Product review (5 stars): Replacement part:
This part is better designed than the original factory installed part re: installation and removal. The body of the blower fan on our dryer separated from the attachment nut which is made entirely of composite material.  The replacement part has a metal nut on the end of the attachment nut which makes it stronger and easier to tighten and loosen. Also, the fan body where the nut merges with it appears to be more heavy duty than the factory part.  I had to break the composite attachment nut on the factory part  into pieces in order to remove it from the threaded shaft it screws onto.
