Head shaft assembly

The feeder breaker is equipped with a head shaft (Fig. 33) located on the discharge end of the conveyor. The head shaft is driven from the left hand side via a hydraulic motor directly mounted to the head shaft.

IMPORTANT! Weld on split sprockets are available for replacement/emergency rebuilds. See the Cat® parts manual for your machine or contact your Cat® service engineer.
