Information
General procedure for wheel alignment
Perform wheel alignment using an electronic wheel alignment tester. Measurement procedures should be taken from the operating instructions for the
wheel alignment tester used.
In order to exclude erroneous measurements, the following preconditions must be met before alignment and the following points should be given
special attention:
Unladen weight of vehicle according to DIN 70020, i.e. vehicle in ready-to-drive condition with full tank and including tools but without driver or
additional weights.
Ball-joint and wheel-bearing play in order (wheel-bearing play cannot be adjusted).
Tire pressure in accordance with regulations, fairly uniform tire tread.
Quick-clamping holder with adapter (for the measured-value pickups) correctly secured to the wheels.
Use self-centering quick-clamping holders to secure the measured-value pickups on the wheels. Any previously used quick-clamping holders that are
available can also be used.
The self-centering quick-clamping holders are positioned centrally (with the claws first) in the center of the rim and are tautened in the rim by turning
the straining ring (clockwise).
Self-centering quick-clamping holder
Receiving surfaces for the quick-clamping holder on the wheels and the adapter surfaces must be clean and flat. Always check the levelling surface on
the wheels precisely in particular before fitting the quick-clamping holders.
Strictly comply with maintenance intervals for measuring equipment and measuring platform. If the levelling of the measuring platform or measuring
station is done in-house, levelling equipment is required. A spirit level is not adequate.
