## Discrepancy

UPON THE MID-LIFE REMOVAL OF NR1 ENG FOUND THAT THE WASHER USED AT THE TRUNNION TIE BOLT HAD A O/D THAT WAS TO LARGE FOR THE USE OF TOOL (T900175-1).  THIS TOOL IS USED TO PREVENT THE TRUNNION CANISTER FROM MOVING. IAW CAUTION FOUND IN MM 71-00-00 PG. 405 B. 25. ANY MOVEMENT OF THE TRUNNION CANISTER ASSY DURING REMOVAL OR INSTALLATION WILL REQUIRE THAT IT BE REMOVED AND INSPECTED FOR DAMAGE. THE REPLACEMENT OF THE CANISTER MAY BE NECESSARY IF IT IS DAMAGED. THE CORRECT WASHER, P/N MS20002C14 WILL ALLOW THE USE OF THE REQUIRED TOOL (T900175-1)
NOTE: THIS IS THE FIRST TIME THE ENGINE WAS REMOVED FROM THE ACFT.
