One of the illustrations that I have seen of the D7E shows the front idlers as sprockets that appear to be identical to the drive sprockets in the rear. Why is that? Those front sprockets are not driven are they? I assume that they are acting only as idlers. But what would be the reasoning for using sprockets as idlers?
The only place that I have seen that practice is on those little Chinese dozers that are being imported. With them, I had assumed that they merely decided to save the cost of tooling up for front idlers when they could just use another of the existing sprockets used to drive in the rear. But I can’t see Cat doing it for that reason. Has any other crawler manufacturer ever used a second item of the sprocket for the idler?
