Rebuilt Denso alternators - who's doing all that rebuilding?

[Seymore Butts]

It appears that new Denso and Bosch alternators are not on the market any more. There are lots of rebuilt units, but I'm wondering who rebuilt them? Is there such a thing as an authorized Denso or Bosch rebuilding depot, or are these rebuilt with cheap parts by some guy in the back room of whatever supplier sells rebuilt units?

Ever see those car crushers on TV - part of the recycling story ?

I wonder if the engine or parts like the alternator are pulled out of the car first ?

I know the teeth are strong on those industrial shredders but seems a few engines would clog them.

So when my oem unit "denso" went out I ordered a rebuilt denso unit straight from Toyota dealership (rebuilt is all they offered, no brand new). Toyota didn't require a core exchange so I then brought my old starter to one of those random starter rebuild places had them rebuild it so I can have it as a spare. I bring it with me to all my long trips out of state.

The random rebuild place charged me $80, showed me what part broke/ failed, and showed me the starter engaging/ working correctly before I left.

I worked at a steel recycling plant that had their own shredder which was primarily fed cars. Can't speak as to whether parts were pulled out before we got them but we unloaded them directly to the shredder. And no, an engine is nothing for these things. In fact, the shredder at our plant could go through them all day, it was the structural stuff (bridge girders, I-beams, ect) that gave it any trouble. Runs pretty smooth until a car comes in with a full tank of gas!! :snacker:

Atlanta Man - around here, car crushers pull many alternators out of junk cars and sell them in bulk through brokers who exist specifically to supply rebuilders. They actually get about $20 per unit, which makes it worth their while to pull out a lot of alternators.

My guess is they farm it out with a Service Level Agreement that specifies they type/quality components and QA/testing that they need to meet for the specified price.

Toyota prob specs several new components while the 'lifetime' warranty stuff that is cheaper uses less parts or lesser QA/testing process.

The problem is that anybody can rebuild an alternator and sell it is a "Rebuilt Denso Alternator". None of the on-line sources that I looked at claim that the alternator was rebuilt by Denso or under contract for Denso and to Denso specifications.

For all I know, it was rebuilt by some chain smoking drunk in the back with the crappiest Chicom parts they could find with a TV blaring on the workbench.

Denso does rebuild/reman. their alternators, whereas if anyone else does I don't know, but if you get a rebuilt Denso alternator it should have documentation with it which should point to who rebuilt it or at least if it was done by Denso, I just put a rebuilt Denso alternator on my wife's Rav4 last weekend that was bought at NAPA, it had documentation in the box that showed it was rebuilt by Denso, that documentation had the same wording and Denso's trademark name that is seen on the Denso website linked below, the same wording is on the info link for a Denso reman, from RockAuto as well.
