Freightliner Cargo Maintenance Instruction - page 7

7.

Visually inspect the pulleys for excessive play or
wobble. Excessive play or wobble indicates a
failure of the pulley bearing. Check for belt
squealing or squeaking. Replace the bearings as
necessary.

NOTE: If it is difficult to distinguish the locations
of a supposed bearing noise, place a stetho-
scope on the component being checked, not the
pulley, to isolate the area from outside interfer-
ence.

8.

Inspect all pulleys for foreign objects, oil, or
grease in the grooves.

Belt Tension Inspection

NOTE: If engine drive belts require adjustment,
refer to Group 01 in the

Cargo Workshop

Manual.

On belts equipped with a spring tensioner, the belt
tension is automatically adjusted. Check that the ten-
sioner is holding tension on the belt by inserting the

end of a breaker bar in the 1/2 inch square hole on
the forward face of the tensioner, and rotating the
tensioner down, away from the belt. When the
breaker bar is slowly released, the tensioner should
return to its original position. If not, refer to Group 01
in the

Cargo Workshop Manual

for replacement in-

structions.
