## Discrepancy

THIS PRESSURIZED MAGNETO WAS REMOVED AND DISASSEMBLED FOR THE 500 HOUR INSPECTION.  ALL THE INTERNAL HARDWARE WAS FOUND RUSTED.  THE DISTRIBUTOR GEAR, DRIVE GEAR AND DISTRIBUTOR BLOCK WAS FOUND COVERED IN A FILM AND NOTICEABLY SOFTER THAN NEW EXAMPLES.  THIS IS A RESULT OF MOISTURE IONIZATION.  RECORDS CONFIRM THAT THE MOISTURE FILTER IN THE PRESSURIZATION LINE HAD BEEN REPLACED REGULARLY AD 88-25-04 ADDRESSES THIS PROBLEM IN EARLIER SERIES MAGNETOS.  SHOULD BE AMENDED TO INCLUDE 6300 SERIES, PRESSURIZED MAGNETOS.
