INSTALLATION OF FLEXIBLE SHAFT pn 118
(See Fig. 3.1/1 ‐ 3.1/5)
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.
Hang the sheath pn 119, which is still fixed to the rotor head (4), vertically.
3.
Insert at least one third of the flexible shaft pn 118 in the sheath, starting from the bottom towards the
top.
4.
Collect the excess of grease that does not enter the sheath.
5.
Extract the shaft pn 118 from the sheath and grease it again with the collected grease in excess.
6.
Repeat the operations indicated in points 2., 3. and 4. three or four times, inserting the shaft pn 118 into
the sheath pn 119 for a longer length each time so as to guarantee a correct greasing of the upper part of
the flexible shaft pn 118, too.
7.
When the flexible shaft pn 118 is completely inserted in the sheath pn 119, carry this sheath to the pre‐
rotator unit and insert the first part of the flexible shaft pn 118 into the square hole of the unit pn117.
8.
Climb a ladder so as to reach the upper part of the Bendix gear unit pn GR03.
9.
Using a key, rotate the socket head screw M6x20 clockwise so as to facilitate the insertion of the square
ends of the shaft pn 118 in their respective seats (upper (5) and lower (6)).
10.
If the rotation of the Bendix gear pn GR03 done with the 6 mm key corresponds to one rotation of the
pulley (7) of the pre‐rotation assembly, this means that the shaft pn 118 is correctly fitted in its seats (5
and 6).
11.
Insert the sheath pn 119 in the pre‐rotation assembly.
12.
Fasten the sheath pn 119 to the pre‐rotation assembly pn 117, tightening the M6x16 bolts and paying
attention to the spacer washers (3).
13.
Block the control stick (2) in all‐forward position.
14.
Position the sheath pn 119 on the support pn 193.
15.
Fit and tighten the clamps pn 4B‐25‐45;
16.
If the pre‐rotation pulleys or V‐belts are dirty with grease, carefully clean them with gasoline or solvent.
