The plastic pulley on the motor is badly worn on my Admiral (Maytag)
Washing Machine (basically starting to split apart). I have ordered a
new pulley but a bit worried I won't be able to remove the old one
since I see no obvious way to do this minus brute force.

All plastic? Break/cut/chip it off.

If it has a stuck metal hub, get a cheap gear puller tool from the auto
parts store or Harbor Freight. DO NOT apply axial force to the motor
bearings by hammering on the shaft.
