That's what I'll do I can always change it after the fact I guess if I don't like it.

Yes there are several places close by that can make up I do all the causes and should have all the fittings. I think I'm going to hook it up the way it is with the gauge on the side option number two.

Ya that's the back I'm going to try it with the gauge on the side if I don't like that I can always switch it up.

That's a good point nothing was said about bleeding. Now I know the ram is full of oil already I was planning on bleeding the hose on the pump before connecting to the dab press. but I think maybe I will send them an email and see what they say just for the hell of it.

What you DONT want is air in the ram.

With air over hydraulic air and oil won't mix, at all. Separate circuits. It's been 35 years since hydraulic classes. But I'm pretty sure

Your right. The air pushes a piston, the piston pushes the oil, its just an assist. And your right the pump will have a sealing fitting as will the ram if its like porta power, but the fittings in between, the fittings we are looking at now, are all full of air that will need to be bled. It shouldn't be too hard to do, but I wouldn't do it in the kitchen.

I think I would put it all together, have the ram free so I could put a clamp on it to keep it from moving... this will keep the air out. Then loosen the fitting closest to the ram and slightly pressurize the line. Bubbles and hydraulic fluid will come out of the slightly loosened fitting. When the bubbling stops it should be good. Its also quite possible im missing something and talking out my ass

I use porta power Jack's like that one occasionally at work. Haven't had to bleed. I'd assembly it, pump it up, then release pressure. As fluid goes back to tank air will follow. Might have to do it couple times. I could be wrong.

But never crack it under a heavy amount of pressure. Or you'll need more oil. Lol

If the assembly with the gauge has hydraulic fluid in it than your right. I thought he had taken it apart. If he assembled those fittings and theres air in it and its between the pump and the ram which is what im yammering about... I think
 
Air should return to tank. Tank has a vent or breather. Air over hydraulic systems are really cool. I haven't worked on many. But I have a table lift in my garage that's air or foot pump. I always pump because it only takes few pumps and it's up.

Hopefully I don't sound like a jackass. But I'm a service tech for a large company. I work on different equipment all the time. For better part of 30 years

Your pump has it's own oil res and a built in separate circuit for air to push the fluid circuit. Does it have a schematic with it

Pump has not arrived yet supposed to be here today.

The assembly in the pictures is just loosely put together for demonstration purposes I have put it together permanently now as shown in option two. The fittings with the gauge has quick disconnects on both ends for the RAM and for the hose. So my plan is to hook up the hose end and bleed the air out by running the pump with the other quick disconnect fitting depressed so the air will come out when I see oil I'm done let go of the pump let go of the quick disconnect everything should be bled. And I will just hook up the last quick disconnect to the ram and should be good. What do you think?

If you had a leaky valve in the middle of a hydraulic line that went from a pump to a ram, and you replaced the valve would you bleed it?

No probably not. I think the air would return to the tank and self bleed through the vent. If it was meant to be bled, it would have a bleeder screw.

I think cycling it manually back and forth few times will do the trick. Try it first, it will not hurt anything. I'm guessing dab press will tell you not to bleed it. Hyd fluid can be dangerous if it is injected into the flesh. I saw a video when I was in college that showed the aftermath of a dude that tried to fix a leaky fitting under pressure. When he put a wrench on the fitting and attempted to tighten it, it cracked and under high pressure it injected into the flesh. He lost his hand

Good point i might wait for a reply from dabpress.
