ON FLIGHT THE CREW REPORTED AN ELECTRICAL BURNING ODOR IN FLIGHT AND NOTICED THE NR 1 ENGINE SMOKING AFTER SHUTDOWN.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  REMOVED AND REPLACED THE NR 1 ENGINE IAW WC 71-000-00.  THE OPERATIONAL CHECK WAS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.   THE CAUSE OF THE SMOKE WAS DETERMINED TO BE MADE BY THE NR 7 CARBON SEAL.
