If the slip ring has turned or it is not securely fastened, i.e. is not in the middle position, adjust the slip ring as follows: press the spring (F) and turn the slip ring left and right until it stops. Count the total number of revolutions and divide it in half. From the stop, turn the slip ring half the number of turns until the marks match (1). lower the spring (F).
Check that the direction indicator lever is in the middle position, otherwise the cams may be damaged when putting on the steering wheel.
Put the steering wheel on the splines of the shaft so that the marks applied during the removal coincide. When doing this, make sure that the fastening pin (1) entered the recess (2).
