Place the unit face down. You will see 6 brass Phillips head screws through the plastic housing. You will need to remove 5 of these. The screw on the top left side, one down from the corner, does not need to be removed. Just remove the 5 screws on the corners.
Below the motor, beside the plastic assembly where you just
removed the metal flat bar, you will find two yellow wires leading to an
electronic switch. Depressing this
switch allows you to slide the white plastic assembly beside it downward.
This may be necessary for the plastic assembly to clear the motor housing
as you separate the unit.
You can now very gently lift the plastic housing upwards and then towards the bottom to get around the motor.
Now you have successfully separated the unit, you can see the main drive belt. Take note on how this belt is routed. Look under the motor mount and you will see a white plastic spindle and a stainless steel spindle. The belt goes around the right side of both spindles, over the big wheel on the right, and under the big wheel on the left. (see diagram)
