Product review (4 stars): Smaller than original one.
It is true that the part numbers match, etc. It will also go onto the motor shaft (with appropriate effort). But - the new part is not the same dimensions as the original. It is smaller. Original was 3.7" - new: 3.4" diameter. So it will work, but the efficiency of the fan will be decreased on two counts: the fan itself will move less air and the fan to shroud increased gap will allow air to move from the high pressure area back  to the inlet. I wonder if this was a move to reduce material and lower manufacture costs. I'll use it, but not happy with the part.
