Next >About Alternator Bearings
The alternator bearing is important because it ensures that the rotor's shaft gets all the energy possible from the pulley. The transfer of energy is more sufficient when there is less friction.
Alternator bearing functionThe alternator bearing has the job of making the alternator turn properly to produce electricity. The electricity is then transferred to the battery, and the electrical power is used in systems such as air conditioning, lighting, and radio. Other systems are powered too but if the alternator bearing goes bad, the electricity won't be transferred to the battery.
Common problems with a bad alternator bearingAn alternator bearing can go bad and once it does you will have a dead battery and a broken alternator.
