to continue applying pressure to the hose as the hose end hardens, looses elasticity, and then takes on a compression set with age.

That is why worm drive and similar screw-adjustable hose clamps aren't as good as the spring type clamps that can maintain their spring pressure as the elasticity of the hose decreases over time.

Even if a connector like a worm drive type is tightened and the hose looks good, the common age-related hose failure is for the hose to longitudinal splits on the inner surface of the hose ends as they age. The splits are usually under the hose clamp area. These cracks are pretty much invisible when looking at the hose, because being at the end of the hose that type of split just shows as a pinhole. And it is complicated because many hoses are cut to length and so the ends aren't perfect to start.

The best evidence for that type of internal crackingis that there is hydaulic fluid on the outside of the hose but no clear reason why it got there. So clean off the hose and see it it accumulates fresh fluid on the OUTSIDE of the hose at a low spot. I use a pressure washer and soap solution. Another indication of an old hose leaking that way is that it will drip more when parked & not running than when it is running. That, and perhaps the hydraulics don't seem as responsive as they should.
