The pin looks good. We reassembled the valves and piston, put the cover back on and this time a celebration was in order. Although we replaced a number of O rings, none were in bad shape shape so I think your diagnosis of something going on with the unloader valve was the right call... -

The amount of spool travel is not important. the check the piston we blew air into the gallery where the oil enters the lift cover which I believe is the forward hole. The spool and snap ring look to be in good condition so let's reinsert and check clearance/freedom of movement. Any... -

I did not notice there was any movement of the spool when I started. I was unclear which way it came so I initially tapped on it lightly from both sides, Seems like I would have noticed movement. How much is the travel? -

I am fuzzy on the hydraulic flow and what valve does what. If there is pressure to the lift cover and we move the control lever, the control valve directs oil into the lift cylinder and the lift raises? Since this does not happen even with no implement attached, seems like either we are failing... -

I was driving out the valve and bushing together, hard to say -

Does the check valve have any bearing on our situation(Assembly 20 above) -

I am not recognizing anything as being "broken" that would cause a complete failure of the hydraulics. Do you suggest replacing snap ring and seeing what that does? Anything else we should do while we have everything apart? I understand the safety valve was replaced ~5 yrs ago. -

http://ytforums.ytmag.com/photos/6591_sml.jpg By the way we do have the manual. Valve components above, no obvious wear. I was expecting the o ring to be rubber, we have a split steel compression ring. Is that correct? -

Pin looks O.K. How do you remove unloader valve, which direction? -

We have to the cover off and are ready to remove the unloader valve. I notice the linkage is fairly loose and could be tightened with a castle nut (linkage in photo) , how much play is too much? There is also a pin at about the midpoint of the linkage arm with nothing attached. I don't see... -

Despite a blow out of the cardboard gasket we built 1000 psi pressure so I think we can check off the pump and substitute O rings and move on. We replaced all the O rings beneath the plate for good measure. I looked inside the transmission, we have some water there, but rust on the mating... -

Ran the hose from the pump to the fill port, the oil is a bit milky but no evidence of air bubbles. Flow pulses, I am guessing as each piston is engaged? Installed a 3000 psi gauge in the test port on the lift cover, cranked up, put the draft lever in down position, needle did not move off the...
