AR41.10-P-0086P Measure Propeller Shaft Alignment With Electronic Angle Meter







NOTE:
- The vehicle must be on its wheels for the measurement
- The transmission mount and exhaust system must not be stressed during the measurement of the articulated angle
- Eliminate the stress if necessary
- On vehicles which are the subject of complaints due to drive line vibrations or roughness when accelerating, the cause may be a deviation in the propeller shaft-articulation angle from the specified value

DANGER:
- Lethal injuries are possible if vehicle slips off of lifting platform
- Align vehicle between the columns of the lifting platform and position the four support plates at the lifting platform support points specified by the vehicle manufacturer

1 Jack up and support vehicle
2.1 Remove bottom section of sound-proofing capsule
2.2 Detach lower engine compartment paneling
3 Remove front reinforcement brace below propeller shaft

NOTE: The exhaust shielding plate for the rear engine mount must not be detached from the reinforcement bridge for this

4 Prepare electronic propeller shaft articulation angle meter
5 Adjust propeller shaft articulation angle meter if necessary

NOTE: See device operating instructions for information about adjusting meter The articulation angle can be measured using two different meters

6 Measurement of absolute angle at transmission
- Vehicles with manual transmission or automated manual transmission (SEQ)
- Vehicles with automatic transmission

7 Measuring absolute angle at front and rear propeller shafts
8 Measure absolute angle at rear axle housing
9 Rear out front (41), center (42) and rear articulation angle (43) from the memory of the electronic propeller shaft articulation angle meter and correct if necessary

NOTE:
If the articulation angle has to be corrected, the necessary assembly operations are to be carried out.
- Front articulation angle from transmission to front propeller shaft (1 degree)
- Center articulation angle from front propeller shaft to rear propeller shaft (2 degrees)
- Rear articulation angle from rear propeller shaft to rear axle center assembly (3 degrees)
Carry out a check measurement again each time the articulation angle is corrected.
