Case 1070 remote hydraulics - Single action valves?

I just bought this Case 1070 a few weeks ago and l don't know much about it.

The steering, breaks, and clutch all work well, I does appear to have a rather new hydraulic pump.

I had used the remotes on some single line hydraulic cylinders such as folding a fairly heavy 15 foot brush hog and they worked very well and quick.

So far so good, now here is where I had problems.

Today I tried to open the back gate on a round bailer and it just cracked it open 4 inches and would not go any further. Then I tried to shut the gate and I got no movement at all as if the safety valve was shut but it was open.

I put the wife's pet tractor on the bailer and gate works fine. At this point I am just getting "go to " looks from the wife.

I put the 1070 on the wheel rake (which looked rather ridiculous which is further aggravated because the field is RIGHT by the road). But the wheel rake goes up and down rather nicely.

My wife is really good. She went ahead and raked hay with the 1070 but when I tried to call her she would not answer the phone.

When we got done bailing I begin to experiment with the remotes with the single line cylinder on the rake. The top hoses on both remotes has good pressure and flow.

The bottom hoses on both remotes have no flow at all. But the tractor does pull down a bit as if it is trying to operate the cylinder.

My question is - can these valves be set to single action? and if so how do I set them for double action?

A buddy thought I might have some bad female connectors on both bottom remote lines. I will replace them tomorrow.

I need to get this figured out and fixed before my wife takes her tractor and quits helping me in the hay field.

Thanks in advance for any mechanical advice and social/marital advice will also be gladly accepted.
 
Is your 1070 new enough to have ISO couplers, or has it been converted to Pioneer couplings, or does it still have the old Case couplings. My first thought is that you have a bad coupler that is working like a directional flow check.
I assume that you are using the two top and the two bottom couplings as pairs correct way, not RH anLH, wrong way.
When using single acting cylinder, make up a hose about 18" long with a male coupling on it and plug it into the tractor coupling opposit the one you hooked the cylinder hose in and hook the other end to a return in the tranny. Many people just stick the open end into the fill tube and wad a rag around it.

That's what I was thinking too. They are paired together as a top pair and a bottom pair. Not a left pair and a right pair. I was at a dealer once and they had just sold a used 1070, and the guy was on the phone cussing them out for selling them a tractor with junk hydraulics. I told them to ask how he had them hooked up, and he had both hoses hooked up on one side. He switched it, and apologized when it worked like it should :)
 

Right there may be there error of my ways. I was trying to operate the bailer with both hoses hooked to the left hand pair. :oops:

As for Adirondack case guy's question, this tractor has Pioneer couplings that have a bit of red paint left on them although I couldn't be certain if it was factory paint or spray paint.

I was fixing to go to town to get new female ends but instead I'll do like the guy in mshultz's story and try hocking the bailer up the right way and see what happens.
 
I'd bet she works just fine once hooked up correctly.

That said, I have never heard of venting the other side on a single acting cylinder.


Our girls have had untold 10s of thousand of cycles on SA cylinders with no side effects.
 
Well how about this. Hook the hoses up properly and things work like we expect them to. I think I'll get the wife some snazzy gadget for her tractor and all will be good again!

Thanks guys!
