Use at least one mylar shim to contact bolt heads. (9) When shims are required for location of spinner support, select quantity and thickness so that spinner shell screw holes are misaligned with the rear bulkhead holes or nuts by 1/2 hole diameter. (8) For propeller mounting bolts with drilled heads, install lockwire (use aminimum diameter of 0.032 corrosion resistant steel conforming to MS20995C32) between pairs of bolt heads. The following formula should be used to determine what the torque wrench indicator should read in order to obtain the correct applied torque: (actual torque required) x (torque wrench length) -= Torque Wrench Reading to Achieve the (torque wrench length) + (length of the adapter) Required Actual Torque (7) Torque the mounting bolts/nuts in an alternating sequence to prevent the propeller from rocking on the engine flange.
