movement.
■ CAUTION: Renew bowden cable if damaged. See the correspond-
ing Maintenance Manual (Line Maintenance) for the
respective engine type, 912 Series or 914 Series.

3.6.3) Assembly and adjustment
Ascertaining the position of the servo motor:
See Figs. 78-13 and 78-14.
To ascertain the servo motor position, power-up the TCU.
◆ NOTE: After the automatic self test of the servo motor (12), put
the throttle lever into idle position to make sure that the
servo motor will remain always in position with wastegate
„closed“. The servo motor is self locking.
Position finding is absolutely necessary for correct
adjustment of the Bowden cable.
While assembling the rope sheave, interrupt the voltage supply to
the TCU or unplug the 2-pin plug connection (13). Risk of destroying
the servo motor if it is activated by the TCU during assembly.
Fit rope sheave as per detail A, Fig. 78-9 and secure with washer, lock
washer and allen screw M5x20 (10). The rope sheave has to be fixed
to prevent rotating of the output shaft when the rope sheave is
tightened. Tightening torque to 6 Nm (53 in.lb).
