That is bad news. I would say very bad news. You should be getting just under 9 GPM. The silver lining is you now have a clear problem to focus on. Dan

Now your 3pt is underpowered. Why did you decide to set the loader relief lower than the tractor? Dan

That's the loader "power beyond" hose. If its not fully connected you will get your symptoms. Dan

Personally I never got past that part although I might be kind and call it "aggressive operating techniques." Dan

You can buy a premade hose assembly with straight JIC swivels from Surplus Center for $14 and a 90 degree JIC swivel adapter for $4. Even with expensive shipping its by far the cheapest way to go. Dan...

Sorry gor my lack of clarity. I was not talking about torsion. I was suggesting there adfitional ways to load that shaft. Dan

It may not be that simple. You can do crazy things with backhoe hydraulics. Dan

Sounds to me like you have a problem on the pressure side. What is the "BH bypass hose:? Dan

Your local Fleetpride can do it while you wait but they are pricey. Assuming its a 36" long 3/8*;hose with JIC-08 swivels Discount Hydraulic Hose will make it for $38 End 1: FJX90-06-08 End 2: FJX-06-08 Hose: SAE100 R16-06 x 36" I would make it while you wait for the same price Dan

Does this tractor have a loader on it? Dan

Your goal was to measure flow. Disconnect the hose at the loader vakve - not at the block That way you dont make a big mess. To measure pressure leave hose connected to outlet block and connect the gauge to other end of hose. I would guess the hose has a JIC-08 female swivel end and the gsuge...

Based on that narrative my first guess woild be the power beyond on one of the attachnents is not fully connected. Dan

Any process including pen and paper is subject to human error and the same sort of misanalysis in your example. Modeling with FEA isnt infallible but it lets a designer do a far more comprehensive analysis. In the long run that produces more reliable outcomes FEA is the mathematic process used...
