Now, tilt the washer fully on its back. Put a few 2x4s down as spacers so it’s not resting on the drum drive. You’ll now have clear access to the drain pump motor mounts from the bottom.

Install the two side (black) rubber mounts and one front (red) rubber mount onto the drain motor (first pic) and then manipulate the drain pump front mount into place starting with the red rubber mount, and then pull the drain pump black rubber mounts into place from underneath (second pic).

Turn the washer back upright, install the flimsy bottom pan, hoses, drain, and run a test load to check for leaks and proper operation. Then install the back panel, and you're finished.
