## Discrepancy

(CAN) DURING CRUISE AT 13,000 FEET, THE CREW NOTICED A REDUCTION IN MANIFOLD PRESSURE ON NR 2 ENGINE THAT COULD NOT BE REGAINED WITH THE THROTTLE.  THE AIRCRAFT DIVERTED AND LANDED WITHOUT INCIDENT.  POST-FLIGHT INSPECTION FOUND THE TURBOCHARGER ROTATING GROUP WAS DRAGGING AND PREVENTING PROPER TURBO OPERATION.  THE TURBOCHARGER WAS REPLACED.  THE ENGINE GROUND RUN SERVICEABLE AND THE AIRCRAFT RETURNED TO SERVICE.
