Product review (5 stars): works as shown on YouTube
Replaced this pulley assembly in 2-year-old Samsung dryer using YouTube videos as a guidance. It took few trials and errors for the person doing this for the first time in life (me), but by the end of the day the dryer came back to service (and working for 2 months since repair at the moment of review). The part was exactly matching original one, and fit the place perfectly. The belt was replaced just along the way, while now I realize that it was not really necessary.
