Poly-V Belt Inspection
Application:
9000 Models with B202 Engine
Figure 1.
Routine inspections of the multi-groove (Poly-V) belt on 9000 models may reveal cracks in the belt ribs. Such cracks occur under normal wear and tear
and do not affect the performance of the belt. These minor cracks should not be considered a problem that requires a belt replacement (Figure 1).
Figure 2.
The following guidelines should be observed to avoid the cost of replacing belts unnecessarily.
1.
A belt should be replaced if it is damaged, frayed or a worn area exceeds 5 mm along the length of the V groove (Figure 2).
2.
Belts that slip when correctly tensioned should be replaced.
Note
Saab does not recommend the use of a "belt dressing" for the purpose of quieting a squeal. If a belt is properly tensioned and free of contaminants
(oil, ATF, etc.) but continues to squeal (slip) then the belt should be replaced.
