If laser measuring systems are used, care must be Calculation of the toe-in and toe-out settings:
taken to ensure that the axle is aligned horizontally
with the base in order to obtain a correct measure- A1 - B1 (mm)

The operating and setting instructions of the system
manufacturer must be adhered to! Positive value = toe-in
Negative value = toe-out

in/toe-out value of the axle and must be within the
permitted tolerance range.

R Reemmaarrkkss::

The tracking tolerances defined by BPW must be
maintained. Only by maintaining these tolerances
can low-wear operation of the vehicle be assured.
The tracking values are set for steered axles at the
Horizontal
axle position factory and the steering rod must not be adjusted.
Tolerances for rigid or steering axles can be down-
loaded from the BPW website (www.bpw.de/down-
load/News), or found in TE sheet TE-4120.0.
