Thanks Dan

The simple answer is yes. How heavy is the disc? Connect a pressure gauge to the test port and see if you are getting 1500 PSI. If you are the disc is simply too heavy for the 3pt. If the pressure is less than 1500 PSI you have insufficient pressure - possibly caused by a weak pump and/or a leaking relief valve.

The safety and releif are two separate valves on the NAA and later system.

TOH...the disc is a little beefy but, my 2N lifts it OK. I will install the new valve and test the pressure, hopefully that will do it. Thanks for the help. Dan

Quoting Removed, click Modern View to see

If your 2N lifts the same disc you have a pressure problem - hopefully the relief valve fixes it.
