You can replace only the regulator on it, and it works. ;)

Here is what needs to be done to R&R an alternator.

I assume you have the tools and know how to do these things.

You may or may not need to do all of the steps listed depending on the condition of your unit.

1. Disassemble the unit and replace the bearings.
2. machine the slip rings if needed.
3. Check / replace the diode assembly.
4. Replace the regulator and brush assembly.
5. Load test the alternator.
