Just throwing out ideas. Cam bolt is a 10mm hex? That is a dumb design.

Use the belt you have and buy a new one for when you put it back together.

Impact and lever arm are different forces, sort of. That is why you can use an impact while a wheel is in the air and able to spin freely and you can't use a torque wrench. This should be similar. The tools you have will only allow you to apply a small resistance to the gear but you want to apply a larger force to the bolt.

And sometimes a few hits in the tightening direction will help break things loose.

I know I have a 10mm on a 3/8 drive, not sure about a 1/2" if you want to try it. Or use a 10mm impact socket with a cut off 10mm allen wrench.
