3 point / diverter valve/ rear hydrolics porblems

yardtoy1 · Apr 23, 2013

I have a kubota 3010 DT with a (FEL) I added 2 hydrolic lines to the back. I taped into the diverter valve and added two (T)s one line to the out port and one line to the tank port ( I drained the tank to do this ) after my install was completed I added a new filter and filled tank with new fluid. I started the tractor worked the (FEL) slowly to Make sure no air was trapped, all good... 3 point would not work, I did notice the 3 point would work when I curled the bucket. At this point I Disconected the (FEL) turned the screw on the diverter box and the 3 point worked great, Ok. reattached the (FEL) turned the screw on the diverter , started the tractor and 3 point doesn't work unless bucket is cruled. At this point all I've done is added 2 lines to the back of the tractor with quick disconnects. Wondering do I have a stuck valve in the diverter ,I've tried to find a schmatic of the valve but to no avail ,I'm hopping some one else has run across this and figured it out,
thank you all

You can't use tee's. The diverter valve must be plumbed so oil goes through it to get to the 3 pt valve IE it must be in series. When you curled bucket you blocked the path of the oil forcing it to 3pt valve.

Tx Jim is right, all the valves must be in series.

If you want a simple set of QD's to the back, then add a set of hoses and QD's to the diverter valve and when you need the outlets at the back, flip the switch and the back QD are activated. Of course the curl will not work with the fluid diverted.

For outlets at the back, you should obtained a two or three spool valve as your remotes and hooked it up to the PB from the FEL.

That will give you three sets of QD's to the back for whatever, maybe things like T-N-T, log splitter, post hole digger, etc.

you guys are great, now i understand thanx so much
lets say i have the loader in a 1/4 up position and switch the selanoid , will the FEL hold its position ?

one more question, I understand about the contuinous loop but rite now off the 2 T in installed they go no ware? would that interupt the contuinous flow that seem to be interupting the 3 point from going up
