Where can I find ...?

It turns out that I want to pass the F8M engine of the Renault Express to 3D.

The problem: the measures.

Is there any manual or book of the diesel engine f8) pieces ??

I need to verify certain parameters with a mechanical stress program of the pieces, simulation.

If you know what is called or where I can find a certain document, the F8M workshop manual passes, it turns out that the workshop and exploded manual do not come to me to lift it in 3D.

I think it would have to ask the company not?, Already before the pieces were created, measures had to be taken (their limit) for their manufacture.

Thank you very much, and greetings.
