NOTE
The nuts retaining the teeter bolt to the hub bar should be of the BinX type, in
order to maximise the clearance to the teeter stop plate.
8.15.3 Assembly of the Rotor System
1. The rotor blades, clamping profile and rotor hub are labelled with an engraved serial
number.
2. Insert the first rotor blade carefully into the clamping profile. Make sure that all serial
numbers match.
3. Fit the rotor hub side with the according serial number to clamping profile and blade.
Insert fitting bolts without using force so that the bolt end is on top when the rotor
system is installed. For re-identification and correct installation position the shaft
length is provided in the figure above. Example: 40/12 means shaft length 40mm.
4. Position the washers and the locknut and
hand-tighten all nuts to close the joints.
5. Position the rotor onto two trestles, 4m
apart. This will allow the rotors to sit at the
correct coning angle. A shortened trestle
(approx. 80mm shorter) located under the
hub bar will set the angle correct for easy
fitment of the second blade.
6. Repeat steps 2 to 5 for the second rotor
blade, such that the rotor sits on the trestles
with the hub midway between the trestles.
7. Attach a taut thin line, such as fishing line, between the blade tips, in the same
position at each tip. Slipping the line between the end cap tail and the blade enables
accurate positioning.
8. Remove the centre trestle, and raise the centre of the hub bar. Watch to see where
the line is with respect to the grease nipple. Adjust the blade position in the hub
assembly within the bolt freeplay to move the line as close as possible to run directly
over the grease nipple.
9. Torque-tighten nuts with 15 -25Nm from the inside to the outside, using a torque
wrench. When doing so, counter-hold bolts to prevent any damage the hub and blade
holes.
WARNING
It is important to fit the correct length bolt in the associated hole! Fitting the
wrong length bolt may result in insufficient safety protrusion through the
nylock nut, or that the nut jams on the shank of the bolt before the joint is
properly tightened.
