Product review (4 stars): Amana/Samsung Idler Pulley
Exact duplicate of the original pulley - The only reason I can't give 5 stars is that the original one melted, and they only make plastic wheel. Not sure what they were thinking, it's a dryer which works on HEAT, but if I get another few years out of the unit that would be fine with me.

Easy install, just have to take the entire dryer apart.
