            Ed,
        I would highly recommend you get a copy of the overhaul manual for     your engine to use as your primary reference.  For every nut and bolt     on the engine, the manual will either list a specific torque or     default to a table of 'standard torque values'.  If you blindly apply      standard values based on the fastener size, you may end up damaging     something.  In most of the non-standard cases I have encountered thus     far, the specified torque was lower than what I would have applied     given the fastener size.  The same goes for the bolts holding the     Hartzell Prop hub together.  They are less than a standard torque.
    Manuals and any other Lycoming literature can be ordered directly from     Lycoming at a very reasonable cost.
