Overrunning AlternatorPulley F-551406

Short Description:

Since all pulley types are not interchangeable,   Therefore, it is important to use only the type of pulley originally equipped with the vehicle. Therefore, if the vehicle requires solid pulleys, OWC or oad, pulleys of the same category must be installed. Like any other component, overrun alternator pulleys will not last forever (technicians will replace more and more pulleys). Worn pulleys can cause vibration in the belt drive system and usually cause damage to the tensioner.

Dynamic test with engine running

1.open the hood

2.start the engine and let it idle

3.wear goggles to observe the belt drive

4.run the engine in different speed ranges and perform a visual inspection

5.shut down the engine and observe the alternator pulley for overspeed

Defective flywheels can be identified by the fact that the unit driver does not really operate and the resulting noise. An alternator with a complete flywheel shall decelerate and stop when the engine is switched off.

two

Static test with engine off

1.shut down the engine

2.remove the ignition key

3.remove the V-belt

4.remove the cap from the flywheel

5.application of assembly tools (a)

6.grasp and hold the outer ring of the pulley with one hand

7.with the other hand. turn the assembly tool in both directions

If the flywheel works properly. the shaft will rotate freely in one direction and lock in the other. Depending on the manufacturer. the resistance in the locking direction may increase.

If the above results are not achieved. the alternator freewheel clutch must be replaced
