Alignment issue after 351w alternator bracket

[bushcal]

I’m having trouble as to why my alternator doesn’t line up with the crank and fan pulley after installing the 351 alternator brackets with the 302 water pump.

I have the correct spacer behind the alternator bracket and the bracket for lowering the alternator position. But the alternator is about 3/4” too far towards engine

That’s strange. I thought you were going to say it’s three-quarter inch too far out.
Any chance you could get a picture to show us?

And by “correct“ spacer, are you using the original, or something else?

 

[DirtDonk]

Oh, and did anything else change? New alternator, or water pump, or anything else by any chance?

Have the WP pulley part E7SE -A528 BA
and bought these from bronco graveyard
10742B Alternator Bracket Set, 289-302-351W Black 289-302-351W
10743 351W Alternator Adapter Bracket

It use to have a huge upper alternator bracket that wouldn't allow the hood to close

I changed the water pump to a 302 one since that what the above brackets fit with. Seems a little bit (maybe 1/4) shy of where the original on was. But i think i can shim it if i have to.

Im new to this bronco, Love working on cars...when i know what the heck to do....LOL

Ok, time to verify that you indeed have a 351 first of all. But also you'll have to likely start at zero and work your way up with what you want.
Nothing you buy for a Bronco will be correct for your belt drive setup. Your pulley indicates an '87 or later part (E7 means '87 in Ford engineering number-speak) and the rest of your stuff is obviously serpentine accessory drive stuff.
So you now have a mix of parts that were never made to work with each other.
You can't just start putting '68 Bronco parts at it, or just "302" parts at it and make anything work until you use ALL parts from the same year and model engine.

Usually it's not the hood that has trouble with serpentine stuff. It's usually the radiator clearance to the fan. Got pics of your motor mounts?
And while we're adding pics (thanks for that one by the way, speaks 1,000 words), might as well show the body mounts as well. If you have crushed original rubber mounts, maybe the hood clearance was a result of that instead.

But there's no doubt that some ford serpentine drive setups don't play nice with Bronco engine compartment sizing.
The Ford Explorer V8 stuff is the best, but you need it all from the timing cover forward, and can ONLY use Explorer accessories for the most part.

I can't enlarge your pic quickly, but it looks as if you have an early 1G alternator with the serpentine pulley setup on it. Might be indicative of it being from a truck, and given it's a 351 supposedly, follows suit because not many 351's were found in cars during this era.
Or it might be some other setup, but the BAT terminal on the side of the case is what's so interesting. It's not a 2G or 3G alternator, so it's either a 1G or a swap from another brand.

Looks like you might have to dig back in and determine just what parts are what, and from what. So you can find parts that play nice not only with the Bronco, but with each other foremost!

dude...thanks so much for the information. Truly is amazing how cool this community is and I haven't even been here but a few days.
Motor definitely is a 351 out of a full size car........for the little research I did

Motor casting numbers are

E3AE-6015-BA2
(look's like (4h16v under it)

Transmission Casting
C8AR 7006- C
Little tag has RAT AH 020206

I'm afraid your above response is correct and i will have to start from scratch and see what parts I can make work. Just already bought multiple water pumps..HAHA
That's what i get for thinking it was going to be easy....

ill send a picture of the motor mounts and body mounts...and this monstrosity alternator bracket when i get home...hah

I think I know which bracket you’re talking about. About that vintage it was pretty large.
Especially if it was from a truck.
Just because the engineering number says it’s from the car line, doesn’t mean that it wasn’t originally used in a truck. They didn’t make many specifically truck engines over the years.
Most Bronco engines spec out as “Comet/Falcon” engines.
Even though Ford installed them in pickup trucks and Broncos, I believe the story about these types of things is that the automotive engineers group was who designed or implemented a particular engine design.

James Roney has a good explanation about some of how this works in another discussion thread here today.

If you decide to replace the front dress sanndmann3 sells complete explorer serpentine kits for a good price in the classifieds

Great advice! And even though from then on out you can't run a mechanical fuel pump, or use generic parts for water pumps and alternators and power steering pumps, every component that works in the Explorer system is top notch to begin with.
Not only do you get more clearance (3/4" more than factory is it?), and a more efficient coolant flow, and a mega-strong cooling fan, but you never again have to remove everything to get at a water pump!
The pump can be removed pretty much by itself once you get the fan out of the way.

Never heard of anyone ever having cooling problems with their Broncos again, after having installed the '97-'01 Ford Explorer front drive setup.
