O-320 prop torque

[madtrapper]

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.

You may need to get a protractor and torque wrench if you don’t already have them

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.
