Product review (1 stars): Ordered 285753 but received 285753A which failed during the second wash load.
I ordered part number 285753 from North America HVAC but recieved the 285753A (the alleged "heavy duty" version).  Do yourself a favor and seek out the all plastic model (285753).  I order 2 (both were the "A" model), installed one only to have it fail during the second load of wash.  The issue with the "A" version is that the metal ring will easily separate from the plastic body given the amount of force needed to spin the tub.  I noticed that while the plastic body does have squared notches cut out for the metal ring the metal rings teeth are rounded on the edges which caused mine to fail due to separation. I'm returning the extra one I bought as I don't want to have to replace this part after every 2 wash loads. I was able to find the all plastic part on the e site by the bay
The second picture shows the all plastic part I purchase from another website.
