This is a good replacement OEM motor for my 30 + years old dryer.
The instructions were reasonably clear.  Note that this motor will retrofit many models so it may require some minor customizations (instructions include them all in a brief manner).
The metals slotted bands which hold the motor in place are tricky to remove and you could get hurt from their sharp edges. Using a screw driver to  stretch the bands to remove or secure them on their place can cause the screw driver to slip and cause serious cuts.  A nut driver with a small socket to hold the curled edge of the metal bands worked better since it will not easily slip off the metals band ends.  But, be careful in this step.

I made one wiring error which gave me a lot of grief.  The instructions asked to remove and discard a short blue jumper wire between the 'overload switch' and the 'motor switch' (which has multiple male spade terminals).  I realized that I had mistakenly connected the 4A blue main harness wire (from the dryer) to the terminal 4  on the motor switch side (a 1/8" spade connector) where the rest of the dryer harness connections were made to connect.  The right thing to do is to connect the 4A blue main harness wire (from the dryer) to the overload switch side which has a wider spade (1/4") connector.  (The dryer harness had a female 1/4" spade connector - which mated perfectly). Once having fixed the connection, it worked perfectly.  (I wish the FSP instructions were a bit more clear).

To check correct connections, do the following at your own risk and only if you understand how to wire and understand electrical connections.  Do not put in the drum and belt.  Disconnect main plug of the dryer.  Complete all dryer harness to motor connections, secure motor with its bands.
Do either Step A or B:
Step A:  Bypass the door switch (Note: One side of the door switch wire has a single wire running to a single spade terminal.  This is the hot wire.  The other side of the door switch has two spade terminals and two wires.  Depressing the door switch (when dryer door is closed) allows the motor to turn and shuts off the drum light.  On opening the dryer door, the non-depressed switch shuts the motor and turns on the dryer light).  With door switch disconnected from all three wires, find which of the two spade connectors shows continuity to the single spade connector on the other side of the door switch when the door switch in its depressed position (This will be the terminal whose wire allows power to the motor). Short the door switch hot wire to this wire.
OR, skip Step A and do Step B:
Step B:  You can remove the door switch from the dryer panel and make the connections normally.  Ensure insulation of the door switch terminals from everything else.

Leave nothing exposed to making grounding shorts to dryer body.  Check all connections carefully and out in the dryer plug.
If you did Step A, then the motor should run only upon hitting the 'Start' button and stay on.
If you did Step B, then you will need to additionally depress the door switch while making sure that the door switch terminals do not touch you or anything else. Again,ensure insulation of the door switch terminals from all else.  Motor should run only upon hitting the 'Start' button and stay on.  Releasing the door switch button should turn it off.

The motor tends to have a bit of a howl when warm.
