Inspection And Replacement Of Front Suspension - Magni Gyro M16C Ordinary Maintenance Manual

3.11 INSPECTION AND REPLACEMENT OF FRONT SUSPENSION
(See Fig. 3.11/1 ‐ 3.11/3)
3.11.1 ENTIRENESS OF TIRE
The tire must satisfy several basic requirements to avoid inopportune punctures or lowering of the pressure:
•
The wear of the tread (1) must not be excessive.
•
The tire must not show abnormal abrasions (2).
•
The tire (3) must not show radial cracks, which are symptoms of ageing.
It is possible to visually check all these requirements. The correct inflation pressure (4) helps in reducing the wear
of the tire. Therefore we strongly recommend checking it carefully and regularly, at least at the beginning of each
new season.
The correct inflating pressure for the nose tire is 1,6 ‐ 1,8 bar.
Please remember that taxiing on hard surfaces or asphalt increases the wear of tires. Under such conditions, we
recommend to check the tire and its pressure more often.
3.11.2 FIXING OF NOSE WHEEL AND FORK
(See Fig. 3.11/3)
The nose wheel (5) and fork (6) are assembled through the connection of the bolt pn M12x160 and the fork pn 093
(for gyroplanes with serial number till 16053404) (or pn 426) and the spacer pn 094 (or pn 427) and the wheel (5).
Tightening and blocking the wheel is done with a fibrelock nut M12.
The tightening action of the bolt M12x160 must be adequate, so as to avoid compression of the bearings 6201‐LU
of the wheel hub and allow complete freedom of wheel rotation. At the same time, the wheel must not have any
lateral play on the fork, which could cause vibrations to the entire system.
3.11.3 ENTIRENESS OF FORK
The fatigue of the front fork pn 093 (or pn 426) can generate its deformation. Deformation is a symptom of hard
landing or of take‐off and landing on very rough surfaces. Periodically check the fork so as to prevent excessive
deformation or failure of the fork stem.
3.11.4 CHECK PROCEDURE
(See Fig. 3.11/3 ‐ 3.11/2)
The fork check parameter consists in having a 90° angle between the main structure's spar (7), which supports the
bearings 4T 32005X that allow the fork's movement, and the plane created by the fork.
