Measure absolute angle at front and rear propeller shafts - AR41.10-P-0085-02SX

The vehicle must be on its wheels for the measurement. All four angles should be measured in succession without interruption.

An angle that has already been measured can be measured a second time if required. To do this, with the Measurement menu displayed, press the STEP button repeatedly until the display indicates Ready to measure the relevant angle.

Measurement - Angle 2: front propeller shaft 

1. Clean contact surface for adapter for transmission (021) on front propeller shaft (1).
2. Fit adapter for transmission (021) to front propeller shaft (1) (magnetic).
3. Align adapter for transmission (021) horizontally in transverse direction using spirit level (021a).
4. Place sensor (020a) on support plate of adapter for transmission (021).

   The spiral cable (020b) of the sensor (020a) must point in the direction of travel for each measurement. Otherwise the measurement will be inaccurate.

   Measurement - Angle 3: rear propeller shaft 

7. Clean contact surface for adapter for transmission (021) on rear propeller shaft (2).
8. Fit adapter for transmission (021) to rear propeller shaft (2) (magnetic).
9. Align adapter for transmission (021) horizontally in transverse direction using spirit level (021a).
10. Place sensor (020a) on support plate of adapter for transmission (021).
