Something went wrong after Hyd oil change.

Is there a sight glass or dipstick? How do you determine the level is correct?

All these tractors are a bit different, but surely there is a "full" or "low" level indicator of some kind?

I'm waiting on the filters now. I put the original ones back on. The part that has me stumped is before when I was on a hill and put the clutch in it would free roll, Now it holds pressure and sounds like it's spinning the gears backwards. There was also pressure still in the big suction filter as oil kept coming out of it when I removed the filter. I know hydaulic fluid won't hold pressure but air will. It they are self bleeding then I don't see how it can get air pressure built up.

It's a dip stick.

Photos might be helpful.

In any case, if the fluid was put back into the proper opening(s) as some tractors have more than one, then this surely sounds like a vent plugged somewhere. Just not familiar enough with this tractor. Do you have or can you find online some schematics of the system? Sometimes parts blow up drawings are very helpful. These call out various parts and can help identify something for you to have an Ah Ha!! moment.

I looked all over, the only thing I can think is there is air trapped in the highest part which is the oil cooler. This would kinda explain why it was pushing fluid out of it while it was parked with the oil filter off.

Go back with MF oils! I had a MF596 in my shop doing a hyd oil and filter change and my guy put a off brand oil in it (which stated was for MF tractors) and the lift and the brakes would not work. Had to drain it and go back with MF brand oil and never had any other trouble out of it.

I personally do not believe that the filters you put on are causing this problem, nor the oil for that matter. The aftermarket oil and filters may not be of premium quality comapred to the dealers brand, but in new condition should work fine. I think you have a seperate problem that came along at this worst of moments, that confuse what is going on.

The only thing that baffles me is it worked fine before the oil change. That and the oil kept flowing out of the filter housing. It make me think that there was pressure somewhere. If the system wasn't venting I could see it or air bubble. I just ordered a Manual.

OK. Take this for what its worth, which likely isn't much. I am NOT an expert in anything mechanical. I know where the fuel goes in, and I can change the fluids, but I don't know much more than that.

To the point, I overheard a couple of gear-heads talking filters a few weeks ago. The details are a bit sketchy, because I only partially understand what they were talking about. The gist of the conversation was something along the lines of some generic filters being crap, and the filter's innards are actually sucked out and into the system, doing whatever it is a sucked out innard would do to a machine.

I don't know if that's even possible, but that's what I got out of it...:confused3:

Yep, that passed through my mind too so I cut the outer shell off the new filter. Everything was still there. If I saw something missing i'd prolly sell the Front loader and backhoe off of it..
