The 6.2L has a forged steel carburized camshaft for durability. (Figure 2-27). There are 5 bearing journals which position and support the camshaft. The camshaft has 16 lobes. There is an eccentric lobe immediately rear of the number one journal. This eccentric changes rotary motion of the camshaft to linear motion of the fuel pump push rod, thus the mechanical fuel pump is operated through a push rod off the camshaft.
There is also a helical gear at the rear of the camshaft, this gear mates with another gear which drives the vacuum pump and the oil pump.
