Bob-
After reading your reply regarding the F-10 loader plumbing, I took a closer look, and sure enough, there is only one line that feeds pressure oil to the valves (I thought there were two, but the other one is the pressure/return for the big one-way lift cylinders). So I may have misled you somewhat, but the pressure line does go in the rear of the grapple/push-off valve, and that must feed the main control valve as well (recall I mentioned the line coming out of the front of the grapple/push-off goes in the front of the main valve). So the line having the Y-shaped relief valve feeds the grapple valve first and then the main gets its oil from the grapple valve. Probably clear as mud, but I wanted to attempt a correction message to redeem myself a little. Hope this hasn't ruined anything for you.
Regards,
Lon M
