I replaced most of the seals and put a few decent ones back in. 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 [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
