6. If there is a large amount of contamination on the
radiator fins, use detergent with tap water to clean fins,
and rinse thoroughly.
V-BELT (DAILY)
Visually examine the V-belt (Figure 54) and determine if it
is full of tiny cracks, frayed, has pieces of rubber missing,
is peeling, or is 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 above wear conditions,
replace the V-belt immediately.
