Innards

The pre-analytics' centrifuge decided to give up the ghost today.
The feeder arm that pushes the sample racks that go along the feeder tray decided not to work...so naturally I had to take bits apart to try and figure out what was going on...or rather what was not going on.

I looks to me like the arm (in the centre) has come off is runner and when it has reached the end this has crashed into the sensor that should be located on the green board. That sensor* was found, along with the screws in the picture, on that ledge beneath the belt.

Makes sense to me...
