Wanted 1970 Alternator

Jason,
The alternator you listed is for a A/C car. :TU:


Thanks,
Ron

 

"Or a non A/C car with HD cooling."

Jason is right again!!!!!!!

I think an 80 Amp was also available for police/response cars as well, but it was huge and uses entirely different brackets, etc..........plus might even require a different set of front springs.:laugh: Just teasing about the springs.

Ron.... I will be searching thru my storage 'ALT STASH' this weekend... all this interesting chatter funcuses me, SO, WHICH alternator DO YOU REALLY WANT ME TO LOOK FOR??

Wheelz, Tampa Bay

 

Wheels,
0B-- date code. if not, M9 or 0A is close. Alternator 1100761 37 Amp ray:

Thanks again!


Ron

 

Ron..I didnt make it to my storage where the ALTS are ...sorry. just too stink'n busy. I will try again at the end of this week..ray:

 

Wheel,
Thank you for the great communication! I am in the same boat lately! I am praying too!

Thanks for all your time with this issue!:TU:

Ron

 

Hereya go Ron! These are just a few 68-72 alternators I have in stock...the others are pre 67...

The ONLY alt I have that is even remotely close is this one:
1100774 55A 0 C9

1970, March, 9th ... If I read Duanes Common Date Coding Systems manual right, this would correct for a factory A/C equipped GSX perhaps? :Brow:

Hi Wheels,

I want to thank you for all your time in looking for the correct alternator I need, but this alternator is not correct for the car. I hope someone else can use it because this is a rare find. If you can, please keep in mind if you ever come a cross the alternator I am looking for. 1100761 0A or 0B date code.

Thanks again and I look forward to talking to you again!:TU:

Ron

 

Yes I believe it does. The build sheet cooling code is SJ for the car with a 455 4 speed with No A/C.

Thanks,
Ron

 

Can you post the thread so I may read it and the number of the post so I may review it. All I have seen is 1100774 is for A/C cars? I would love to read this thread.

Thanks,
Ron

 

Jason,
I want to thank you for pointing that out. I never thought to check to see if it had heavy duty cooling. Thanks again!
Would the date code be correct for the alternator wheels has 0C09 be the correct one for my build date 3/9/70??? Same day??? Does your 55amp have a double pulley on it or a single?

Thanks,
Ron

 

If you have a build date of 3/9/70 then you should be looking for an alt that pre-dates it by 4-6 weeks.

Wheels alt would be perfect for a mid-late April 1970 built car.

"SJ" is the radiator code, and I have seen these on 4-speed cars before. (I think we went roundy round about this on Jason's car on a previous post.)


According to the assembly manual if your car came with HD cooling, regardless of engine size or trans type, the radiator should have been a "SW" larger 3-core.

Reviewed 1/2 dozen stage 1 4 speeds non AC or 455 AC cars and build sheet called out SJ. So is the build sheets wrong or assembly manuals wrong ?:bla:

DL,
I would say that we don't have all the revisions on these sheets to tell exactly what was going on at the time the cars were built....................also, if the Production plant did not have the smaller radiators in stock they would have substituted (up-graded) to one of the larger ones. Same thing goes with the alts and other parts.

The assembly line doesn't stop, and as I have always said, just because a car was supposed to be built that way does not mean that it was.

I have seen many examples where options were either left off or added to vehicles.


I also know of a few vehicles that went all the way thru the assembly line with incorrect parts. These cars were tagged, and when finished were set aside until the right parts were available and installed. ( 3:64 posi rears on the early built 1970 cars comes to mind) Again the line never stops...........

You want to talk about inconstancies with paperwork, you should check out the tire sections. They changed availability so often I think the engineers gave up trying to reference all the changes.
Duane

 

I guess the best way to figure out if this particular car has HD cooling is to see if it has the AC style pulleys or not.

All HD cooling cars should have the AC pulleys.

Then the question of why it has a "SJ" and not a "SW" rad comes back into the picture.


Now, going back to the book,
I was told by one of the Buick engineers that you are supposed to read the chart (Page 11-4.3) from the top down. Then the first radiator that fits your parameters is the one you got. For a 70 455 Manual non-AC car (non-GSX) that would be a "SF" rad. The next one down (that would fit this car) would be the "SJ" rad, and (further down) if it included HD cooling it would be a "SW" rad. (The revision block shows this page as being done on 4/14/70, so that is as far as you can take this.)

I personally have never seen a "SF" radiator, and know the "SJ" rad is quite common, as it was also the specified rad for a 350 with AC. So maybe it was substituted with 2 added Auto Trans plugs. I do know Buick built few 4-speed cars, so maybe it was a cost cutting thing due to stocking costs, who knows.

Anyone want to go back in time to ask? If I go back I would rather go a few years earlier and stand next to the grassy knoll. That is the question I would like answered.
