I really couldn't decide what forum, to post this on, and tractor talk , seemed to be as appropriate as any listed. That said,, - my problem is that my lift cylinders, will very slowly drift down when they were supposed to be holding a load. A little history will now be given: This winter the loader would drop, seven to eight inches when I touched the control to go up. Not knowing diddley about hydraulics, I decided to have the giesen control valves rebuilt. I carried the valves into South Sound Hydraulics, and left them to be rebuilt, I then went home and drained all the milky oil, out of the resivour, hoses, and collapsed the two cylinders, to get any old oil from them. I refilled the system, with wally world Hy Tran oil. When I got my control valves back, I topped off the system, and raised the loader, to get all the air out, and the loader continued to have that big drop, when starting to raise it. I then decided it must be faulty lift cylinders. I removed the lift cylinders and carried them into Epic Industries, on the Tacoma tide flats, and left them to be rebuilt. When I got my rebuilt cylinders back, I installed them, and again topped off the oil, went thru the same raising and lowering act, to remove any air, and no longer had the dropping problem. I WAS HAPPY, I have been using it all winter, to feed big round bales with and felt good about it. Yesterday I used the loader to suspend, my ground driven manure spreader, so the wheels were about a foot off the ground. shut the engine off, and began working on the spreader, and within an hour, the spreader wheels were on the ground, a very slow down drift. Now I gave you guys all pertinate info, that I can think of, and hope someone, can tell me if the control valve rebuilder screwed up, or was it the lift cylinder rebuilder? Why is my loader bucket drifting down?
