Only two lines from the valve assy that's mounted on the pump go to the loader part. I presume that's supply and return to and from the loader spools

Ok, well that adds a symptom to the equation and maybe leads towards concerns of the pump itself? I'll post the results of the pressure test. Thanks again for all the insight.

ill have to rely on someone else's expertise here. No it won't raise and curl at the same time. Tractor is new to me, I didn't think that was a symptom I thought it was normal. Should this tractor be capable of doing both?

I have closed the selector valve and turned the loader hydraulics off completely. If it made a difference, it's barely noticeable. If i understand the plumbing part you described correctly, that eliminates the lines being plumbed incorrectly? I probably won't get a chance to get a Guage...

thats a great point. it didnt work when i got the tractor and i have not removed the loader from the tractor or verified the piping is in the correct location. i do wonder if the loader spools would work correctly if that they were backwards? then again, with the loader, if i try to dump the...

ok, that makes sense. so..the next steps... i will chech the feed pressure supplied by the pump and see what the pump is producing. i will also check that the relief valve for the pump is not tripped for no reason, and let you all know what i find.

thanks for the link!

i only have the parts manual from kubota's site. thanks Dan, yes that is exactly the valve. i will do a pressure test there as soon as i can. am i mistaken that the pressure relief in this valve would also provide pressure relieve for the loader functions and power steering?

that helps a lot! sorry, not being hard headed or not listening here just trying to wrap my head around how the system works. maybe my wording came across wrong. i guess my google skills arent that great either, as i cant seem to locate any WSM for this? do you have a link? i did find some for...

yes i have. the linkage under the cap is all in tact as well. the valve seems to work correctly. if i get the arms up, and drop the lever half way down, the arms drop about half way and hold. it will hold weight at the desired height was well. it just wont lift it back up. the circled port in...

i have already pulled the cap and disassembled/cleaned that valve. everything seems in tact, but i guess that doesnt necessarily mean its good.

yes, i know better...one of those stupid things you do in the back forty out of desperation. i can get my hands of hyd. test gauges. anyone know what the capped pressure should feeding the 3PH valve?

if there were an issue with the valve in the cap wouldn't the 3PH drift under a load? it will hold weight for much longer than i would ever expect it to...

i dont have the serial number handy, but the cap is this one

yes it appears it's only there on PS models. i removed it and tried to take the divider out of the equation, ended up losing all hydraulics and PS, but i did not cap the PS circuit as well, maybe that would identify something. the part that keeps hanging me up is, the 3PH will HOLD weight...so...
