These are the part numbers for the components that usually fail in SR alternators. The components can easily be replaced.

Voltage Regulator: IM284

Diodes: IMR8576

Rear bearing: 10-800-4W

You have no idea how many people you would be helping you pulled this off.

Well I ended up pulling it off...

All the parts listed above fit perfectly in a S13 SR20DET alternator with the B post being in the back of the alternator and not out the side.

The downside, the B post is now 5mm and should be a wider post. There may be another rectifier out there that has a wider post, you just need to hunt down the right part number. Then again, you might not even need the rectifier, I just replaced mine for the hell of it since I had it apart. Most of the time it's just the regulator that is busted so you might just replace that at a cost of 20 bucks and some time.

Hope this helps some out

Are you still bleeding from it?

Local place I use does any alternator I bring them for $85, that includes sandblasting and painting the case too. Even a heavy duty unit from a truck doesn't cost more than $125 or so. Your place ass raped you like a school girl.

Has anyone else done this?

TheRealSy90 · 09-01-2011, 11:29 AM

Figured I might as well post in here. Went to the local rebuilder that everyone recommended. He told me these parts are no longer available and could only order me a whole new alternator for $130.

This held true in 07 and it still holds true today.
