RE: Cox Reed Valve FAQ
KE,
The crank is pressed onto the prop driver. No big deal to remove though, just screw on the prop bolt and give it a good couple hits with a hammer with the back of the case resting on a hard surface. I guess a piece of sheet brass would work for the thrust washer. I do believe the factory uses stainless steel. To put it all back together get the prop driver started back onto the crank by hand and mount a prop on it and tighten the prop screw and it will pull it all back together. The crank has a shoulder that the prop driver stops against.
LAter,
