Easy to install: Please wear work gloves during installation, simply remove the housing, remove the old blower wheel and install the new wheel. Note that the hole in the center of the impeller needs to be inserted and tightened with a screwdriver, and its size can become suitable. (The missing half piece in the center is to make it easier to tighten the screwdriver.) If you don't know how to install it, just search for 14721091 blower wheel installation on YouTube.
