My 1955 to 35 project. Many of you have given me good advice on this project so I am back again. I had to replace the hydraulic cover because the old one was cracked badly. I am having a problem with the replacement. The position operation rod that actuates the pump valve has a problem that I can't solve. When the position control arm is pushed to the down position the pump controlrod goes goes forward and slips into the detent on the bracket. Is there an adjustment that will prevent that from happening or will enable it to come out of the detent when the position cotrol lever is in the up position.
