Looks like a 5:1 versaplanetary stage. What motor was driving it, where was this stage in the transmission, and what did the mechanism look like?

It was a 2-stage VP driven by a CIM (pre-CIM Converter). This then drove the sprocket in the middle of the picture through a chain reduction which then rotated the whole arm. We had many failures during the season with this gearbox, and in this case the output stage failed.
