Have tried with out success to determine what is preventing the rotation of the crank in this assembly, assistance and explanation will be gratefully appreciated.
Main reason crank will not rotate is that the connecting rod is concentric with the cylinder. Only two rotational positions could be are top and bottom of piston stroke.
This is a future version file for me , but i see that you attached assembly only and we dont have any use of that. You need to attach parts also . (Use Pack and Go)
If your assembly has sub-assemblies you need to make them flexible
Thanks for that tip, however there are no sub assemblies in this assembly, all are individual parts.
We also need the part files to be able to debug the issue.

What is your address?
I will be over in a few minutes to copy the parts off of your computer...
call me at 510-793-7913, I am uncomfortable with giving out my address in this forum.

Ken Brunskill He was kidding (we do that sometimes on the forum to entertain ourselves - we are sometimes bored and always grumpy old engineers and designers after all.)
You'll need to include the parts if you want help. The zip file only contains the top level assembly.
That was not the top assembly, I am still designing this, so only had the parts that were pertinent to designing the next parts. Will be adding gears and levers as I progress.
I’m not sure about everyone else but when I open the zip file there was only one assembly in there and it was searching your C:\ for all the component parts.
Parts, Parts who needs parts, this ain't a game....
Here are the parts to the assembly that was in the original post.
The whole assembly moves. It is also at odd angle. There are two different methods used in putting assemblies together. One is to insert the first part so that it's front, top right planes are coincident with the assembly planes. It will come in fixed The other option is to mate it's planes to assembly planes.
If I fix your cylinder part, all the others are fully mates also. In order for the crank to rotate, the connecting rod has to be able to move back and forth in the cylinder. You really need the piston modeled and added to assembly. Mate the piston concentric to cylinder and concentric to hole in connecting rod.
Wayne, you’re a saint.
Wayne as in my email reply I sincerely appreciate your taking the time to point out the obvious point that I kept overlooking.
Paul, as with Wayne I appreciate your taking the time to look at this and point out the issue in such an unambiguous manner.
