Here is the info on your pump:
Part Details - MAYTAG Pump, part number: AP3873050
Over all not super hard, you will have to pull the front panel. Remove the belt and then pull the pump and motor out as a assembly. Remove the 3 screws holding the pump on, clean any black residue off the motor shaft, the reinstall in reverse order. Make sure you remember where everything goes! Especially the belt routing and idler arm position!
