- Overhead Cam
-
- An overhead cam is
- mounted on top of
- the cylinder head,
- hence the name.
- The cam is driven
- from the crankshaft
- using a belt or
- chain. Because the
- camshaft rotates at
- only half the speed
- of the crankshaft,
- the crankshaft
- sprocket must have
- half the teeth of
- the camshaft
- sprocket.
