## Discrepancy

VENT BLOWER WHEEL MOUNTING BOSS INSIDE DIAMETER TOO LARGE CAUSING EXCESSIVE PLAY BETWEEN THE ARMATURE & WHEEL.  THE TECHNICIAN NOTED DURING ASSEMBLY OF THE ARMATURE & BLOWER WHEEL, THAT THE WHEEL WOULD WOBBLE AFTER BEING SECURED WITH THE SET SCREW.  THE MATING SURFACE OF THE ARMATURE DID NOT APPEARED TO BE DAMAGED. A SECOND WHEEL WENT ON TO THE ARMATURE SHAFT WITH MINIMAL PLAY, TYPICAL FOR THIS SETUP.  UPON VISUAL INSPECTION TO THE WHEEL IN QUESTION THE MOUNTING BOSS DOES NOT APPEAR TO BE EXCESSIVELY WORN.  REMOVED BLOWER WHEEL FROM SERVICE.
