I just installed the Sears Washer after ordering the same slideout tray from the factory..
To remove washer from the slideout tray:
The casters were removed from washer and replaced with bolts.
These four bolts went up thru the slideout tray into the caster holes..
Once you slide out the washer all the way, you should be able to get
a wrench (about 9/16") on the back two bolts.. Really tight area, but can do..
The front two bolts come out the same way, only a little easier to get a wrench on..
You should now be able to lift the washer out..
Hope this helps!
