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
