## Discrepancy

(CAN) UPON ATTEMPTING TO INSTALL TWO BUSHINGS ON THE TORSION SHAFT FOR THE ENGINE IT WAS NOTICED THAT THE TWO BUSHINGS HAVING THE SAME PART NUMBER HAD A DIFFERENT WALL THICKNESS AND INSIDE DIAMETER. THE SAME PART NUMBER WAS STAMPED ON EACH BUSHING. THE REMAINDER OF THE BUSHINGS WERE CHECKED AND A TOTAL OFTHREE BUSHINGS WERE FOUND WITH THE SAME PROBLEM (TOO THIN OF A WALL). BUSHINGS WERE REMOVED FROM STOCK AND PLACED IN QUARENTINE.
