What are Alternator Bearings?

Alternator bearings are small, precision-engineered components that allow the alternator to rotate smoothly. Over time, these bearings can wear out and cause the alternator to malfunction.

Common Mistakes to Avoid

1. Using the wrong size bearings: Using the wrong size bearings can damage the alternator and cause it to fail prematurely.
2. Not cleaning the alternator before installing new bearings: If the alternator is not clean, dirt and debris can get into the bearings and cause them to fail.
3. Overtightening the bearings: Overtightening the bearings can damage them and cause them to fail prematurely.

Advanced Features

Some alternators have advanced features that can make changing the bearings more difficult. For example, some alternators have a built-in voltage regulator. If you are not experienced in working with electrical systems, you should consult a qualified mechanic before attempting to change the bearings on an alternator with advanced features.
