Pressure gauge for FEL.

[retiredmgn]

So I have my gauge. I head to the service advisor at the dealer asking where I should put it.
"Can you show me the correct place to tee it into a line. Guy didn't have a clue but he was trying.
He said these things come in all assembled. We just bolt them on to the tractors. After some online searching and a trip out to the showroom he said his best guess was to tee the gauge into the silver fitting to the right of my joystick. The other lines are to the loader and return to reservoir.
How do I go about testing this hypothesis out. I don't want to unscrew it and have an eye blasted out.
I'm assuming, being open center, all pressure is off if the tractor is not running. I'm thinking back when I had a young guy helping replacing the sills on the barn. A 20 ton jack wasn't going up so he decided to remove the little black plug at the base thinking the jack was just out of oil. Nope. Big mistake. That thing doused him head to toe with hydraulic oil. Wasn't hurt, just had to buy him a new set of clothes.
So can I just crack that line and see if it is the major conduit? I would think, with the engine running and someone pulling slightly on the joystick and me just cracking the nut a might I would get a good idea if that was the main pressure line from the pump.
Problem is when you try to track these lines they disappear into heavy duty castings and with out a lot of dissasembly I'm never going to be sure for what I'm messing with

I don't know enough to answer all your questions, but if you turn the tractor off, lower the loader, and then move the loader valve lever to all positions several times, you should at least not get sprayed with fluid.

If it is an open center valve, I don't think you will ever get a good measurement on any place unless you (for example) connect to a line for a given cylinder and then extend that cylinder until it is deadheaded and then continue to hold the valve while you read the gauge.

I may not understand, and if not, no need to explain...you are the one trying to make progress, not me. I'm just trying to help you make progress.

Just tee the 3000 psi liquid filled gage into the P or IN port of the loader valve.

Then, anything you do using hyd will show up on the gage as the pressure required to accomplish the task at hand.

Engine running and with all valves in neutral, there should be no or very little pressure.

You can use it to check relief pressure and set correctly, and trouble shoot the hyd system.

Look on your loader valve and see if one of the ports has a P or IN stamped by it.

Yeah, thanks for your comments EE. They are so noted. I'm no stranger to heading off into the unknown with nothing more than a hope and a bucket-full-of-promises. I'll get it in the end. Always do.
