Dillon Precision Index Sprocket RL550 – 13720

Dillon Precision Index Sprocket RL550 – 13720

The 13720 Index Sprocket is the indexing gear for Dillon RL550 presses. Dillon lists it in the Platform & Components exploded view on page 63 of the RL550 manual, in the group that manages the manual advancement of the shellplate.

On the RL550, the shellplate advancement is controlled by the operator via this wheel: the teeth define the station positions and work with the 13891 detent ball and the corresponding 13997 spring, which hold the platform in position between strokes. Rounded teeth or a worn ball result in misaligned stations.
