A warm body that works for me part-time got on my 5600 and moved it. Later he told me he couldn't get the lift to go down. It has a post driver mounted on it. My tractor has a FEL and post driver mounted. I have one side of the remote plumbed in a loop so I can use both devices. With the hydraulic control lever under the seat pulled back, flow goes out to the driver when it's not operating it passes straight though, then goes to the FEL joystick and passes straight through and back to a port in the driver that returns it to a case drain to the tractor. This works fine. I found the hydraulic oil full of a LOT of water. I'm guessing the gear shift seal caused this.
I've drained and flushed it pretty much. I need to do it again soon, but I have plenty of pressure. The problem is the lift will not lower. The lever will move and it appears the lever is moving the rod that goes inside the body. Here's where it get strange. I noticed when I move the lever for flow under the seat to the neutral position, this normally puts the hydraulics back to the tractor and not the driver and FEL, the engine loads and it sounds like I've overloaded the hydraulics like a relief valve has opened. I've tried letting it sit for two weeks and seeing if it leaks down, it came down a little but not much. I've tried bouncing it by stopping the driver at 1/2 stroke, I even took my G/F's 383 MF with a FEL and pulling it down, no go. The other lever beside the lift lever, I think it's for draft control, makes no difference.
How does the lift hydraulics work? Is it possible the warm body pulled up and the lever was seized and he sheared something coming up or down? What has me stumped is moving the lever under the seat to put the hydraulics back to the tractor causes the hydraulics to load up. It sounds just like I'm trying to lift too much with the lift and relief valve is opening.
I hate to pull the whole top off that the lever is mounted on as have no idea what can of worms I'm opening when I do that.
A hydraulic flow diagram or anything that tells me how the flow goes would be helpful. I do not have a HP gauge, but I can probably get one next week sometime. Then I'd need to know what ports if any to test at to see what I have where.
