## Discrepancy

(CAN) DURING A ROUTINE INSPECTION, IT WAS NOTICED THAT THE HYDRAULIC PULLEY BEARING HAD A CONSIDERABLE AMOUNT OF PLAY.  THE PULLEY ASSY WAS DISASSEMBLED AND UPON FURTHER INVESTIGATION, IT WAS DISCOVERED THAT THE BEARING HAD WORN A VERY DEEP STEP INTO THE PULLEY SHAFT.  BOTH CIR CLIPS WERE STILL INSTALLED PROPERLY AND THE BELT TENSION WAS CORRECT.
