Compactor would not return to parked position

The big problem was how to get to the drive since the ram was down in the compression stage. I was able to remove the two door hinge pins and with a bit of prying and movement was able to disengage the door lock and totally remove the door. That removal disclosed the broken nylon trunion nut. After digging out all of the compressed trash, I used a small car jack to raise the ram slightly and remove the nut holder and broken nut. In replacing the nut, I had to decide at what point in the ram travel to install the new nut. Realizing that at full compression the nut would be fully taken up on the screw, I raised the ram perhaps 1/4 to 1/2 inch to allow for play, and after greasing the screw well, tightened the nut all the way against the nut mount, and replaced the nut holder. After several test runs, I replaced the door. It works now. Note- the original nut was nylon which stripped and split. The replacment was metal, which should be better.
