Product review (3 stars): non threading bearing holes??
The screws supplied will not easily go in to the bearing.  After trying for 10 frustrating minutes, I finally had the sense to remove from the back of the drum and try to place into the bearing directly.  Still NO GO.  What I had to do was use the supplied screws with a pair of pliers to essentially force in the screw and re thread the holes, then because I trashed the supplied screws doing this, use the old bearings' screws to secure to the drum.  Thankfully that worked but man that was frustrating.  And yes, I did confirm both old and new screws went in to the exiting bearings holes without issue.  Thankfully all back together and working great.
