hey guys, picked up mf 85 in the fall,finishing up 1st service. when i got tractor lift arms didnt work,owner said tractor sat for long time in the barn(years) but lift arms worked when it went in. power steering works perfect and pto works fine. when i lower and raise lever(for 3pt arms) i dont feel much tension or pressure,also i can manually lift the arms to full height and they also feel like there is no pressure behind them.
i have tried to do adjustment that are in the book w/ no luck. it feels like the pump is just not pushing fluid. i will post a picture tomorrow,but when you look down at the pump there does seem to be alot of turbulence around the piston area. i can see the actuator moving the piston left and right. i only have about 7 gallons of the 11 in,but unit didnt work prior w/ full fluids, original fluids where very milky which were flushed and then replaced again. when i drained the front plug off of p.s. brain i got pure water out for a bit then fluids. but again all power steering is working fine. seems like very hard to service pump in tractor does it have to be split to service? thanks for input.
