## Discrepancy

(CAN) PITCH LINKS WERE FOUND TO BE CONTACTING THEIR SPACERS, CAUSING THEM TO WEAR INTO THE STAKING AROUND THE BEARING ON THE PITCH LINKS.  TAFT 161.6 HOURS.  ALL HARDWARE WAS PROPERLY INSTALLED.  THIS WAS THE SECOND OCCURENCE OF THIS ON OUR FLEET IN 2 DAYS.  THE MFG HAS RECENTLY CHANGED THE PART FROM B345-2 TO B345-4.  THE INSTALLATION IS THE SAME.  THIS WAS NEVER A PROBLEM WITH THE -2 PART.
