I want to make an assemby consisting of 3 parts. A crank shaft and a crank pin that screw into threaded holes in a crank disk. How can I insert them and prevent them rotating in their holes but still allow the whole assembly to rotate around the axis of the shaft? Also how could I lock a flywheel on to the shaft so that whole assembly can rotate togeather?

Apply assembly constraints.

Mate workplanes is often a solution.

Use logical sub-assemblies.
