Wheel Wear
Inner Surface
Excessively worn wheels will
not offer enough support for
track guidance.
Inspect for wheel wear,
especially on the interior
guiding strips. Replace a wheel
if the inner surface
is
perforated
or if the width of the
rolling band has worn down to
less than 1.75 inches (45 mm).
Excessively worn wheels will
not offer enough support for
track guidance.
Inspect for wheel wear,
especially on the interior
guiding strips (1) and between
the wheel profiles (2). Replace
a wheel if the inner surface is
worn out or if cracks appear
between the wheel profiles.
Sprocket wear
Replace if < 3/4 in. (<19 mm)
Excessive sprocket wear could
lower track drive efficiency and
reduce system performance.
Measure sprocket wear as
illustrated.
Replace the part if
any measurement is less than
3/4 in. (19 mm).
