Yesterday I was moving some stuff in the cab of the 1070 as I am waiting for O Rings for the Control Valve. As I looked at the floor I noticed what looked like a check ball. Having cleaned the floor entirely before I started I knew it was not there before and had this sickening feeling that it came from the control valve. This morning I was looking at a picture I posted on here and now I am sure I know where it came from. I think it cam out of the hole I circled on the included picture. The sickening thing is now that I am reasonably sure where it came from I need to find the spring and retained. Any thoughts on this wonderful developement?
