Default Alternative Alternator????

Could an alternator like this be used on the ambulance?

The answer is a conditional "yes".. Any alternator can be used, if you can get it properly mounted so the belt will be in alignment with the drive pulleys to the alternator. If you can't get the alignment correct, the belts will have a very short life. I wouldn't change the alternator on your car to something that is different. If yours needs repairs, and the shop that it is at, is having difficulty finding parts, I would then look for a replacement. They were used for many years, and used alternators of the same type as you have are available with a little searching..

Is there a reason you dont want to stay with the altenator that your car came with?
Why don't you just send your altenator out to a rebuilder. trying to convert to a different altenator is going to be costly getting the mounts and wiring converted, not to mention that when your done, you will have hacked up you car while asking for complications for no reason.

My alternator is being rebuilt costing about $300. My thought is why deal with these old alternators when you can get a new one for under $100 providing it kicks out the same amount of amps handling my electrical load. I'm surpised I'm the only one to ever have the tension pully go bad and had to go out and find a bearing for it.

If something new is better, works the same, and is cheaper, then why not. As far as changing it from it's original form, that sounds good but that doesn't get you more value when it comes time to sell.

I was told today I could get my A/C system rebuilt back to original for about $2800 yet I can get a brand new total system for under $2500 with 134.a freon and in a system designed for it, or go with an under the dash system for less than a grand.

To me, as long as it cools it doesn't matter.

Just remember you get what you pay for and cheaper is not always better. I would go with a quality rebuild for $300 and never worry about it again, than buy a cheap $100 one and end up replacing it again in a couple years.
Just my opinion from experiance.

I got to side a little with Richard on this. after all this small standard size GM replacement alternator puts out more power then the boat anchor that weighs a ton one that is only a 100 amp that came with the car. you can get parts for it cheaply and it will go one with standard brackes if you can find them. every hearse has the same size aulternator on it. that beig said it ain't right. but if just like the electronis points set up if i could put this small aulteranator in the case of the big one so you could not see it I would. there are right now a lot of the small car type being put in old generator cases and installed in 20s cars in every car show to day. the look like the old and operate like new. but to do this might take more then the 300 to fix the origional one. just to change it over proberily would be a wash. here is thediferencei the 472 on the 69 ambulance and 68 combo. the combo used the standard gm aulternator. there is a lot tt have to change over just to put a cheaper aulternator on. but if you could hollow out the old one and put the new inside it then you would have something better the it was but the same. the cost would not be cheaper either way.

Default Anyone try these?

Finding my self in need of more amps as well on the Pontiac. I am running a 100 amp alternator, but looking for more. Found this as a match:http://www.powerbastards.com/proddet...FY4-Mgod-GwANQ

There is nothing wrong with converting to a modern alternator Most modern ones are more efficient and steal less HP. Also they are internally regulated so no external regulator. Paul is 100% right pulley alignment is important for belt and bearing life. This can usually be done shimmng with washers and a keen eye. In todays world 100 amp is a bit wimpy I would go with at least 140 amp. Just a question what does a $3000.00 AC rebuild consist of? Seems to me to be the rip off of the month.

I didn't realize that correct 145 amp alternators were that difficult to come by. I have access to 4 of them that have been rebuilt at $100 each.
