Understanding Belt Friction And Tension
Misalignment and bearing wear can cause the belt to track off-center.
Tech Tip: Replace A Failed Water Pump And Timing Belt At Once
Here are three main reasons why you should have a conversation with your customer to replace multiple parts simultaneously.
Installing Subaru Stretch Belts
When a stretch belt exceeds wear specifications, it’s no longer able to grip the pulleys and will start slipping.
Dayco Tech Tip: Long-Lasting Vehicle Belts
Belts continue to be one of the most frequently replaced wear items on vehicles today. The typical replacement interval for serpentine belts and flat belts today is around 90,000 miles – which for many vehicles means only once every seven to nine years!
Attention To Tension: Why Start-Stop Engines Still Require Belt Diagnosis
As many start-stop vehicles are aging out of warranty, you are likely to be encountering them in your service bays.
VIDEO: What Is A Torsional Vibration In The Belt Drive And Pulley System?
Andrew Markel covers how the movement of the pistons create torsional vibrations in the belt drive system. These small changes in the speed of the crankshaft can cause vibration in the alternator and belt drive system. If the vibration goes unchecked, it could lead to belt wear and component failure.

VIDEO: Is Belt Tension Going Up Or Down?
With new fuel efficiency mandates, automakers are looking for every possible way to reduce drag on the crankshaft. Many automakers are reducing drive belt tension to not only improve fuel economy, but to extend the life of the belt. Andrew Markel explains how they are able to reduce tension while controlling vibration. Sponsored by Litens.
VIDEO: It Is Not Just The Belt That Wears Out
At 100,000 miles it is not just the belt that is worn, it’s the entire drive belt system. Failing to inspect and service the tensioner, pulleys and all the components the belt touches can cause premature failure of the new belt. Sponsored by Litens.
Engineering Better Belt Systems
When a piston accelerates downward after the ignition of the fuel and air, the crankshaft speeds up and then slows down as it reaches the bottom of the stroke.
Advanced Belt Noise Diagnostics
One of the noisiest components under the hood of a vehicle can be the belt and the drive components. Noise is not the fault of the belt, but the result of how the power comes from the crankshaft and the components attached to the belt.
