Fast hitch cylinder - raises and lowers with nothing attached. When I put a 7-ft back blade on, it may not lift at all or it might partially lift. Generally, it will raise a 4 or 5 inches and then stop. I found this while grading a driveway last week. After parking it, I also noticed oil slowly dripping from the cylinder (hoses are new).
Behlen power steering It steers fine in either direction and there are no noises that I would associate with the unit. I know the return hose needs to be replaced and the output shaft seals are leaking enough to leave oil on the valve cover.
Earlier this year I drained the hydraulic system and replaced it the fluids with Hytran. The filter screen was checked and looked nearly new. I cycled valves and steering multiple times to circulate the new fluid into the system. I found that even then it appeared to have air and/or water (discolored and foamy). When it is not running the oil is correct color. I ve opened the drain plug slightly to remove any water that might be in the bottom of reservoir. No obvious sign in the -1 cup of oil I took out.
I have not used the tractor other than to move it in and out of the barn a couple of occasions until grading the driveway. Yesterday I found that the reservoir needed nearly a gallon of Hytran to fill it. The engine oil level is good (not making oil) so assume the pump (M&W 201PX) seal is good.
My questions:
1) Would the leaks on either of these units draw enough air to discolor the oil under operation?
2) I have ordered a seal kit for the fast hitch cylinder, but wondered if the power steering output seal could be replaced without tearing the unit down?
3) Can the fast hitch cylinder leak enough (bypass internally) so that it would not be able to lift under load?
Thanks in advance
