The Goodman B1368016S Blower Wheel is the genuine OEM 10 x 8 inch squirrel-cage wheel for WGGE4330A045MAB gas package units. The blower wheel is what actually moves conditioned air through your ductwork; a cracked hub, bent blades, or a wheel packed with dirt kills airflow, overheats the heat exchanger, and can throw the motor out of balance. This factory-balanced wheel restores rated CFM and quiet operation.
OEM wheels are balanced and dimensioned to the WGGE4330 blower housing, so they seat true on the motor shaft and won't vibrate or scrape the scroll. Generic 10x8 wheels vary in bore size, hub depth, and blade pitch, which can change CFM and introduce noise. For smooth, on-spec airflow, use the OEM wheel.
Moderate — around 45–60 minutes. You'll remove the blower assembly, loosen the hub set screw, slide the old wheel off the shaft, and set the new wheel to the same position and flush depth. Mark shaft depth before you start. Doable for a mechanically inclined DIYer with a set-screw wrench; if the wheel is seized to the shaft, a technician's puller helps.
