Before installing a propeller, the propeller shaft and threads should not be checked for damage.
True
False
Boss and hub flange faces should be checked for cleanliness, to ensure that maximum friction will be obtained.
True
False
When assembling the hub to the shaft, it is usually recommended that an anti-seize compound should be applied to the threads, and engine oil to the shaft. Where cones are fitted, these should be clean and dry.
True
False
The angular position of the propeller on the hub is not important, unless the engine is likely to be started by hand swinging
TRUE
FALSE
The attachment bolts should be tightened evenly, and in any sequence, to the specified torque.
TRUE
FALSE
when the propeller is rotated the blades should track within 1/4 inch of each other, but a wider tolerance may be permitted on repaired propellers, provided that no vibration is evident during engine runs.
FALSE
TRUE
After engine runs to check the reference RPM, the propeller attachment bolts and the hub retaining nut should be checked for tightness, and re-locked.
TRUE
FALSE
It is recommended that the bolts should also be checked after each of the first few flights.
TRUE
FALSE
in Fixed Pitch Metal Propellers Installation, these are used to locate the propeller on the spacer or propeller shaft flange, and these should be a tight press fit in the holes.

False
The engine should not be ground run after installing the propeller, to check for vibration and determine the engine speed obtained at full throttle.
True
False
