TIGHTENING TORQUE
2,5 Kg/m 25 N.m
STEP 6.
Once the desired pitch angle obtained, slightly tighten the assembly screws of
the hub, those around the foot blade and then perform the same operation on
each of the other blades.
STEP 7.
Remove the adjusting tool from the propeller then perform a first tightening of the bolts manually.
Then, carry out a progressive tightening of all the screws by applying the correct torque with a torque wrench:
Mounting with a 912H spacer:
Assembly of the three-blade hub + Fixation of the
spacer (EI-912H-80, 100, 120):
(screw length adapted according the adaptor spacer
length and the starter flange on the propeller-shaft)
Propeller fixing: (or spacer if spacer > 80mm)
Screw CHC M8 & pin contact washer (screw length
adapted according the length of the spacer).
Use with dowel threaded on the engine propeller shaft
(Ex: For Rotax 912S, Screws CHC M8x130mm)
Mounting with an Adaptor spacer:
Assembly of the three-blade hub
Fixation of the Adaptor spacer:
Screws AN6 or AN8
(screw length adapted according the
adaptor spacer length and the starter
flange on the propeller-shaft)
Propeller fixing screws:
SAE1: Screws DUC AN6-52
SAE2: Screws DUC AN8-52
Remark: It is imperative to use a spinner when using propeller FLASH-R.
The mounting plate of the spinner can be placed before or after the spacer
adaptation. It is necessary to adapt the mounting in function of its position
