Undue mechanically transmitted noise or vibration
 Noise or vibration transmitted down the shaft
– suspect a loose air rotor. Grasp an air blade and rock the rotor to check if there is
any relative movement between the air rotor and the alternator shaft. If play is felt,
remove hub parts and re-build, fitting a new hub liner.
 Correct fit of nose cone
– check that the nose cone is not catching on the alternator housing.
 Air blade damage
– check that the blades are not damaged or chipped. This may put the rotor out of
balance. Replace air blades as necessary.
 Tail bolts
– check tail bolts are tight.
 Noises from the alternator
– rotate the air blades slowly and listen at the alternator housing. Grating or
scraping noises indicate a fault within the alternator.
