When to replace the timing belt and tensioner?
Replace if any movement is detected. With the timing belt removed, check both the idler and tensioner pulleys for roughness when rotating the bearing. The idler & tensioner should spin freely and smoothly. Replace bearing (s) if roughness is determined.
What does the pulley on a timing belt do?
Everything is mounted on the base in the spring is what is used to keep things pulled tightly in place. The pulley allows the belts to move as necessary in the system and the tensioner arm is a counterbalance to the spring allowing the timing belts to move and adjust as necessary.
What’s the difference between Pulley and tensioner arm?
The pulley allows the belts to move as necessary in the system and the tensioner arm is a counterbalance to the spring allowing the timing belts to move and adjust as necessary. Without the tensioner arm you wouldn’t be able to pull the bell tree to replace it with a new one.
What causes the idler pulley on a tensioner to fail?
The idler pulley accounts for about half of all tensioner failures. Misalignment of the timing belt can cause premature failure of the idler pulley or the pulley on the tensioner, as well as the belt.

What causes the timing belt and idler to fail?
Misalignment of the timing belt can cause premature failure of the idler pulley or the pulley on the tensioner, as well as the belt. Generally, this indicates that the tensioner or idler is not attached to the mounting location on the engine correctly or the bearings for the tensioner, idler or both, have worn and have excess “play”.
What causes a belt tensioner pulley to squeak?
Tensioner pulley wear will cause your pulley to squeak. A worn out pulley bearing or a worn spring in the tension pulley can also cause squeaking or a chirp. I show you how to use water to identify what type of squeak problem you have and then how to find the problem.
