Here we will cover everything from Harley automatic primary chain tensioner problems that arise in your car. We will also discuss warranty information and tips for maintenance.
Solution Of Harley Automatic Primary Chain Tensioner Problems
Tensioner problems can be a major headache for Harley-Davidson owners and mechanics alike. The tensioner is responsible for adjusting the tension of the primary chain, which controls the oil flow to the engine’s various moving parts. If this component is not working properly, it may decrease engine performance or even something more serious, such as engine failure.
One of the main causes of a faulty tensioner on a Harley-Davidson motorcycle is worn-out seals. A seal can become damaged over time and lose its ability to maintain proper oil pressure. This leads to increased friction between the chain and sprockets, which results in decreased horsepower and efficiency.
Another common cause of a faulty tensioner on a Harley-Davidson motorcycle is incorrect maintenance. Inaccurate fluid levels can lead to a misaligned tensioner position, resulting in reduced oil flow to the engine. Scroll down to get Solutions on Harley automatic primary chain tensioner problems.
