Wear Of the bushes will lead to a requirement to tension the tracks, on System One chains where the idler runs on the bushes (according to Cat this doesn’t happen as the bushes roll, but it can, again to a minor extent.Out of interest, how does one measure/calculate track wear as a percentage? Is it as simple as comparing to the track depth of a new track? Or is it more complex than that? Same for steel?
