Technical Flathead Crank pulley torque specs

Can someone please tell me what the crank shaft pulley should be to torqued to?

 

I never saw a spec for that. The size indicates it should be around 50 ft lbs.

 

That's it 50 ft pounds?

 

Good question.... Didn't find it in any books I have, either..... Anyone ?

Thanks Andy!!
