Subaru Remanufactured Alternators
Since alternators are typically subjected to severe temperature extremes, dust and stress, restoring one to like-new condition requires total disassembly and complete cleaning. All major components are thoroughly tested for proper operation.
Any parts found to be out of OEM specification are replaced with new. Many external parts are replaced to provide maximum resistance to corrosion. After complete reassembly, the remanufactured alternator must pass thorough output power and "load" tests.
 Front Housing
Cleaned, inspected and retapped to Subaru specifications; replaced with new Genuine Subaru component as needed to return dimensional part to OEM specifications. (Properly installed housings with the drain hole correctly located allow moisture drainage.)
|
 Armature
Continuity performance tested; replaced with new Genuine Subaru component as needed to meet OEM Subaru specifications.
|
 Pulley
Checked for damage and refinished or replaced as required
