If the washer is top loading and the pump is under the motor, kind of right side up, it is similar to my Amana LW8203W2 and if so, here's how I did mine:
Need 5/6 and or 1/4 nut removers to do the job
Remove two drain hose clamps, remove 2 drain hoses
Remove 5 screws to the motor mounting
Move loose motor inward while removing belt from pully directly under tub.
Once removed, take motor/pump/belt out of washer and place it up side down
This next step needs a special star-shaped screw driver.
Remove the idler spring from the idler (strip of medal holding black wheel). Note position of belt before removal. .
With that, remove the 3 screws holding the pump to the motor.
Careful when you pry pump from motor as plastic may crack. GOOD LUCK
