Why is my belt pulley making a noise?

Spin the tensioner pulley by hand and listen to it. If the bearing is good, the pulley will spin freely, straight and true, without any noise. If that’s not the case, you have a bad bearing and must replace the tensioner. Unfortunately, the end result of any belt tensioner noise is usually tensioner replacement.

What’s the best way to remove a tensioner pulley?

Rotate the tensioner counterclockwise just far enough to slip the serpentine belt off the pulley closest to the belt (or pulley easiest for you to reach, depending on what kind of vehicle you’re working on).

How do you attach a serpentine belt to a pulley?

Connect the serpentine belt tool to the tensioner. Rotate the tensioner counterclockwise just far enough to slip the serpentine belt off the pulley closest to the belt (or pulley easiest for you to reach, depending on what kind of vehicle you’re working on).

What kind of pulley does a car use?

Most modern vehicles use a serpentine belt to run the engine accessories such as the power steering, air conditioning and alternator. The belt routes around the pulleys in a serpent-like manner, hence the name.

How to determine the face length of a conveyor pulley?

STEP #1: Determine the Face Length of the Conveyor Pulley. The face length of a conveyor pulley is a derivative of the conveyor belt width. In bulk handling applications, an adequate pulley face length is one that is 2” or 3” greater overall or 1” to 1.5” greater on each end than the overall width of the conveyor belt.

Why is the pulley selection process so important?

It is because of this essential role that pulley selection becomes a critical process in keeping equipment up and running. If select ion is conducted in haste, a conveyor pulley may be inadequately sized and selected, leading to premature pulley failure and costly downtime.

How is the traction between a drive pulley and belt increased?

The amount of traction between a drive pulley and a belt can be increased by increasing the arc of contact between the two surfaces. The arc of contact, or belt wrap is the angular distance a pulley travels while in contact with the belt, and is measured in degrees.

What causes excessive deflection of a pulley shaft?

Excessive shaft deflection occurs when shaft diameter is improperly sized for the demands of an application. Although it may appear as a potential solution, selecting a shaft material with greater strength characteristics will have virtually no effect on its stiffness as it pertains to shaft deflection.

What makes a belt sound like a squeal?

The #1 cause of serpentine belt noise is a worn automatic serpentine belt tensioner. Most people blame the belt and replace it only to find the belt noise returns.

Why do I hear engine knock in my car?

This belt must be under the exact right amount of tension so that it turns smoothly and quietly. If the belt becomes stretched out, the tensioner isn’t working properly, or one of the pulleys becomes bent out of shape, you can hear rattling, clicking and slapping noises that might be mistaken for engine knock.

What can I do about noisy accessory belt?

Luckily, fixing a noisy accessory belt can be as simple as replacing the belt, adjusting the tension or replacing a bad tensioner or accessory pulley. We’d be thrilled to help you out with this or any service at the Capitol Toyota service department.

Where does the knocking come from in an engine?

Another possible source of engine knocking isn’t actually coming from the engine itself at all. It could be coming from the accessory belt. As the engine runs, it turns a belt that’s connected to various pulleys throughout the engine bay. This belt must be under the exact right amount of tension so that it turns smoothly and quietly.

Why does my GM car make a sharp noise when I start it?

GM recommends inspecting the accessory drive belt area, power steering pulley to ensure the noise isn’t due to a fault in the serpentine belt or automatic belt tensioner system. If the noise is very sharp and present in short 2-5 second spurts, GM says the problem is with the cam actuators not parking properly.

Why does my car AC make a rattling noise when I turn it on?

What does the pulley on a belt tensioner do?

The pulley is what allows the movement of the drive belt. The spring keeps the drive belt in its correct tension. The tensioner arm is a mechanism that allows for the adjustment or the removal of the drive belt. It delivers enough slack on the drive belt for easier adjustments. The base is what holds all the different parts together.

Why does my belt tensioner make a squealing sound?

This is especially the case when starting the engine first thing in the morning. Since the tensioner is not able to maintain the correct tension on the belts, it produces a squealing or squeaking sound. This is most evident on the drive belts.

Why does my belt tensioner make a grinding noise?

If the noise you hear is similar to a grinding sound, then it is possible that the tensioner bearings or the tensioner pulley is the problem. These parts tend to wear out. This is what causes the grinding noise since the metal parts will be rubbing against each other. This is another symptom of a failing belt tensioner.
