As I mentioned above ... I did a lousy job of sharing with this community how I did it, so please excuse the length of this reply and I'll give you my steps.
1. Remove the adjustment bracket and the mounting bracket when removing the bad alternator.
2. Take the new alternator and the mounting bracket to Tacoma Screw and find a single long bolt.
3. Take the alternator, mounting bracket, and new bolt to Home Depot and get a "spacer" pipe of the correct diameter cut to darn near the exact dimension of length. (Darn near ... highly technical term.
)
4. Pick up a couple neoprene washers while I'm at HD to fit between the spacer on the bolt. (I had an irrational premonition of an annoying high-frequency rattle ... though why I thought I'd be able to hear it is beyond me!!!)
5. Take the adjusting bracket and bolt supplied with the alternator to a local machine shop to mill out the bracket. I emphasized - and paid for! - the importance of this being "true", since I could also imagine doing it myself and screwin' the pooch!!! Better to let the professionals do it ... ;-}
Once back at HQ, the biggest issue I ran into was the need to remove a small coolant overflow pipe just so that I could get a decent angle on wrenching. Besides that, the install was painless.
I've had no issues with mine .. 'cept for my choice of belts.
From what I've read, when using twin belts like these, it's important that they are "matched". I didn't know that when I purchased these, and as they began to stretch into their 'normal' shape, the front one rolled.
I mentioned the "matched" concept to my guy at Napa (an old timer who I have a lot of confidence in), and he'd never heard that phraseology nor could he find anything in ***his*** computer. When I explained the conundrum, his advice was to try and get the same batch number when you select the belts, with the presumption that if they're created from the same material on the same machines and hopefully at the same time ... the tolerances would be very similar.
Here's a bunch of pictures. Feel free to contact me if you have any questions.
Good luck ...
