What was found
DURING THE ANNUAL INSPECTION, IT WAS NOTED THAT THE RT TURBOCHARGER HAD A LOOSE TURBINE HOUSING. THE TURBINE HOUSING EXHIBITED SIGNIFICANT PLAY WHERE IT MEETS THE CENTER BEARING HOUSING. IT APPEARS THAT THIS HAD BEEN GOING ON FOR SOME TIME. THE TURBINE HOUSING IS HELD IN PLACE BY BOLTS THAT PROVIDE PRESSURE TO KEEP HOUSING FROM ROTATING WHEN PROPERLY TORQUED. IT IS VERY IMPORTANT TO CHECK SECURITY OF THE TURBINE AND COMPRESSOR HOUSINGS AT EACH ANNUAL INSPECTION. RECOMMEND AT LEAST A CURSORY CHECK OF THIS COMPONENT DURING OIL CHANGES. REMOVED AND REPLACED RT TURBOCHARGER WITH AN OVERHAULED UNIT.
