Hi,

This process requires special tooling. You need them to prevent the camshafts from moving and properly setting them.

If you look below, I attached the directions for installation from my manual. Take a look through them and let me know if you have questions,

Take care,

Joe

Thank you, is it possible to find out what is the distance of the internal part (in millimeters) on this device?

Hi,

I'm not sure what you need. Are you talking about the clearance between the pistons and valves? If so, that isn't something I have.

Let me know.
