testing 8N hydraulic pump pressure

[Bill Crowell]

Is there any easy way to connect my hydraulic pressure gauge to the hydraulic test port on my 8N without having to drain all the fluid first and then re-fill after the gauge is connected?
I think if I were to try to connect it without draining the fluid first, it is going to make a big mess.
Just wondered if I am missing something. Thanks a lot.

Just a small mess if you are quick about it. Have the adapter ready to screw in as soon as the plug is out and you will only dump a few ounces.

The test port is a tee into the lift circuit making it impossible to say if low pressure is because of a weak pump , leakage in the lift cylinder, and/or a malfunctioning pressure safety valve. Isolating the pump to test it requires some innovative thinking ad a bit of fabrication.

I'll give that a try then, Hokie. Thank you so much for all the help you have given me. I figure if the pressure measures up to spec, it probably has a bad cam follower pin, but if the pressure is too low then I've got more troubleshooting to do.

Reasonable assumption.
