Hydraulic Pressure Gauge and Pressure Reading Test

[Beltzington]

I had same thought at first, looking at pic a little closer it "looks" like the gauge is screwed into top of the hose fitting of hose coming from pump to the valve. If so that should give him working system pressure.

Best I can tell it taps directly into the pressure side via the 90-degree fitting from the smaller hose coming directly from the pump to the valve, the other hose coming off the pump is larger and connects directly to the tank. I have a picture showing this but uploading attachments has been very sketchy lately. No idea why it is taking so long to upload a 80K jpeg, sometimes they load, mostly not.

If the gage is in the series pressure line, it will show pressure of downstream valves.

It should be in a tee in the IN port of the FEL valve. Then it will read any pressure develop in the hyd system.

You have the gauge installed correctly then. If the hose goes directly from the pump to the valve then there is a relief valve in the pump or the directional valve. Most common place for the relief is the directional valve. From what you stated in an earlier post oil pored out when you removed the cap that we thought was the relief valve, did you did not see any spring or ball when you removed the cap? If not I would be surprised that you would have enough pressure to even turn the feed rollers when empty.

Did you drill and tap the hole where the gauge is in the 90-degree hose fitting?

The hose doesn't show in the picture of the gauge.

From the paint on the fitting the gauge is in, it looks like the same 90-degree hose fitting.

The hose doesn't show in that picture.

My thoughts also, it looks like he removed the "in" hose on top, and installed his gauge there but did not
re-install the feed line. He''ll never have any pressure, if thats the case.

That looks like an optional IN port, and therefore should work.

The gage has been there for a while, so it is there for a purpose.

Would you leave a gage in a hole that did not provide pressure?

 

[skyhook]

Your probably right JJ, but in the first picture, there was a hose there and no gauge

 

[J_J]

Question is, do you have pressure on the gage when you use the valve?

 

[skyhook]

I don't know, but in that second picture with the gauge attached, it sure looks like there's only 3 hoses going to the valve to me, bottom return and two working lines.
I may be getting old and blind, lol , but I really can't see a supply line from the pump going in.
I can see the bottom return line "behind" the gauge and to the bottom but no "in".
Can someone or the OP tell me where the feed line is, in that second picture.

There are 4 hoses. bottom of valve ,top of valve, and two work hoses.

I believe your relief valve is the hex cap to the left side first picture.

If the bottom hose is the IN port, then that would be logical as the relief valve is normally close by the IN port on most valves.
