I removed the trigger and the plunger came out and then I unscrewed the piece that the plunger rides in and out came the ball and the packing. All told could be a ten minute job. The O ring is a TIGHT fit on the plunger and it took about ten minutes to get it on the first stage and then I broke it trying to get it over the hump and into the seat groove. I had purchased two O rings so I had a second to install. After a good night sleep and much thought I soaked the O ring in boiling water and it went on the first stage ok. I soaked the plunger with the O ring in the first place and then it rolled into the groove pretty easy and the whole thing went back together in a few minutes.
