I am installing a high pressure gauge on each pump to adjust them... just curious if anyone has left them on permanently ? I cant see what this would hurt as long as there not leaking. The machine is a hitachi ex 300.
they make "gage cocks" just shutoff valves for the gauge so it doesn't keep pressure on it all time & makes it easier to change the gauge when it becomes necessary
It wouldn't hurt, although you would likely want liquid filled to handle the vibrations better.
Alright ..thanks guys. Found some on Grainger for 42.00ea. liquid filled. 0 - 5000 psi should cover me on pressure right ?
not with spikes I've had 10,000psi filter housings crack on the pressure side of the pump if you leave the gauges on they probley won't be accurate after a couple of hrs with all the vibrations and pressure spikes
Take them off. They won't last very long with all the heat/vibration. There is no real benefit. If you want, just put quick coupler nipples on the pumps so you can easily connect/disconnect gauges if needed.
Yep, get some of the test port nipples with the screw on metal protective caps, only way to go.
Sounds like i better leave them off. Ill probably just pull a vacuum on the tank and take them off and install the plugs. By the way do I need to re prime the pumps if I pull a vacuum to put the plugs back in ? I appreciate the help fella's !
I've never bothered to pull a vacuum on a hyd tank when opening those small ports, should only lose a small amount of oil as long as you relieve the tank pressure.
Got it ...Thanks Deeretracks
