1070 case hydraulic valve? (remote valve)

farmerscotty · May 25, 2010

Ok I thought the shop I took my tractor into this winter repaired my hydraulic valve.....well they missed it. one of my remote valves won"t detent......if you use that set for the round baler tailgate.....to get it to open and stay open you have to hold it pulled back otherwise it will let the tailgate down. I got a loader I am putting on this before I start haying....where is the valve and what do I need to do to fix this I figure it is a spring......but I have no clue where it is.....too many irons in the fire......mom is 92 and I am a caretaker.....so I am running my life away.

thanks in advance......appreciate it.

photos woould be great or even step by step..or where I can find step by step instructions.....

In all likelyhood the thermal relief valves in the RH endcap on the Dual Remote valve have failed due to overheating. They are made of a nylon type material and warp and distort. There is a body, a spring guide and an oring involved in the repair. The spring and ball could probably be used over but the cost to replace all would not be that much more. there are two of these in the RH endcap. Make sure it is the RH hoses that are leaking back as viewed from the rear. mEl

so where is this located at?

mEl, don't know if you are able to provide input to your Case engineers or not but nylon or Teflon doesn't have the strength to do this job. A better polymer choice would be a Ryton filled Teflon, Vespel or PEEK. Nylon may not have the compressive or tensile strength to do what they are asking in this case for long term use, I believe. (But it is cheaper than the ones above by a few pennies per part.) Just this oil tool engineer's humble opinion.

J, could be that you are right and I may be wrong on the composition also. They are a blue substance that definately does not do extreme heat well. I just used nylon as a descriptive general term.

The valves are located in the right hand cap that fastens on with 4 -3/8 bolts. the casting that the RH remote hoses and fittings fasten to. be careful as you remove the endcap as there are springs and balls and retainers to contend with. if you are working on grass spread a large tarp so all is accounted for. a service manual would be invaluable to you and I recommend at lease a copy of the appropriate pages from a CASE manual. mEl

back of the tractor, under the fuel tank on top of the differential housing. follow the hoses from the remotes.
