      • Convenient alternative to sourcing individual rebuild components separately

      • Cross-referenced to OEM and aftermarket alternator part numbers for easier identification


      What Does an Alternator Rebuild Kit Do?

      An alternator rebuild kit provides a selection of replacement components commonly needed to service and rebuild a worn or failed alternator. Depending on the specific kit, components may include bearings, brushes, brush holders, slip rings, rectifiers, voltage regulators, and other service parts required for the applicable alternator design.

      Rebuilding an alternator allows worn internal components to be replaced while retaining serviceable major components such as the rotor, stator, housing, and pulley when they remain within specification. A properly rebuilt alternator can help restore reliable charging output, smooth mechanical operation, and dependable electrical system performance.

      Always review the Kit Contents for the specific rebuild kit before ordering, as included components vary by alternator application.


      Common Signs an Alternator May Need Rebuilding

      Consider rebuilding or servicing the alternator if you notice:

      • Battery warning light illuminated

      • Low or inconsistent charging voltage

      • Battery not charging properly

      • Intermittent charging system operation

      • Grinding, whining, or bearing noise

      • Worn brushes or slip rings

      • Failed voltage regulator or rectifier

      • Excessive bearing play or roughness

      • Internal component wear discovered during alternator inspection or testing


      Installation Recommendations

      Installation should be performed by a qualified technician or experienced alternator rebuilder. Before rebuilding the alternator, completely disassemble and inspect the unit for worn, damaged, overheated, or contaminated components.

      Inspect the rotor, stator, slip rings, bearings, rectifier, voltage regulator, brushes, brush holder, pulley, housing, terminals, insulators, wiring, and fasteners as applicable to the alternator design.

      Always verify the Lester number, OEM alternator number, alternator series, specifications, and product photos before ordering. After reassembly, bench-test the alternator to verify proper charging output and overall operation before returning it to service.


      While You're Rebuilding

      Depending on the contents of your rebuild kit and the condition of the alternator, inspect other components that may require replacement:

      Important: Rebuild kit contents vary by application. This kit includes only the components specifically listed in the product description. Components listed above are inspection recommendations and are not necessarily included with the rebuild kit.
