Checking
1. Inspect the drive belt for proper tension and for the following:
•
Excessive wear
•
Cracks
NOTE: Minor, transverse cracks (across the belt width) may be acceptable. Longitudinal
cracks (in the direction of belt length) that join transverse cracks are NOT acceptable.
•
Fraying
•
Glazed surfaces
•
Proper tension ‑ 13 mm (1/2 in.) deflection, with moderate thumb pressure, on the
belt at the location that has the longest distance between two pulleys.

Replacing
IMPORTANT: If a belt is to be reused, it should be installed in the same direction of rotation
as before.
The belt tensioner is designed to operate within the limits of arm movement provided by
the cast stops when the belt length and geometry are correct.
