Refresh your Alternator! DIY inside!

Post by RoughDiamond »

Space saver for now, since I'm still getting the pictures together.

Since you've clicked this, you either are OCD about the quality of your car parts (like myself), or your alternator has died.

The stock alternator on our cars is mfg by Hitachi (Not Mitsubishi like the newer EJ22 and 25).

Here are the parts so far:

Pulley end bearing: SKF 63032RSJ, National 303CC, ORS 63032RSC3
Rear end bearing: SKF 62012RSJ, National 201CC, ORS 62012RSC3

Brush assembly still available from Subaru, ~$35 online.

If you need a new rotor assembly, one from an EJ25 MY00 or MY01 (maybe more, but these are confirmed) Outback alternator will work ($10 at a junkyard)

I haven't confirmed yet, but it looks like the diode and stator assemblies will also work, but the VR is different due to the different plug style. IIRC, early Hondas and Toyotas have VR that will work, but unconfirmed.

I haven't actually compared the VR assemblies, but in think you could run the 89-94 VR and the 00-01 guts. The 00-01 are Hitachi units and rated at 90A where the 89-94 are rated to 75.
