Hi Nick My name is***** will try to help. sounds like there might be a problem with some linkage disconnected or there is a failed o ring allowing the pressure to bypass. You will have to remove the housing again to inspect and retrace your steps unfortunately. Let me know
Hi Nick, thanks for the update. I need to opt out for the pressure testing part on this model as i do not have a copy of the service book. there is an expert on here by the name of Kevin who can likely help with this or another expert. i am going to opt out and send a message over to him as well. i do not know his schedule but dont respnd back or the question will get locked back to me.
hey nick my name is ***** ***** you did the load control shaft did you have both draft and lift levers all the way in the down position? it is possable to install the shaft and miss the draft arm below and that will give you that same result. as far as testing the valve... if you have your 2200 psi at the SCV it will be at the rockshaft. test there and let me know. if no pressure its possable that the priority valve has jammed or other issues
any luck here?
welcome nick. what about the load control shaft that you said you changed? when you changed it did you have both levers full forward?
so with your tests you have verified that it is not a pressure issue which is good. are the arms stuck up or down?
NO not the forks on top im talking about the load control shaft that contacts the draft arm at the bottom of the transmission case
it is posable to have the draft sense arm on the wrong side of the load control shaft
if there stuck down i would put $$ on the load control shaft not being installed correctly
then really the only other thing it could be is a busted roll pin on the internal linkage assembly in the rockshaft valve
you have great pressure, the arms are free, you have verified that the linkages are in place correctly and no parts missing
whats left really?
are you online with JD parts? so that you can see the break down?
i would download he tech manual..there about $20 online

go to the hydraulic section for your model and scroll down to "rockshaft control" there it show that roll pin i was talking about
