I have put a red oval around what I think is a govenor, can someone verify this for me? If it is...why would you use one of these types of devices? How does it work? Thanks, Chevman Click this link to see the manifold....or just look at the picture here....

On heavy-work trucks, this protects the engine from over-revving under high loads at low speeds. I believe that you are able to remove this device with no adverse side affects (except losing the over-revving protection).

Most all of these trucks are equipped with very low(slow)
Rear Ends. Won't take much over revving to spin a Rod bearing or worse.
A well maintained,good working Governor is a must.
Just my opinion.
The little wheel on the right of your picture should have a seal wire through it.
You rotate the wheel to increase or decrease Max. RPM.
Use a tach/dwell meter to set at factory spec's.
