Apparently the servo bores are not that precisely machined and a tight one is not uncommon. He was not surprised to hear of my type of difficulty and explained how in his shop occassionally they encounter the same thing. Gave me a call on his cell phone to see if he could help resolve the problem I was having. He had just had a long delayed flight back home from his vacation spot. I was cleaning up when Greg Ducato called. The rest is history, snap ring went in easy. "POW", the cover popped down into the bore, down past the snap ring groove. When I say hard, I mean with both hands just as forcefull as I could. I positioned the leverage bar over the cover and pushed down hard. I said to myself well, I'm ether going to "make it or break it". Same deal, the cover would just not go down into the bore far enough to allow the snap ring groove to be exposed. Positioned the leverage bar over the top of the cover and pushed down firmly. Pushed the servo cover down into the bore and thought, here goes another o-ring seal. I went out in the garage, crawled under the R, carefully lubed everything up, servo bore, all the seals, slipped each piece into the bore carefully making sure the servo was square and rotated easily in the bore. I was waiting for a reply from Greg, to hear from the expert. After I had taken the servo assembly out again and made sure it was put together right, I went over to my GMC dealer and picked up another servo cover o-ring. Yesterday I was sitting around pondering all the suggestions that everybody had posted.
