I was going to post these in the digging over drive motors thread when the subject of chains and pins and bushes came up and never did quiet get around to it. I thought that some of you may have never seen the tracks on a large excavator, they(maybe not all) don't have track chains and grouser plates, just one track segment and two pins. The pics will show better than I can describe. The drive thingamajig is called a tumbler. These photos are of a Hitachi 5500, the pic of the top of the track I had to hold the camera up over my head to get it. :cool2
