Hello,
I have a 42' 9n and at first the hydraulic lift wouldn't lift with any implement attached to it. Although, the lift would go up with nothing attached.
I removed the inspection plates, both of them, and no obvious leak was found. Then I checked the 'Spring, Hydraulic lift draft control' and has quite abit of slop when the lift was up. I tried to turn the yoke but as I have read, it's stuck solid to the plunger.
Then something changed, now the lift would not go down. So, I reached through the inspection port and felt for the control valve at the bottom of the forks. After some effort I located the valve or what felt like a 'T' and reattached it to the bottom of the fork. (I'm glad no one was watching as I was hugging the centercase, with one arm in either port) Well, the lift went down and then up and stayed up. Rather than beat my head on the differntial, I figured I would ask for some help.
I did find quite abit of sludge at the bottom, near the pump and the oil is just starting to show signs of water migrating into it.the oil was moving quite well with only alittle bit of rostertailing (abt half inch high) in the pump base, flowing towards the left side port.
I saw a post which suggested using a torch to loosen the yoke, is that the only way?
I don't think that removing the top or bottom plates will help in figuring out what is wrong.
I just not sure where to start.
