PART INFORMATION

Rectifiers
•    Rectifier failure is one of the primary causes of alternator failures, most often caused by diode malfunction.
•    ACDelco rectifiers are 100 % electronically tested and replaced when needed.

Bearings
•    Bearings are always replaced with new
•    Bearings are critical to alternator durability due to extreme lateral loads applied by the drive belt, in addition to excessive heat and vibration.
•    ACDelco alternators use only quality bearings with high temperature lubrication and double-lipped rubber seals.
 
Rotors and Stators
•    The heart of the alternator and its current-generating components, rotors and stators maybe subjected to excessive heat, which can deteriorate insulation and cause shorts.
•    ACDelco rotors and stators are electronically tested for proper performance, then sealed with a flexible secondary insulating coating.
 
Slip Rings
•    Slip rings must be in constant contact with the brushes, or uneven wear leading to failure can occur.
•    ACDelco slip rings are precision polished to help maximize electrical contact and consistent output.

Brushes
•    Brushes are always replaced with new.
•    Worn brushes interrupt electrical contact, shortening the life of alternators.
•    ACDelco brushes are 100% new and durability tested for performance and reliability.
