I'm a first time poster and first time tractor owner. I have searched up and down on the internet and this forum and couldn't find others with my same symptoms, and none of the proposed solutions for similar issues have worked for me. My maintenance experience up until now has been servicing my riding and zero turn lawn mowers. I'll detail out everything that happened and that I've done so far. Thanks in advance for any help!
I own a Massey Ferguson 2605H 4WD with a 911X front end loader. I bought this tractor new and operated it to the 50 hour mark doing bush hogging and loader work like moving rocks, cut up trees, etc. I have had zero issues with this tractor or the front end loader until I did the 50-hr maintenance. I am convinced that something I did--or failed to do--has caused this problem. From the manual, the major operations required to be performed at the first 50 hour maintenance are changing the engine oil and oil filter, the return oil filter (AGCO ACP0250270 - I have no idea what this is...is it part of the hydraulic system?), and the suction strainer (ACP0475810). These parts I identified between cross referencing the manual with the AGCO website, so it's possible I made an error, but when changing the filters out, the old ones looked identical to what I replaced them with, so I don't think incorrect parts are the issue. Changing the engine oil went fine other than someone at the factory tightened the oil filter tighter than I've ever seen. Changing the return oil filter went fine once I got the housing off. The manual was incorrect/old about how to do this. It listed bolts but instead the design now has 1-3/4 hex at the bottom to twist the housing out. This is shown in the first attached picture. I re-used the O-ring as it looked fine and replaced the filter, and tightened the housing back up.
Next I moved onto the suction strainer, and again found that the housing design didn't match what was pictured or described in the manual, so I had to guess at how to remove it. I removed the bolts on both sides, which drained about 5-6 gallons of hydraulic fluid, loosened the clamps on both sides, and then removed the 3 bolts at the top that mounted the housing to the tractor. I am wondering if I should have just loosened the clamp on the outlet end and only removed the bolts on this side? Anyway, I removed the whole housing, opened it up and replaced the filter. I am confident I placed the filter in the same direction as the previous one, then I put the housing back together and re-attached it to the tractor. This is shown in the second attached picture.
I replaced the hydraulic fluid with new fluid, filling up to the exact middle point on the dip stick between min and max.
I think the 3 point hitch and the front end loader work off of the same hydraulic system, but I'm not sure about the steering. The tractor started up and ran fine, but the front end loader was unresponsive. Oddly, one direction, curling down, worked for one tiny little bump and then it quit too, but all other directions (up, down, curl) didn't work at all. The bucket is resting on the ground, so I can't drive around and test the steering. I researched and asked around and was convinced that the problem was air in my hydraulic system, and most advice said that this will work itself out by exercising the hydraulics. I put about 250 pounds on the 3 point hitch, and the 3 point hitch worked just fine at raising and lowering. It did appear sluggish at first but after ten or so raises and lowering it was working just fine. I put one hour on the tractor, running it at about 1400 RPMs while raising and lowering the 3 point hitch and working the controls of the loader to try to work air out of the system. The whole time, the 3 point worked fine and the loader never responded. At this point I don't know what to do. I can't imagine working the air out would take this long, so there has to be something else wrong.
- Should I go ahead and fill up to max on the hydraulic fluid? I understand you can also have too much fluid, so I wanted to wait before trying this.
- Assuming the 3 point and the FEL are on the common system, what could possibly cause the 3 point to work while the FEL does not?
- what else should I try?
