## Discrepancy

INSTALLED NEW SHAFT, PN 0894000-12 ON BOTH MLG AT 3520.9 AND AT 3620.9.  BOTH SHAFTS WERE CRACKED ON RT SIDE.  THE NEW STYLE SHAFTS HAVE A LARGER DIAMETER ROLL PIN AND THIS HOLE IS WHERE THE CRACKS ARE STARTING FROM.  THE NEW STYLE SHAFTS ARE MADE WEAKER BY HAVING A BIGGER HOLE IN THEM.
