First, all aspects of the altenator's front housing part are completely cleaned, closely inspected, and finally retapped under close adherence to Subaru's standards of excellence. The drain hole is located, allowing any moisture to escape, so that proper re-installation can occur. Only genuine Subaru parts are used in the remanufacturing process.
Factory-trained technicians then inspect the armature closely to ensure that all components are working properly, then test it for continuity performance.
The pulley is closely inspected for any damage and then thoroughly replaced or refinished.
Bearings are different in that they must be totally replaced with new, genuine Subaru parts. This ensures the overall performance of the remanufactured alternator.
To inspect the stator, techs administer a 600 volt performance test to check its functionality. If a component is discovered to be performing subpar, it is swifty replaced with a component that meets Subaru's strict standards.
Terminals and insulators are always completely replaced with new, genuine Subaru parts, as a certain level of conductivity is required to avoid overall unit failure.
The commutator is a component within your Subaru that works to avoid brush bounce to maintain consistent voltage output. It is reconfigured to the average 8 micron runout with a max 20 micron, and must also meet genuine Subaru original equipment manufacturer (OEM) specifications.
The voltage regulator within your Subaru's alternator is also totally changed out with a new, OEM Subaru part, to ensure continued safety and reliability.

Technicians will refinish rear housing as needed for the maintenance of insulation and corrosion protection.
Brushes, brush holders, and springs are always totally replaced with new, genuine Subaru parts, as these items can wear down quite fast due to brush bounce.
