Product review (5 stars): Worked with no problems.
No problems, worked perfectly with my ancient Maytag A512 washing machine. To have a chance of getting the large round silver silver nut off (depicted in the parts image) you will need the specialty tool made for the job and a hand held small sledge hammer, in my case I used a masonry hammer which is similar to a small sledge, a regular hammer won't cut it. Note that the part is left hand threaded, turn to the right to loosen.

This was purchased as part of a tub bearing replacement, the bearing and tool were purchased very reasonably at that other place (think Sunny and Cher..I got you Bay)

The only real problems encountered in the whole bearing replacement was a lot of clean up time (it hadn't been apart in 32 years) and I had to address some rust around the hole where the bearing goes through. More clean up and some touch up with of Hammerite paint which is a quick drying rust inhibiting enamel like paint. I happened to have the paint on hand and color didn't matter as the seal covers the surface where the paint went. I did end up having to put on a new drive belt, replacing one that was not too old actually, the extra resistance of the failing tub bearing caused it to wear prematurely.  All in all a very reasonable project to do which consumed most of the day with the clean up and paint but at a pleasant cost compared to replacing a vintage dependable  washer with an expensive less reliable new one (read the reviews on a lot of new washers :\ )
