What causes a pulley to slip on a V belt?
There is a wide variety of reasons V-belts and pulleys slip. Some important reasons are: If belts become hard and glazed, and/or are operating in dusty environments, they can begin slipping in the V-grooves of conventional metal pulleys, abrading them in the process.
What causes a V-belt to slide backwards?
Belt slippage occurs whenever torque demand exceeds the available friction between a V-belt and one or more of the pulleys (sheaves). When this occurs, the belt begins to slide backwards a bit as it moves with the pulley.
What kind of particulates can cause belt slippage?
Particulates, whether they be mineral (dirt, silica, or quartz), agricultural (organic), or synthetic (hydraulic fluid, oil) can severely degrade belt/pulley friction. Particulate contamination behaves like both a lubricant and an abrasive.
What causes the belt to slip on a manual transmission car?
When this occurs, the belt begins to slide backwards a bit as it moves with the pulley. This action is similar in two ways to slightly slipping the clutch in a manual transmission car: It is a variable effect, ranging from under one percent to ten percent and more; and

Why is my serpentine belt slipping on the tensioner?
Remember that the belt riding forward on the tensioner pulley is the symptom and not the cause. The root cause was the Harmonic Balancer even though the Harmonic Balancer appeared fine. well done i know how hard it is to work them out.
