CAUTION
The assembled rotor system can be damaged irreparably if handled incorrectly.
If the rotor system is lifted in a wrong way, its own weight may overstrain the
material.
8.15.2
Disassembly of the Rotor System
1. To disassemble the rotor system, place it upside down onto a clean surface or stands
to support the rotor at approximately 2 m from the hub (so that the system is at the
design coning angle of 2.4deg per side).
2. Loosen locknuts (6) on the first blade by counter holding the corresponding bolt head
to prevent it from turning inside the blade holes.
3. Push out all fitting bolts (4) without any force, but use no more than a gentle tapping if
necessary. Tilt the rotor blade up and down to support easy removal of the bolt.
Note that fitting bolts have different shaft lengths.
4. Carefully pull the rotor blade out of the hub (1) in radial direction and take off the
clamping profile (2).
5. Repeat step 2 to 4 on second rotor blade.
6.
Do not disassemble the rotor hub!
7. Store and transport rotor blades, clamping profile and rotor hub only in air cushion foil
or using other suitable means to prevent bending or surface damage.
1 – Rotor hub
4 – Fitting bolts (as depicted)
2 – Clamping profile
5 – Washer (12 ea.)
3 – Rotor blade
6 – Lock nuts (6 ea.)
