I recently purchased a grey market Kubota that has a "new" Koyker 110 loader on it.
The other day I went to move some dirt from a hillside I've been chipping away at and when I pushed into the pile and went to curl the bucket back it momentarily started to come up and then dropped.
I played around for a minute or two and figured out if I only slightly pushed the lever it would curl fine but if I pushed the lever all the way to the left it acted like the valve opened all the way up back to tank. Curling the bucket down is no problem as is lifting and lowering the main arms.
So now I have to kind of feather the lever in order to get the bucket to curl. Anyone ever experience this type of "failure"? I can tear into it (the valve) but before I do I wanted to check and see if this is a known problem (I couldn't find anything doing a search) or at least get an idea for some of you might think.
I'm pretty handy with industrial hydraulics as i used to work on monster hydraulic presses so I'm okay with working on it. I'm just trying to make sure I'm not overlooking anything obvious.
I've never had one of these types of manual valves apart so I'm not sure what the mechanism inside looks like or how they operate. I also have not seen a schematic of the valve anywhere.
Anyone have any suggestions before I pull this thing apart?
