3. Remove and discard split pin and unscrew the castellated nut (5). The rotor system
has to be tilted onto the black rotor teeter stop.
4. The teeter bolt (1) has to be extracted by using only the hand, not a hammer. If
needed tilt the rotor blades carefully onto the teeter stop, in order to prevent the bolt
from jamming. Make sure that the rotor stays level in the teeter axis, if not the teeter
bolt will damage the Teflon coated bushes, while being pushed out.
5. A supervised second person has to hold the rotor system in flying direction.
6. Lift the rotor system carefully out of the teeter tower and be aware of the position of
the shim washers (2). Their thicknesses may differ and it is essential that they are
reinstalled on the correct side! They are marked with dots to identify the correct side.
7. Remove the rotor system to one side by letting it rest on your shoulder and take care
not to collide with stabilizer or propeller.
8. The shim washers and the teeter block in the hub are marked on each side with one
or two engraved dots. Directly after the disassembly the shim washers need to be
fixed on their respective side with cable ties to prevent loss.
9. The rotor system must not be placed on a dirty or grainy surface, as the blades can
scratch and damage easily. The best way is to place the rotor blades centrally onto
two stands, supporting the rotor at approximately 2 m distance from the hub.
1 – Teeter bolt 4 – Split pin
2 – Shim washers (2 ea.) 5 – Castellated nut
3 – Outer washer
Handling of the Rotor System
Do not lift or support the rotor system at its blade tips as the bending moment due to the
weight of the hub assembly may overstress the blade roots. If possible, handle with two
persons while holding approximately in the middle of each blade. When supporting the
system use two stands each positioned in about 2 metres distance from the hub.
