What's up with that spring style sprocket on the cam gear?
It's called a "scissor gear" and it's used to remove any backlash from the gears to quite the gear noise generated by the fuel pump piston loading and unloading the gears (backlash)

Looking closer at that cam gear it actually has two sets of gears. One contacts the crank gear and the second contacts the cp4 gear. The cp4 gear looks to be aluminum?
