There are wires connecting the front panel to the control board at the back, and I don't want to bother with those, so I just disconnect the clip holding them in place and leave them attached.
Then I lift the front panel off and lean it up against the side of the machine.
The door opening of the front panel normally supports the drum, and since I removed that front panel, I grab a nearby hiking boot to support the drum while I remove the old drive belt. I have to press against the tension pulley to get enough slack to slip the belt off the drive shaft.
And then I pull the drum out.
