WARNING:
Please note that this type of intervention might not always be sufficient to solve the problem, especially
after the first hours of flight due to the major settlings that happen during running in. In such a case,
the operator may slightly stretch the pre‐rotation cable, as described here below
3.2.1
CABLE STRETCHING PROCEDURE
(See Fig. 3.2/1 ‐ 3.2/5)
1.
Before starting this operation, verify that the engine's ignition key and push‐button are in OFF position
and that all the breakers are switched OFF.
2.
Completely screw the adjuster pn 127 of the sheath pn 104 of the pre‐rotator cable pn 1,5 x 3.900.
3.
Loosen the cable retainer pn 107 located close to the lever (1) of the belt tightener (5) of the pre‐
rotation assembly pn 117.
4.
Pull the pre‐rotation control cable pn 1,5 x 3.900 and tighten the cable retainer pn 107. This will modify
the position of the belt tightener (5), further stretching the belts A28.
5.
Verify that the brake shoe (2) of the belts A28 really touches the belts when the pre‐rotation activating
lever pn 415 is in rest position. If this is not the case, release the bolt M5x40, then re‐position the shoe
(3) as indicated in the figure and tighten the bolt M5x40 again.

Shimming of the pre‐rotation assembly pn 117 will be required if the above described procedure generates
interference between the lever (1) of the belt tensioner and the support pn 120, or if the play between the belts
A28 and pulley pn 124 is still too big to allow to reach the parameters indicated in the efficiency test diagram. The
operator will have to shim the pre‐rotation unit pn 117 so as to tighten the belts and remove the play.
