18.2.1
Mounting the manual rotor lock
1.
Turn the hub until the highest point points up and one of the blade bearings points downwards.
2.
Lock the rotor with the hydraulic rotor lock or mount the three centering mandrels using 3 x 2
M20x40 from in front of the hub flange and into the locking holes of the main foundation.
3.
Place 16 x M42 bolts (782139) 5 on each side and 6 in the top.
4.
Insert 16 shims (782142) so the bolt is placed in the slot and the shims. Use a small hammer
for mounting to ensure there is no space between the shim and the hub/main foundation.
5.
Screw on the special nut, with washer underneath so it hits the hub flange.
6.
Tighten the yellow M16 special bolts (782141) following this procedure:
Tighten the 8 M16 bolts to 70Nm. Then tighten the 8 M16 bolts to 140Nm in a circular way and
proceed with this operation with the first 3 bolts again, so you at the end have tightened 11
bolts to 140Nm.
