The coupling that keeps shearing
Case sealer, flight-bar drive: motor-to-gearbox jaw coupling · 12 min
The case sealer's flight-bar drive has shredded its third coupling spider. Stores keeps handing out spiders and the operators keep fitting them. The dead element is on the bench, a new one is in your hand, and the line needs the machine back. Fit it and run it, that part is easy. The work order only closes when you name the condition that keeps killing them, because a coupling element that dies this fast is being murdered by something outside it.
