O-320 prop torque

I need to remove the prop on my Lycoming O-320 on my airboat to replace the alternator belt. What is the torque specs and the order to tighten the bolts? It is a three blade prop that is made of carbon fiber or something, black fiber, not wood.

My whirlwinds have the torque written on the plate. Don't take the small bolts out. Take the 5 larger bolts out and the prop comes off without changing the pitch.
