Reviving a thread from the dead

I had a Denso alt go bad, so I sourced a junkyard unit out of another 4runner, it eventually died, too. Pulled it apart and found the brush holder was different than what OP posted
Attachment 402861
As expected, the brushes were gone, here is what new ones look like (spring loaded to contact the shaft)


Turns out there are potentially 2 different brush holders for these trucks/alternators, and without the VIN both will be "correct" for our trucks on parts.toyota.com

OP posted 27370-75060 which is the correct brush holder for an 80 amp Alternator

27370-35060 is for the 60 amp, and fits a 10+ vehicles


The tag on my bad alt was worn, so I bought both brush holders before cracking mine open, low and behold, I had the smaller 60 amp alternator.

The brush holder swap was as simple as removing 4 nuts and 2 screws.



Done and back on the road - I did not want to mess with the bearings lol
