I was trying to adjust the clutch on my 450ES. I would try to loosen the jam nut and the adjuster would spin with it. So I tried spinning the jam nut out far enough hoping the adjusting bolt would bottom out and the jam nut would spin off the adjusting bolt, but that didn’t happen. I finally got the Jam nut off the adjusting bolt and cleaned it up and rethread it back on. I then when through the adjusting procedure of spinning the adjusting bolt out till I felt resistance and came back ¼ turn and tightened the jam nut. Now I have no transmission at all. It engages but when I rev the engine up there is nothing there. What did I do?
