Re: Mori-Seiki MV-Jr ( Charge Tank Bleeding )
Thank You for your response, make the tool change automatic ( M06 ) or manual?

Re: Mori-Seiki MV-Jr ( Charge Tank Bleeding )
Memory is coming back on this. I think there may be a small static holding air pressure on the system at all times. If you fill the system there at the fill point on the cylinder pictured, you might be able to simply open all the bleed valves with just the air pressure turned on. You'll still need to run the tool change plunger with M6 to drive the air out of the plunger cylinder etc.
Hope your machine is at least a little like this.

Re: Mori-Seiki MV-Jr ( Charge Tank Bleeding )
Really appreciate your help, Thank You. Went thru the steps you mentioned and I am still not getting any hydraulic fluid to the top of the system, no pressure at all on the gage the the carousel side and I also mounted a gage on the Charge tank valve to monitor air pressure coming in. I must be missing a step. There is something blocking the fluid from going to the upper section of the system.

You'll have to open the water handle looking valve to show pressure on the gauge. You might also have to activate that tan solenoid you see in your picture. It's also tan in the picture I supplied.
Your bleed valves look the same as mine. Put a little clear tube on the nipple sticking out and feed it into a jar to save from making a big mess.
There should be oil visible in that clear tube left of the silver cylinder. Sort of looks like there is.

Valve is open all the way and the solenoid it activates by switching from auto mode to Manuel. Still no oil pressure to the top. The picture thats shows the charge tank it has a large steel tube on tank next to charge tank, that tube is what feeds the oil to the top of the system and nothing is getting thru that tube, thats why when I open the bleeder valves I dont get air or oil out of it. Driving me nuts, I know I am missing something in the bleeding process.

Maybe that solenoid valve isn't opening. What happens with the bleeders open and you do a M6 tool change or a manual tool release? Get any oil or air out of anything? Remember do not have tools in spindle or active while figuring this out. You don't want one trapped in the spindle or tweaking your swingarm because the spindle won't let go.

Re: Mori-Seiki MV-Jr ( Charge Tank Bleeding )
When I do an M06 or manual tool change with bleeders open, nothing comes out of the tube. Air or Oil, like I mentioned on previous post the upper section of system from where that large tube is coming out of the second cylinder is completely dry. I have checked if solenoid is working by cracking open the tube above solenoid and bunch of oil comes out. Switching between manual mode and auto mode like in MDI switches that particular solenoid off and on.

Without being there I'm sort of at a loss as to how to offer more help. How about filling every tube, including the dry one with hydraulic oil? Mayne why you're not getting anything is the system is lacking too much oil. The trick in any hydraulic system is to have zero air. Do everything you can to get as close to that idea before even beginning to bleed or activate the system.

Did you get your machine fixed yet? Figured it out? If so what did it turn out to be? Very curious.
