Drive Belt
Inspection
Visually inspect the belt. Check the belt for
intersecting cracks. Transverse (across the belt
width) cracks are acceptable. Longitudinal (direction
of belt length) cracks that intersect with transverse
cracks are not acceptable. Replace the belt if it is
frayed or has pieces of material missing. Refer to
Adjustment and Replacement (Section A).
Cooling Fan
Inspection
WARNING
Personal injury can result from a fan blade
failure. Never pull or pry on the fan. This can
damage the fan blade(s) and cause fan
failure.
NOTE
Rotate the crankshaft by using the engine
barring gear.
A visual inspection of the cooling fan is required
daily. Check for cracks, loose rivets, and bent or
loose blades. Check the fan to make sure it is
securely mounted. Tighten the capscrews if
necessary. Replace any fan that is damaged.
