you and the drain pump port is at the right side to install
correctly.) Now place service tool over top of motor shaft
and slide service tool down into pump housing to center
motor shaft to pump housing. Install mounting screws
for motor to pump housing. Remove service tool and
then complete rest of installation of other parts to
assemble motor.
