Well I H did not BUILD there own , it was Farmed out to OTC and yes the flow rate that he has will work . I am sure the one he has is far better then mine as his will do more PM and probably higher pressures . Now like i said i am not sure what pressure relief your suppose to have as i never looked today to say for sure . but someplace around or above 2150 to 2450 and free flow should be 13 GPM and a decent pump will do 10 to 12 GMP at just before relief . If your pump start falling like a rock as soon as you start to load it at Operating temp and that is between 165-190 the pump has done gone to lunch .

I think I read someplace on the 1086 the relief valve is 2250psi. He stopped by after work today and his gauge goes to 3000psi but he needed a couple more adapters to get it to the right size. I sent a hose-end home with him and the plan is tomorrow to come back by with gauge attached to the hydraulic hose end. We will insert it into a remote outlet and open the flow lever and then hit the remote lever. But looking at your description, I wonder if I would be better served if I attached it someplace else so that I can read pressure as it is trying to lift the load.?. If I attach just straight to gauge it is just going to go straight to the highest pressure it can attain or until relief valve kicks out right? Nothing will happen in this configuration until I hit the lever. Is the pressure supposed to be virtually constant to some degree when hydraulics are in use regardless of the weight or load or does the pressure increase along with the weight of the load. The flowmeter I am guessing will need to have one end of it running back into the reservoir, or do I actually put it inline with the hydraulic cylinder hose?

I realize he may already know these answers but I like educating myself and value advice from those such as you all here. Plus I love troubleshooting a problem. I learned a long time ago that wisdom can either be acquired from a lot of trial and error on your own or from listening to the words of those who have had their own "wisdom acquisition" moments. I am not too proud to opt for the latter whenever I can. When it's over I've learned either way.

You know, I thought about that last night. Certainly wouldn't hurt. I also wondered since I found sort of a cruddy look on that screen and given that the tractor didn't get a whole lot of use last year I wonder if that same "crudiness" could have created issues inside with those flow valves in the MCV that make them not move as well. Especially if those springs were already getting weak from age. It was just a thought and I realize that may be reaching a bit too.

The MCV has NOTHING TO DO with the rear hyd. NONE

Ahhh, thanks for correcting me. It's possible that I used the wrong term or maybe I missed something in the diagram or (more likely) was just a wrong assumption. The valves that I were thinking of were the ones here, but if these are not involved with the remote circuit then I guess they couldn't be a possibility. If image doesn't come through just let me know and I'll try to supply it another way.

Maybe this is the diagram I should have been referring to for controlling flow to remotes??? Hopefully this afternoon's pressure and flow test provide a clearer picture.

Ok, got his gauge tonight and plugged into both remotes. Revved up to 1900 RPM and only got 1000psi at max. On the remote that is used more often I noticed when I shut tractor down its pressure backed down about 350 psi right off then slowly crept down to 500psi.

Does that shed any more light? I mean I am pretty sure that couldn't be right if relief pressure is 2300 to 2500 psi right?

Ok, checked pressure. Could only get 1000psi @ 1900rpm on both remotes.

Pressure checked in both remotes. Both got a 1000psi @ 1900rpm. The one that's used more often leaked down to 500psi after I shut the tractor off.

Tractor Vet,

He couldn't get the flowmeter so since I only have the reading from pressure gauge (1,000psi max) is that enough info to warrant any sort decision or not really? As I understand it the pump is "flow" and the springs/valve/regulator/etc more directly affects pressure due to providing resistance on the circuit. I do realize that is the most simplistic description of hydraulics and by no means addresses all of the concepts of a circuit like that.
