I have an 1989 GMC V1500 suburban, without boring anyone with the details, is there another way to mount the alternator and power steering pump. I have the serpentine belt setup and a factory installed 350 with tbi, is there another factory way to mount the gear there????

Not using the serp brackets there isn't. You could swap in some older v-belt style stuff and move some things around but you may also need to change the P/S pump as there were many different styles of brackets and mounting locations for the bracket to pump.

Why do you want to move things around?
 
I'm attempting to mount the air compressor next to the alternator. I was looking for an easier way to bolt the a-6 to the ds head, but it looks like I'm back to the original plan of master fabbin' a new power steering, alternator, air compressor bracket.

By air compressor are we talking OBA? If so then Kibly enterprises sells a bracket kit to mount a York on the drivers side outboard of the alternator. I'm running that kit on my rig.
 
untill you see the price of kilby stuff these days.

i will try my darndest to not buy his stuff. after he jumped the mount for 89-95 serp belt style york to a/c position from 45 bucks to 150 and no middle ground in the jump. just wam there it was.

and its just a bent 90* and 3 tubes welded to it. :dunno:

I never said the Kilby price was sane but it is an option. There are many pieces to the kit I have though. When I bought my kit it also came with the required serp belt and I don't think the kit comes with the belt anymore either.
 
If I run oba with a york then I don't have the room for the weldenator or the hydraulic pump. That's the thinking at least. I'm pretty sure I could swap out transfer cases and run the hydraullics by pto, but then I'm still stuck trying to fit the weldenator in there some where. Btw the air conditioning is staying right where it is.
I might be able to fit the weldenator in thr factory smog pump hole. Just thought of that, I'll explore it after I get done drilling holes for the passenger tube slider I'm actually taking a break, just finished the rear holes, getting ready to lay out and drill the front)

Thanks for the input and cconversations, keep on rollin'

My factory AC is in it's stock location and i'm going to build a weldernator and put it in the AIR pump location.
 
Have you figured out which case you're running with?

I'm thinking I can master fab out a 12 si without spending to much money. The pic is of the **** I scavenged over the winter prepping for the weldenator

I haven't even played with it yet. I think I can fit a factory 89 alternator in the AIR pump location though with little to no modifications.
 
When I got done with the ps slider I popped the hood and took a 12si alternator and set it in the position. It looks like a few little brackets needed to be master fabbed, and that's really it. The bitch is going to be the wiring that has to be set in the back. To adjust, or replace the wires on the back the alternator or should I say the weldenator will have to be removed to work on the wiring. Not really a deal breaker, but it adds to the frustration level. I've got this one in the back of the brain housing group now! I'll get some pics so I have a better idea of what I need to come up with. How were you going to run the belts off of the factory serpentine or from a pulley added to the crankshaft? I'm going with the latter.

Well, I have a pulley that I saved from years ago that fits inside on a stock pulley and then protrudes past the outermost of the serp pulley so I could go that route but I might just use a factory belt that used an AIR pump and route the belt accordingly.
 
A-6 testing

Well got all of the gear fabbed out to test the a-6 in the whell well location. I took a remanufactured western snowplow motor and fabricated an 2" 1/2" v-belt pulley, the shaft onthe motor was .855" with a facked off keyway, so I figured I'd just make my own.The set up looks good and doesn't sound loud, but the problem is that as soon as begins to fill with air pressure, the motor won't spin, it just stops in place. Worst case I found out the direction of rotations for both the motor and the A-6 compressor. Might sitll have a use for the motor, before I give up I'll try and spin the weldenator because I don't have enough room under the hood for all three. I'll give the weldenator it's shot on the motor sometime this week.

If you just capped the output air supply then that would explain why the motor stops. You'll need an air tank and also a pressure switch to turn the AC clutch off when the pressure reaches the predertermined pressure (make sure you use a pressure switch with a relief valve to unload the pressure on the AC pump so it doesn't try starting under pressure.
 
It was a matter of a second after I put my finger over the outlet that the system stopped. That compressor takes alot more balls to spin then the motor can produce with that pulley on it, I know if I would double the size then I think it would spin it, but the speed would decrease by half, at least. Then it would only take years to build pressure, just a thought that I wanted to try. I have some other motors that I will try, but I don't think it will have any better effects.
 
Since I'm at a stopping point for the oba I decided to play with the weldenator. My first test I got 46.6 amps @ 250 rpm. The second was 51.3 amps, I hope to break 60 amps at 250 rpm that way I can weld at idle. I'll post pics when I get home
