Clutch Pulley’s

 

Clutch Pulley’s are fitted to the later models of BMW alternators, they are prone to failure.

The failing of a clutch pulley can occur for a number of reasons, the two main reasons are:

            Failure of the cars automatic tensioner

            Belt flap (from the fan belt)

 

In addition to the above, a clutch pulley can fail due to incorrect fitting of the stretch belts.

How do I know if my clutch pulley has failed?

            The alternator could be excessively noisy in operation

            The shaft would be worn (although not easily visible)

           

 

Customers often query how the cars automatic tensioner can cause a clutch pulley to fail. We always advise them that clutch pulley and tensioner are serviceable items and should be changed at regular intervals. (This information is according to OE manufacturers specifications)
