5.1 Apply Tef-Gel (or equivalent) to the internal spline of the Propeller Drive Shaft. Align the Propeller Drive
Shaft with Gearbox Output Shaft Spline and push the Propeller Drive Shaft onto the Gearbox Input
Shaft. [Tools: By Hand Only]
INFORMATION:
The LH (left hand) thread of the Propeller Hub ensures that it is self-tightening
while the Propeller is driven. With the fine thread extra caution must be taken not to cross thread
with that of the Frame. To find the beginning of the thread, slowly rotate the Hub clockwise until
you can feel it step off the first thread. Now rotate anti-clockwise to fasten. No torque value is
specified but strong hand tight will be sufficient as the minimum torque required.
5.2 Apply Tef-Gel to the thread of the Propeller Hub. Fasten the Propeller Hub screwing it into the frame by
rotating anti-clockwise as this is a LH thread. [Tools: 40mm Open Wrench]
