Put the chain on the bottom gear and then the top gear, then install the top gear on the camshaft.

Put the old gear back on if you have to. Check for burrs on crankshaft but if the old gear fits on and its ok then leave it on.*** I have replaced a ton of these timing chains and I never replace the lower gear.
