8N pump pressure test.

Anyone have any tips on making an adapter to hook a
pressure gage ( 1/4 npt) to the pump outlet port
which is 1/2-20 ?

heap & dirty involves brazing the NPT nipple to a drilled bolt, but there are commercial fittings, too.

Unless you enjoy working for a lot less than minimum wage buy one - they are cheap ($4.00 for the elbow fitting and $1.00 for the cap if you want to leave it on the tractor full time.) The gauge, hose, and box will cost you a little extra ;-)

I can't understand why anybody would want to check the hydraulic pressure on anything. Simple fact it if it won't lift what it should it has low pressure. What you should be doing is figureing out why??????????

I worked on Helicopters for 40 years. The large ones I worked on had two separate hydraulic systems that each had a pressure gauge. If a line blew the last thing you needed to tell you that you had lost pressure was the gauge! If just gave the pilots something to look from time to time!
 
I actually put one on the supply side of my hydraulic valve. Not for troubleshooting but really to see how much pressure my 65 year old vickers pump puts out.

Sorry but a gauge is a great tool for doing that exact thing - isolating and identifying the cause of lost pressure in a hydraulic system. It is the hydraulic system analog to using a voltmeter or ammeter to trouble shoot an electrical circuit,

The issue with pressure tests on an N-series is the internal plumbing is such that you can't effectively isolate and test the individual components. But even so Ford put the test port in and gave you the specifications for a reason. If you can verify that you don't have a leak a pressure test will confirm that the pump is or is not up to snuff. Maybe it is a little worn and making 1200 PSI instead of 1600 PSI. Or you could just guess ....
