3PH arms won't raise on KAMA 454

Sound Guy,

He is a good friend and I don't blame him. Because I was in a hurry, I just put the yard box at his house.

Well, Chip quickly sent the replacement PR valve and I installed it while draining and flushing for the 50 hr service. I did not notice anything out of the ordinary. But needless to say no change. Lift arms only work when I bump the FEL controls.

Now that has been eliminated, what could be the next to look at/change?

With the lift box hyd tank empty, could you see how the cams work on the lift valve plunger? did eveything appear to be functioning? This has got be a bit baffled. I sure do hate admitting this on a public forum!

I noticed if my loader is in float and I raise the lift that the loader raises. sounds like the reverse is happening here.

Chip,

I did move the Draft and position lever to see how this works. The plunger goes in/out smooth. Is the plunger a valve of sorts? Could this be the issue? I did take photos but it does not show much.
