The 3-point hitch and the remote hydraulics on my AC 5040 do not operate. The oil level in the transmission is at the correct level. The in-line oil filter (metal mesh) looks OK. I disconnected the hydraulic hose that goes from the fitting by the lever that operates the remote hydraulic to the quick connector at the rear of the tractor. When operating the lever some oil comes out at the fitting. However, the pressure is so low that I can press in the ball in the quick connector.

Any ideas on testing/repairing the hydraulic pump? I have the manual, but there is very little space to work on it. Is there likely to be some sort of obstruction in the oil line going to the rear of the tractor? Thanks

Be sure to eliminate the easiest and least expensive things first. It is common with these tractors for people to say that the filter screen looked good but when they tried it with the screen out, hydraulics were fine! And when they put a new one in, still fine. Might be worth a try and save you time and money. If it works with it out, just be sure to get a new one in it immediately or you'll be right back to time and money (pump, valves, etc.) If that doesn't work, read some of the many posts on this site about these tractors with this problem. Good advice there about (among other things) freeing up a check valve that sometimes sticks, bypassing the fluid back into the trans. instead of building pressure. Good luck!
