Product review (4 stars): Part not identical to the one that I removed
Part received had label on box indicating "LG Electronics 4681EA2001...n" Pump and Motor Assembly.  Purchased Item description indicates 4681EA2001T, and I noticed another item listing in Amazon for a 4681EA2001N.  Both indicate they would work on my WM2501HVA washer but the former item has many reviews and the latter had none.  The part I removed from my machine has the identical appearance to the photo for the item 4681EA2001T, but the part received has a slightly larger dimension for the black rectangular end shown in the left part of the photo, and there is no cutout.  There is a white cover that is over the old motor/pump and can be removed from the old pump to put on the replacement, however, due to the slight dimension issue, it is a poor fit, but can be forced to a point where it will stay on.  The part does mount on the drain assembly and appears to work well, which is the important thing.  The pump may not need the cover, but since it was there, I figure it has some function.
