Having problems with your 1993 Chevrolet Lumina ?
Flats on the camshaft
\015 I would like to know what flat is? I don't need a manual or a link to a repair site, I just want to know what a "flat" is. If you do NOT KNOW what a flat is, please do not respond.\015
Flats on a camshaft usually refer to the flat sections the manufacturers provide that you can put the correct size open end spanner over to hold the cam in the correct position when setting up the cam timing. Often the valve spring pressure tries to rotate the cam into the wrong position for setting up the chain or belt, and that's why they have these flats. That's the only use of that terminology that I'm aware of, hope it helps.
