What is Back Pulley (Tension Ball), and how do you define it?

The tensioner pulley (also known as the tensioner balls or tensioner roller) is an essential part of the vehicle’s drive belt system. Timing belts (or V-belts) are used for transferring some of the engine’s power to other parts such as the alternator, charger, water pump, power steering pumps and air conditioning compressor. The correct tension is necessary for these belts in order to power different accessories. The tension pulley is here to help.

Tensioner pulleys are used to maintain constant tension on engine belts. It is usually equipped with a spring mechanism or an adjustable pivot. Spring types adjust the tension of your belt automatically so that you have the right tension every time. Because the tension of these pulleys can wear down over time, it is important to replace them regularly. A screw is used to adjust the pivot type. Both are used for maintaining a constant tension on engine belts in order to allow the use of various engine accessories.

Tensioner pulleys with serrated channels can be used for vehicles equipped with timing belts. The V-belt pulleys are flat.

 

What are the Signs of Tension Pulley Problem?

Failing tensioner pulleys can cause problems with other belt driven components. This can adversely affect vehicle performance as well as functionality. Sometimes, a malfunctioning or defective tensioner pulley will cause several symptoms. These are the most frequent symptoms of malfunction:

 

Squealing Belts or Balls

A noisy tensioner pulley or belt is the most common sign. When the engine is started, you will hear a clicking or squeaking sound coming from the belts and balls. If you hear a rubbing sound or squeaking noise, it could be due to the ball. Over time, this part can wear down. This can lead to a rubbing sound or ball that is beginning to wear.

 

Unusual Belt Wear

A faulty tensioner pulley can also cause unusual belt wear. You may see patterns along the length depending on which type of belt you have. A problem with the tensioner pulley can cause the belt’s wear to accelerate and even stop completely. Defective pulleys can cause the belt’s edges to fray or, in more severe cases, break.

 

Failure of all Belt-Driven Accessories

Failing tensioner pulleys can lead to all accessories that use the belt to fail. The accessory belt is used by many parts such as the alternator, water pump, power steering, and air conditioning compressor. The belt can fail if it is not properly tensioned or jammed. You may also experience symptoms like engine overheating or battery discharge while driving and an inoperable air conditioner system. The belt and pulley should be replaced.
