MAINTENANCE
Wheels (Ø134mm - narrow)
Verify wear also on narrow Ø134mm wheels
located on the inside of rear Track System units,
especially on interior guidance strip. Replace
wheels also if rolling band narrows to a width of
17 mm or less -- (20 mm when new). Figure 32.
CAUTION: A wheel that is excessively worn will
not offer enough support for track guidance.
Figure 32
If internal plastic structure is visible (Figure 33-2)
-- (new wheel Figure 33-1), rubber coating is
worn away and wheel must be replaced. See
Figure 33.
Figure 33
Urethane cones (Stabilizers)
Check condition of urethane cones mounted on
stabilizer shaft. Replace both of them, if they
show oval wear on the bore, cracks or are
deformed. See Figure 34.
Figure 34
Track guide
Verify wear on Track guide by measuring width of
guide rails. If rail dimensions, illustrated in Figure
35, are less than 5 mm at any point along Track
guide, replace part. If guide is so worn that
concave shape is no longer visible, replace part.
Figure 35
CAUTION: An overly worn Track guide could cause
premature wear
and damage
on other guidance
components of the System.
