8) INSPECTION OF COOLING FAN
Personal injury can result from a fan blade
failure. Never pull or pry on the fan. This can
damage the fan blade and cause fan failure.
Rotate the crankshaft by using the engine
barring gear.
A visual inspection of the cooling fan is re-
quired 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 necessa-
ry.
Replace any fan that is damaged.
9) FAN BELT TENSIONER
(1) With the engine stopped, check the tensioner
arm, pulley, and stops for cracks. If any cracks
are found, the tensioner must be replaced.
(2) With the belt installed, verify that neither ten-
sioner arm stop is in contact with the spring
case stop.
After replacing the belt, if the tensioner arm
stops are still in contact with the spring case
stop, replace the tensioner.
(3) With the belt removed, verify that the tensioner
arm stop is in contact with the spring case stop.
If these two are not touching, the tensioner
must be replaced.
After replacing the belt, if the tensioner
arm stop is still in contact with the
spring case stop, the tensioner MUST
be replace.
