According to the AIM L35 section, the bracket goes behind alt. Is that correct. If so, i have the wrong bracket.
Thanks Joe

I believe that is correct, but my alternator mounted behind the bracket just fine. Maybe it's the difference between an externally regulated alternator (like OE) vs an internally regulated one (mine is a CS130).

I have a reconditioned Delco alternator (correct dimensions as OE) with an external regulator, and from memory, I tried to mount the top bracket as per L35-A4 and it wouldn't fit well at all.
It is a repro top bracket that I have, so maybe it's not accurate. (That wouldn't surprise me in the least..)
It mounted in front with no problem.

Also. I have loads of "file" engine bay pics and not one is mounted behind like the AIM suggests.

From the rear, bolt, washer, bracket, alt. Bracket is on the rear.

I have an original upper alternator bracket, and I mounted the alternator behind the bracket. I did mate a deep groove alt pulley with all other pulleys being standard. That created the need to move the alternator aft, but no way did I move it aft as much as the thickness of the alternator ear plus the thickness of the bracket (approx 1/2"). More like 3/16" +/-

From the rear, bolt, washer, bracket, alt. Bracket is on the rear.

Got a pic?

See if this helps.

That pic is how mine is, but the AIM shows it differently. It shows the bolt as pointing forward and going through the slot in the bracket from the rear. The bolt would extend through the bracket and then thread into the alternator. A flat washer and lock washer are between the head of the bolt and the bracket.

It appears that if done according to the AIM, it would be very awkward to adjust.

I don't have my AIM handy,..can somebody scan and post the page in question?

I've seen a hundred BB 69's and have never seen the alternator mounting 'ear' in front the upper bracket. I also looked at numerous rather stock looking 69 BB Camaros currently for sale on ebay and other sites; none of the engine photos show the config that apparently the AIM describes. Have we been doing it wrong all this time?

I don't have a car in front of me but wouldn't that take the pulley out of alignment? I can't find any photos of original or top shelf restos that have it mounted in front.

Anybody have the AIM handy and a scanner?

I can't believe you guys don't have your own copy. :sad:
I bet you all have a bible that you hardly read.. Well, this is a bible for something much more important.. Your Camaro! :p

Also, I was asking Everett in hope that he could supply a pic of the bracket at the rear as per AIM. ..on a 69.
I'd love to see one, as like I said, I have loads of resto pics of some rare and high-dollar 69s and not even one has it mounted that way..

What a PITA it would be to make any adjustments if the bracket was a rear mount.

Found my AIM. Wow,..guess 99% of the BB cars have it wrong. L-78 or L-89 had a different alternator pulley,..but I guess the alternator mounting is the same as L-34 & L-35. Didn't see L-78 or L-89 mentioned in the AIM regarding this.

Also, I was asking Everett in hope that he could supply a pic of the bracket at the rear as per AIM. ..on a 69...I apologize on two counts : 1) I misread, I thought I read a '68 SBC; 2)I don't have my AIM here with me in Lima, Peru for the company I work, nor a scanner.

So we still don't have a definate answer if the AIM is correct or not. Anybody with a BB survivor, that can shed some light.

The manual is simply wrong !!!! I've seen and owned a few original BB cars and have NEVER seen an alternator mounted that way. It just looks plain wrong. I will gladly eat my words if anyone can prove ANY cars have come that way from the factory. I say NO WAY. The lower bracket would be different also as would all the pully's. NO WAY..................


JMO of course............

The Assembly Manual illustration is incorrect - the bolt installs from the front, through the bracket, into the alternator on BB's just like it does on small-blocks. :thumbsup:

JohnZ,..it's great to have you around.

I think 67s & 68s had the bracket behind..

I think 67s & 68s had the bracket behind..



I'll take that bet. A good friend still has the 68 RS/SS 396 he bought brand new in 3/68. Engines never been out and his alternator is mounted BEHIND the bracket. I cant believe this thread is still going........ THE MANUAL IS JUST PLAIN WRONG. Can anyone produce an actual picture other than a drawing :confused:

67 and 68 mounted the alternator on the other side of the engine. Completely different config.

in 67 The Alt is in front of the bracket.
69 it is mounted behind - not positive about 68 but would assume same as 67?

..69 it is mounted behind...

Unless you can provide photographic proof.. No it isn't! ;)

69 Is behind - I have removed 100's of these in the yards - this bracket was ALWAYS used with the Alt behind.

The AIM's have lots of mistakes in them - can't use those as absolute.
Some pages are old pictures from years before - some are simply pictures from other models - some are just guess' at the time.

Ahh, then we agree.
"Behind" has been refering to the bracket.

In front.:thumbsup:
