Not exactly sure what you are asking. The timing wheel is on the crank shaft. The crank also turns the chains that operate the cams, which in turn operate the valves. Pistons and such are a part of all the mix and the crank is what they are mounted to. The timing wheel is nothing more than a signal device for the spark.
This is the readers digest version, and the same with any engine that uses chains.
Is this what you were asking?
