BTW, the tool arm also stopped working. I thought the 4-way valve here was the problem: http://www.wallacecompany.com/machine_shop/Shizuoka/shizuoka_arm_valve-1a.png Looks just like: http://www.ebay.com/itm/like/151454741685 But it turns out the cylinder seals were so bad that it could not hold enough pressure to move. The valve is where the cylinder normally vents, so I thought the valve was the problem. http://www.wallacecompany.com/machine_shop/Shizuoka/shizuoka_arm_cylinder-1a.jpg Allenair still provides cylinder kits, so I have one on order. The valve o-rings are generic, so I replaced those, but the u-rings are special and I haven't find any. The x-ring is generic, but I didn't want to order a set of 100. The x and u-rings seemed in decent shape, so I put them back in. -- 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
