I am finishing replacing the parts after rebuilding my hydraulics on an 8N. I installed a new cylinder and NAA piston. I also replaced all 4 valve assemblies in the pump. I put the top cover in place and torqued it down. I lifted the pump assembly into place, left the bolts finger tight and slipped in the PTO shaft. (Made sure the tip of the lift control arm was nicely nestled into the hole in the valve rocker lever.) Torqued the PTO shaft, then the pump bolts. Then I wanted to check the movement of the lift control arm to see if it moved the valve right up to, and touching the body of the pump, as indicated in the FO-4 Shop manual page 91, Figure FO136. I was surprised to find that the valve rocker lever contacted the pump housing about half way up on the Touch Control Lever. What could be causing this?
