Drive Belt: Testing and Inspection
INSPECTING AND ADJUSTING:
Examples Of V-Belt Failure
-
Proper V-belt maintenance, by correcting loose or overtight belts, can extend the life of the belt and the component it drives. Inspect belts with the
engine off, and twist the belt to see its sidewalls and bottom. Belt structural damage, glazed or shiny sidewalls caused by a loose belt, or separation
caused by oil contamination are all reasons to replace a belt.
-
V-belt squealing is normally caused by incorrect belt tension (too loose) or by contamination between the belt and pulley. Extremely loud
squealing may only be corrected by replacing the belt. Belt dressings should not be used to correct the problem. Many dressings contain oil-based
compounds which can soften the rubber and reduce belt life.
-
Check V-belt tension by checking the amount of deflection when the belt is pressed midway between two pulleys.
