The motor cover and stator are secured to the motor using the original screws that come with the motor.

Motor is a Samsung DE31-00029H.  You can also use a DE31-00029K or DE31-00029J or any other 29 motor.

Solenoid is a JF-0826.  I use the 24V one, but other voltage rated ones work as well.  Return spring needs to be stretched a little bit so it has enough tension to reopen against the rotor suction.

10 gram slotted weights (16x)

To secure the weights, simply push them into the bottom of the rotor.  They should just slip right in.  If needed, you can tap them in with a hammer.  These are made of steel, so it should be alright to take some hammer taps.

Put a set screw in both top holes on the shaft coupler.  leave the bottom two screw holes empty.  Then tap the coupler into the rotor from the bottom with a plastic mallet or plastic screwdriver handle. 

Make sure the set screws are lined up with the access cutouts in the rotor hub.  Don't use a hammer, you can damage the soft aluminum.
