How to check splitter pressure?

I just ordered a new cylinder rod for my splitter. Unfortunately it comes at a considerable cost. I want to make sure the new one doesn't get bent like the old one. Is there a way to check the valve to be sure the pressure limit is working?

Or you can buy just the gauge from northern tool and make your own fittings to match your splitter.

To check pressure install a tee with gauge in the line from the pump and control valve. Adjust relief pressure with the screw under the cap on the side of the valve inlet port.
Usually the rod gets bent due to a mechanical problem.The beam on a splitter almost always flex to some extent. In the pic of your splitter the front of the cylinder is clamped tight to the beam but the rear of the cylinder appears to be sliding away from the beam.

I will be adjusting the cylinder mounting, once I get the new rod installed. Everything will be square and parrellel.
This was a rental splitter. It was bent when I bought it.

Expect to do this also. Thanks

Winner!
