I am in need of some help please. I have searched, read a lot, found a lot of suggestions, so far I'm having no luck.
Yesterday I was using my 7000 Maroon Belly running my rock picker. When I dumped what turned out to be the last load, I lost all hydraulics. I have no steering, no remotes, no lift arms. The clutch and power director work. Up until this point everything has been working great.
What I have tried/checked is;
The clamps on the bottom of the pump were and are tight.
It also had puked some oil out of the shifter at the same time it stopped working. At first I was thinking possibly it got hot so I shut it down and went to lunch. After lunch I checked the oil level. It was sunny, it was hard to see the exact level (I'm not a fan of the sight glass method, I'd much prefer a dip stick), but it was low. I added some fluid and again, with the sun, I did over fill it slightly. I started it back up, no change.
Next I took the line marked with the red arrow off and the pump was full, no need to add any oil there. Then I took off the metal line, filled up the pump and started the tractor - nothing.
Next, with the tractor running I cracked the 3 lines marked with arrows and got the following results;
From the red arrow line I got nothing, and I mean nothing. Once I checked the fitting this line felt like I could have completely removed and replaced it by hand.
From the line marked by the blue arrow I got a nice steady flow of clean, clear oil.
From the line marked with the white arrow I got a mess, as shown below. This line spit a steady flow of oil with seemingly a lot of air mixed in. Obviously it's foamy but there I'm also due for an oil change so there is also some moisture in it. Not THAT much, but some. The air mixed in seemed to get a little better but it never completely turned into a nice steady flow like the blue line. You can see it spitting in the picture below.
It also puked a little more out of the shifter, although not much.
It was getting late in the day, rain was in forecast, and the tractor is stuck in the field, so I didn't take the pump off to do any further investigating. The rain came, so I figured I'd ask here to see what else I should try before digging in any deeper.
Any advice, ideas, or words of wisdom are certainly appreciated.
