This site has been a great help to my 8N rebuild and it's almost done. Thanks for all the insight and info! Now I need advice on my last issue (for now).
My hydraulic lift leaks down overnight with a light load. It originally had a lot of condensation and the fluid was milky. When I tore it down to clean everything up, I found the lift cylinder scored and the pump pistons also had some scoring. There were a couple chipped pinion teeth, which probably contributed to scoring. I replaced the ring gear, pinion and bearings. I also replaced lift cylinder and piston (NAA o-ring style), pump pistons, bushings, valves and springs, as well as the safety valve. The oil is Travelers 90 weight mineral oil equivalent sold at tractor supply. The lift works perfectly otherwise and I'm sure both pressure tube gaskets are well sealed along with the lift cylinder port gasket. I have a wooden bed with stake sides that mounts on the 3 point hitch (less than 150 lbs. and only 4' long) that I want to stay fairly level for at least a few days. I have heard that when everything is right an 8N should hold a heavy implement up for a couple of days.
Any suggestions?
