Product review (4 stars): Removal problems associated with dryer motor
Once installed, this motor works just fine. Unfortunately, removal of the old motor was not as simple as the online video would suggest. The key is the separation of the blower fan from the rear of the motor. The fan is made from resin or plastic and has a raised square journal surrounding the threaded hole that allows the fan to thread onto the rear of the motor shaft. Using an appropriate size wrench, hold the square journal on the fan to prevent it from turning while using another wrench to turn the pulley retaining nut on the front of the shaft. As you turn the motor shaft, the fan is suppose to unthread from the motor shaft, The fan end of the shaft is left-handed thread so that the fan tends to remain tightly fixed to the shaft during operation.
Unfortunately, due to the type of material the fan is made from, when drying multiple loads of laundry, the fan becomes pliable and can actually get tighter on the shaft. When the unit cools, you'll find that the fan has become frozen to the shaft. Attempting to apply excessive force to rotate the shaft only serves to round-off the square journal on the fan making it impossible to remove. This happened to me causing me to have to remove the back of the machine, the blower duct & use a saws-all to cut the motor shaft so the motor could be removed. Truly a nuisance and a lot more work.
This, of course, is not the fault of the motor since the blower fan is not a part of the motor and when you order a new motor, you do not receive a new fan with it. The fan, if required, must be ordered separately. I believe this is the dryer manufacturer's design flaw. If the blower fan were made of aluminum or some other light-weight metal, rounding off the square journal would be far less likely.
