Torqued Propeller Mounting studs to 65 ft-lbs per Table 3-1 and Fig 3-2 ( Step 1 = 40 ft-lbs, Step 2 = 65 ft-lbs) in Hartzell Prop Owners Manual #115N.   Safety wired and applied Torq Seal.  Adjusted alternator belt tension per Maint Procedures Sect 5, page 5-8 in Lycoming Op Reference Manual for IO-390 series.   Set by slip torque method to 145 in-lbs (midway between 132 to 156 in-lbs for New belts.

Works well, but wow is this tool expensive.
