Why are idler pulleys used in HTD systems?
These pulleys spin freely on built-in bearings to maintain tension for reduced wear and vibration. Keep high torque drive (HTD) timing belt systems running tightly with these idler pulleys. Made with built- in, free-spinning ball bearings, they’re installed on shafts or belt tensioners to remove slack from timing belts.
Why do idler pulleys spin on built in bearings?
These pulleys spin freely on built-in ball bearings to maintain tension for reduced wear and vibration. These pulleys spin freely on built-in bearings to maintain tension for reduced wear and vibration. Replace worn or damaged pulleys or create new belt conveyors.
Why does my serpentine belt make a squeaking noise when I start the car?
A squeaky belt can indicate several different issues. If the noise only occurs when turning, starting the engine, or accelerating, it probably is a worn or loose belt. A constant squeal may mean the tensioner system or a pulley is damaged. Diagnosing the sound is the first step in how to make a serpentine belt stop squealing.
What causes a high pitched squeal when you change a belt?
A new belt is recommended once the accessory drive has been realigned. “Squeal” is a high pitched noise, typically lasting several seconds in duration. This type of noise will typically increase in volume as the engine speed increases, and is caused by relative slip between the belt and pulleys.

What causes a belt to make a noise?
A belt installed incorrectly will make noise and if not remedied quickly, will need to be replaced On systems equipped with an automatic tensioner, the tensioner pulley should turn freely without binding, the tensioner arm should move smoothly through its entire range of motion and there should be adequate tension.
How can you tell if a car belt is a chirp or a squeal?
One method to determine if the noise is a chirp or squeal is to use a water squirt bottle and spray the rib side of the belt while the vehicle is running. If the noise gets louder, it’s a squeal. If the noise goes away, it’s a chirp.
What causes low tension on a car belt?
Low installation tension (manually tensioned drives), belt stretch, extreme belt wear, tensioner spring degradation or a belt that is too long Fluid contamination on the belt (oil, power steering fluid, antifreeze, belt dressing, brake cleaner, etc.)
