M16 (C) TANDEM TRAINER
MAINTENANCE MANUAL
3.11.7
INSTALLATION OF FORK pn 426
(See Fig. 3.11/3 and 3.10/5)
1.
Insert the lower bearing pn 4T 32004 X (for all the gyroplane versions up to serial number
16053404) on the stem of the fork pn 093; or insert the bearing 4T 32005 X (from serial number
16053404 (included) onward) on the stem of the fork pn 426;
2.
Insert the stem (6) in its seat, inserting the upper bearing (same as the lower bearing) on the stem;
3.
Screw and tighten the lock nut pn KM4;
4.
Screw the control block pn 277 till the 5mm diameter fixing holes are lined up;
5.
Insert and tighten the bolt M5x42 that fixes the block pn 277 to the stem (replacement of the fibrelock
nut M5 is recommended);
6.
Tighten the lock nut pn KM4 against the aluminium control block pn 277 (unscrewing the lock nut from
the stem). This serves to avoid possible plays of the control block pn 277 on the stem;
7.
Insert the spacer pn 077, the end (1) and tighten the bolts M6x80 that fixes the rods pn 076 of the pedals
(replacement of the fibrelock nuts M6 is recommended);
8.
Install the nose wheel (5) through the following connection: fork ‐ spacer pn 094 (or pn 427) ‐ wheel ‐
spacer ‐ fork (6);
9.
Tighten the pivot of the wheel as explained in the paragraph "assembly of nose‐wheel and fork" (3.11.2);
10.
Insert and tighten the cables through the turnbuckle (see paragraph 3.10.4.3, "Installation of the cable");
11.
Put safety wiring (2) on the turnbuckle (See Fig.3.10/5).
3.12
CHECK OF TIRES
(See Fig. 3/12)
WARNING:
The M16 (M16C) gyroplane tires are made of 6‐ply tread with air tube. The nominal dimensions of the
tires are listed in the table at the end of the paragraph. Tires need to be checked at the beginning of
each season, to check the wear and above all the correct inflating pressure. Please remember that an
incorrect inflating pressure will compromise the road holding and direction keeping of the gyroplane
during taxiing and its overall trim. Furthermore, an unusual wear of the tire will also increase the risk of
punctures.
3.12.1
FRONT WHEEL CONTROL PROCEDURE
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.
Lean the gyroplane on the tail, so that the nose is up and the access to the front tire is easier;
3.
Verify the wear of the tread and check that there are no radial cracks on the rubber;
4.
Remove the inflating valve cap;
5.
Measure the tire pressure (4, fig. 3.11/3) and correct it according to the inflation pressure table (see
paragraph 3.11.1);
6.
Close the valve with its cap.
