NOTE
The location of the belt tensioner can vary, depending on the front
engine accessory arrangement.
Clean and examine for reuse
1 Inspect the drive belt for damage.
Transverse (across the belt) cracks are acceptable.
Longitudinal (direction of belt ribs) cracks that intersect with
transverse cracks are not acceptable.
2 If the belt is frayed, punctured, or material is missing, the belt
is unacceptable for reuse and must be replaced.
3 Inspect the belt grooves for:
•
Embedded debris
•
Uneven/excessive rib wear
•
Exposed belt cords
4 Inspect the backside of the belt for:
•
Glazing (high heat)
•
Embedded debris
•
Exposed belt cords
If any of the above conditions are present, the belt must be
replaced.
5 Examine the idler and drive pulleys for wear or cracks.
6 The dirt can be removed with a suitable tool to examine for
wear.
7 Clean, examine, and reuse all pulleys in the front end acces‐
sory drive if not damaged, rather than replacing. Pulleys dam‐
aged from embedded debris must be replaced.
