How long does a tensioner pulley last?
An idler pulley is a simple device used to keep tension on an accessory belt. The pulley will fail eventually because it will wear over time. Replacement intervals for idler pulleys range from 50,000 to 100,000 miles.
When should I replace my tensioner pulley?
The drive belt tensioner can wear down over time, just due to normal wear and tear. It’s a good idea to have it inspected each time you have your belt system looked at. The goal is to replace it before it actually breaks down, and causes your vehicle to run less than perfectly.
Is the tensioner pulley supposed to move?
It’s normal for it to move a little. That is to say it’ll rotate on it’s pivot. Secondly, should a belt tensioner wobble? A bad belt tensioner spring will often cause the tension arm to bounce up and down with the cycling of the motor.
What happens if the tensioner pulley fails?
When the tensioner or tensioner pulley fails, the loss of tension can cause the belt and pulleys to make high-pitched rattling or chirping noises. If the pulley bearing completely fails, it can also cause a squealing or even a grinding noise.
Should a tensioner pulley spin freely?
Checking the Tensioner Spin the pulley to see if it spins freely. If you hear grinding or the pulley doesn’t spin freely, replace the tensioner. When you replace the belt, it should take a lot of muscle power to move the tensioner. If you can move it easily, the spring tension is most likely not tight enough.
What causes a belt tensioner to bounce?
Excessive arm movement or bounce due to a worn damper: The damper moderates the action of the tensioner spring in much the same way that a shock absorber dampens a vehicle’s suspension. As the damper wears, the tensioner arm can bounce away from the belt, causing excessive belt slippage.
Is the belt tensioner supposed to shake?
Causes of Belt Tensioner Wobbling If your belt tensioner is chirping or makes other noises, it is often an indication that the part is old and needs to be replaced. If the belt tensioner is moving more than it should, there is a good chance it will require replacement.
