IBT (transfer belt) Back-Up Roll Drive Coupling - (BUR Drive Nose)

This little drive coupling piece is found on the BackUp Roll Assembly (BUR Assembly) near the bottom front end of the IBT Belt Module.  It is responsible for driving the fly wheel at the front end of the 2nd BTR Assembly.  It is known to break causing all kinds of friction inside the IBT belt which can wear out the belt and the 2nd BTR Roller where the Backup Roll presses against it.
