I have a "leaning in" 'bent' Alternator, you can see its out of line with flywheel.. this car had a A/c in it, but was ripped out, my question is , what hardware is used and what am I missing to stiffen this up? you can see from pic Im using a 3 hole triangle plate, with top hole for A/c un used. and a long shank and shalf through the front of alternator, with nothing holding the front causeing the lean, is this how the other Challengers are, everyone's lean?

The triangle bracket is in the wrong place. It is supposed to attach to the two water pump bolts and the unused hole in your pic attached at the front of the alternator.
Here is a pic the (not correct it is a mock up of a bracket for a GM alternator) but gives an idea of how the bracket should be attached to the water pump. On your car it will line up with one of the holes at the top of the head, not the lower hole shown here.

Hmm then where does the slide bracket to adjust belt at the bottom of the alternator go.. yours don't show

TIP: Cover those unsightly spacer tubes with shrink-tubing. They'll look nice for a long time.

That triangular bracket needs to be on the FRONT of the alternator. The hole that is currently open is for the long bolt that goes through the alternator. the other two holes mount on the water pump bolts (one of them is doubled with the adjustment bracket).

Just my

Great response guys thanks for the help, extra thanks to you gtx6970, I see now that I got it all messed up, and am missing the smaller spacer, to fix this.Just got to find one or at least how long they are.

Thanks again all

You need to think big...

I actually have a 3 holes on the right and one on the left, with my bracket, and no where does it hook up with the front of it to the water pump, holes don't match up, I ordered the 3 hole bracket,Hopeing it fits, wish I could still see the top bracket hooked up better and close up, where does the small spacer go, and does that looong bolt go in the single hole of triangle bracket then through the alternator then into the head or just ends with a nut, also the bottom bracket I have is shaped like a Y 2 on the engine and one slide (tight) adjuster to the alternator, not a single peice
Any more help, Im confused

Just so it's clear, I made a picture

Move the bracket to the front, and line up the holes as colored:

ok looking at the pic some more..


i think you have the a/c pulleys

you have the 1 alt belt straight down to the crank and the ps and wp run on a belt

you just need the front alt-a/c bracket to support the alt pivot bolt

that will line the belt up straight

look at the belt you have on the front groove of alt to the crank...see the rib on the neck of the wp that wont let you run another belt in the rear groove from alt to crank

thats the piece you want to remove and file flat and run 2 belts on the alt

other option is get non a/c pullys and alt brackets(like in all the pics posted) with correct belts and a single groove alt pully

the other thing to remember with the pully ratio is the a/c wp use the smaller pully and 6 vane wp

the non a/c pulleys use a larger pully and 8 vane pumps

not good to mix match the pully ratio and wp vane count either on high rpm engines,it can cavitate at the wp vanes.

Here is a decent picture showing how it should be. I did a simple image search on Google.

the 3 hole y lower alt bracket is a a/c lower alt bracket

it will be used with the rest of the a/c brackets

the othe flat swing arm is for non a/c set up

cant strees it enuff..dont mix match the stock a/c or non a/c brackets and pullys

you just need that 1 a/c front bracket and 1 more belt for the alt and crank to be set up good to go

every one is correct showing you the non a/c brackets/pullys and the way it mounts...but you have 2 of the 3 a/c brackets and they are not the same and wont fit any other way.

Another:

BB and SB do not mix and are different mounting brackets

Sorry about that big picture, but that really shows how it should be.

I agree with scratchin... You can't mix and match AC and non AC parts. I had major issues like that years ago with one of my 71 Dusters that had an aftermarket AC setup on it at one time. Finally, I just went to a junkyard and got all non AC brackets and pullies.

So i can't use the lower A/C Y shaped lower bracket with the Non-A/C 3 hole triangle top bracket? and at the end of the long bolt on the top, does it go all the way through and then into the head.. that big pic is nice but it doesn't show.

Im so confused and its a big mess now of mis-matched parts, I have 2 pullies on my alternator but only use 1 since my A/C was ripped out

thanks for the color diagram, but i already tried to flip it, like you showed and it didn't line up at all, and to add the big pic there shows 3 holes on the right of the triangle bracket, I only have 2 in my water pump

ok,yes you may use the lower Y slide bracket with the non a/c alt 3 hole bracket it would share the same lower side bolt on the water pump

on non a/c alt bracket the pivot bolt goes into the hole in the head,bracket for front of alt on pivot bolt with spaces in place,2 long side wp bolts holding bracket

now the alt is hung..

swing arm goes on lowr side wp bolt to swing up to alt bolt

the bracket you need goes across the bolts on the top of wp

this is a/c brackets,the alt pivot bolt does not goe in the head but into the offset hole of bracket with pivot bolt and nut...like you have now

all you need is a a/c comp front bracket to support the front of the alt and push it back in line

you have a belt straight to the crank bypassing the a/c comp now

it may need to be a little longer when you get the front bracket

dont look at the BB pic posted and when looking at the SB pics they have non a/c brackets and pullys so you cant get that with what you have on there now

you could take some flat bar and drill holes in each end then support the front of alt from a water pump bolt,line it up with the belt off and get it supported first then install a correct length belt

if you look at the sb with a/c,you see the 2 belts over the top of the a/c comp going to the alt,you need that front bracket on the a/c comp

then run the belts down to the crank like you have it now

clean up the web/rib on the wp neck and you will get both belts like the a/c used on the alt

if you want a true later style non a/c set up you need a non a/c 1 groove wp pully and a 2 groove crank pully for ps

they have a single groove crank pully for non a/c manual steer also when your looking so remeber 2 groove for ps

also looking at the sb pics some of the non a/c brackets have 3 bolts in the wp and the alt pivot bolt into the head...those are for an early style cast iorn wp.. may or may not work on alum wp

but the exploded pic of the brackets are what you want with 2 correct pullys to match for non a/c and ps


now you fused?

look at the pic of the 73 cuda

you want that front bracket holding the a/c comp

see how it goes behind the a/c pully and over to the alt pivot bolt

thats what you need and your done

just the wp mod to run the 2 short belts just like you have on there with the 1 belt

On the engine stand

Out of all the eng pics I have taken this is the best showing at least a little of the alt mounting. Ron

Heres a shot of a 73 cuda 340 no AC car alternator shot.

but he has the a/c brackets and pulleys and is bypassing the a/c comp doing it the shadetree way on the cheap.

going by his pic posted anyways,he is just missing the front a/c bracket to hold the alt.

he will need the 2 non a/c pulleys and alt bracket to chang over to non a/c and LOOK correct.
