3. Unscrew the 6 screws M5x12 that fasten the front footboard pn 429;
4. Remove the front footboard pn 429;
5. With a dial gauge (9) check the existing angle between the keel spar in A01 position (see fig. 3.11/1) and
one of the vertical arms of the fork;
6. Reposition the footboard pn 429 and fasten it to its seat with the screws M5x12;
7. If the control parameters are not within the allowed tolerances, the fork pn 426 must be replaced.
3.11.5 REPLACEMENT OF FORK pn 426
(See Fig. 3.11/3)
1. Before starting verify that the engine's ignition key and push ‐ button are in OFF position and that all the
breakers are switched OFF;
2. Remove the safety wire (2) from one of the turnbuckles pn MS 21251 ‐ B3S of the rudder pedals cable (4)
(see fig. 3.10/5);
3. Completely slacken the turnbuckle pn MS 21251 ‐ B3S so as to avoid any tension from the cable (4) on the
pedals pn 071;
4. Using two 10 mm wrenches, loosen and remove the two vertical bolts M6x80 that fix the control block pn
277 of the rudder pedals;
5. Using two 8 mm wrenches, loosen and remove the screws M5x42 that fix the control block pn 277 to the
stem of the fork pn 093 (or pn 426);
6. Unscrew the control block pn 277 from the stem;
7. Lean the gyroplane with its nose up, so as to be able to work comfortably on the front fork. Make sure its
equilibrium is stable. Support the gyroplane so it cannot drop back on the nose. As the wheel has been
removed for replacement, in case the nose would fall, it would crash on the ground, thus damaging the
lower part of the fuselage;
8. Unscrew and extract the screw M12x160 that fix the front wheel to the fork, then remove the wheel;
9. Supporting the fork pn 093 or 426, loosen and remove the lock nut pn KM4;
10. Extract the fork from the bottom and remove the conical bearings as described below;
11. Extract the bearing 4T 32004 X (for all the versions up to serial number 16053404), from the stem of the
fork pn 093; or remove the bearing 4T 32005 X (from gyroplane serial number 16053404 (included)
onward) from the stem of the fork pn 426;
WARNING:
If the deformation of the stem is too important and it is impossible to extract the indicated bearings, or
if this operation could damage them, these bearings must be replaced.
12. Clean both bearings with solvent and remove residual grease, dust, sand or soil;
13. Grease the bearings again (recommended grease: SHELL DARINA R2 or equivalent). Carefully press the
grease between the rollers.
3.11.6 PREPARATION OF SPARE FORK
The spare fork (6) will be supplied with pre ‐ drilled holes (Ø5.0 mm) in the stem and with its own calibrated lock
nut pn KM4. Before installing it, it is suggested to screw the lock nut KM4 on the stem, so as to check the
entireness of the thread M20x1. Last, previous to the installation, remove the paint from the bush (10) where the
axle M12x160 of the wheel is housed, so as to make its access easier during assembly.
