When I tested the valve, it behaved the same -- leaking a lot of exhaust air and not moving the arm. Further investigation indicated the cylinder seals are leaking badly. http://www.wallacecompany.com/machine_shop/Shizuoka/shizuoka_arm_cylinder-1a.jpg The left half is the air side which pushes or pulls the arm. The right half has hydraulic fluid and a petcock that sets the air push/pull rate and damps motion. Now I'm another week out of commission to order and wait for more seals. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

I'll post pictures and dimensions tomorrow morning. I recall the seal being 1" OD, .75" ID and .103" wide, but I'll make sure before I post the pictures. Instead of shuttle, I think I meant to call it a bobbin which actually may be a hydraulics term. The valve body has a .43" diameter rod which has a short 1" diameter piston screwed to each end. Each piston is driven by a solenoid. I need the two piston seals. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
