V-belt Cover Removal

To inspect the V-belt, remove the three bolts that secure
the belt cover to the frame as shown in Figure 8.
Figure 8. V-Belt Cover Removal

V-belt inspection

Visually examine the V-belt (Figure 9) and determine if it
is full of tiny cracks, frayed, has pieces of rubber missing,
is peeling or otherwise damaged.
Also, examine the belt and determine if it is oil soaked or
"glazed " (hard shiny appearance on the sides of the belt).
Either of these two conditions can cause the belt to run hot,
which can weaken it and increase the danger of it breaking.
If the V-belt exhibits any of the referenced wear conditions
replace the V-belt immediately
