BH92 bucket won't open

[BigOgre]

Just as the title says. It won't uncurl, open, dump whatever you choose to call it. The lever moves to curl but will after a bit of fiddling with the lever it will open slowly. The lever doesn't hardly move when you push to the right. Any thoughts?

Update:
I finally got to look at it the other day. It definitely isn't any part of the linkage. I compared one side to the other and that part of the valve just doesn't push down as far. Everything is tight and the handles both have the same amount of slop (very small) in all directions.

Sounds like you need to look closely at the linkage for the operation to see if the spool valve is actually getting moved.

It isn't moving much. I don't have a lot of experience with hydraulics but understand the basics I guess. Can the spool valve be taken apart? I watched the video of the guy adding a thumb and know they are stacked.

It isn't the valve. It is the external linkage for the lever.

Look at all these connections:

I will look again tonight. Getting frustrated to have it and not be able to use it

Thanks for the diagram. I will look tonight

ditto...

Remove the access cover and while moving the right control stick, look for loose bolts/slop in the Heim joint connections. Pretty common.

Don't be afraid to use BLUE locktite on the bolts

I'm not so sure about that unless something is tweaked. I looked again last night and it wasn't moving like it should until I got a little hateful with it.

Did it move and fix your issue?

Well, it moved. It isn't as fast as it was. That was just in my barn, not actually using it.
