I recently converted my manual steering 1020 to power steering from burnt up tractor. I installed the power steering tower and hooked up the hydraulic lines, but when I drove the tractor I’d have excellent power steering but my three-point hitch would not work unless the steering was at full lock. So I have purchased a priority valve that goes under the right hand step. When I went to install the valve I noticed one of the smaller ports was blocked off on the case with what seems to be a ball bearing. Anyone who has done this conversion can give me any tips on how to remove the ball bearing or does it not need to be removed. Thank you
