Wheel
Verify wheel wear especially on the interior guiding strip
(see Figure 24). If the internal plastic structure is visible, the
rubber coating is worn and the wheel must be replaced
(see Figure 25), or when the width of the wheel's rolling band
reaches 17 mm, (see Figure 26: 20.5 mm when new). A wheel
that is excessively worn will not offer enough support for track
guidance.
