## Discrepancy

(CAN) ON THE ACFT SHUTDOWN, NOTICED THAT THE MAIN ROTOR WAS SLOWING FASTER THAN USUAL.  THE DRIVE LINE, ROTORS, WERE HARD TO TURN BY HAND.  THE HYDRAULIC PRESSURE WARNING LIGHT NEVER WENT ON.  INVESTIGATION REVEALED THAT THE BELT DRIVEN HYDRAULIC PUMP DRIVE BEARING WAS SEIZED.  THE HYDRAULIC PUMP DRIVE ASSY WAS REPLACED BY A NEW ASSY.
