Product review (5 stars): Perfect fit for Amana Washer
Perfect fit for Amana Washer.  IMPORTANT:  Not shown, but comes with the 3M sealant for the Tub Seal.  Sealant is normally $20 by itself.

Good luck, it took me 3 days to get that hub off -  Had to cut it and use a bearing puller.  Electrolysis had welded the aluminum hub onto the steel transmission shaft!

Also, if you're replacing the main bearing because of noise, be aware the replacements are all China-made now.  Buy a high-quality Japanese 6206Z and pop into the bearing housing.
