Washer making noise during cycles

I moved the washer out from the wall. unplugged washer, turned off water. Took off rear plate exposing pump. Disconnected hoses, using dry/wet vac to catch water. Took out three screws holding pump to base of washer and removed pump, belt slipped right off. Set new pump in place and put in screws. Connected hoses, put rear plate back on. Tilted washer back and installed belt on pulleys and motor. Turned on water, plugged in washer, started to wash clothes. Washer works fine and QUIET. I have yet to find the model number on my Maytag washer. I ordered the pump by sight (good pics).
