Many thanks for the detailed step by step video on installing this part. I never would have guess that most of the dryer needs to be taken apart to get the old fan off. In my case, I also had to remove the motor and chisel some of the plastic off the old fan before I could put it in a vice and finally get the old part completely off the motor. Good news...putting it back together went very smoothly, and my dryer is working once again. So nice to not have to replace the dryer or overpay someone to do this job for me!
Note that this was my first time repairing a dryer by myself, thus it was a bit of a challenge. If I were to repeat the same process, it would go much quicker on the second try.
