Someone here must have the correct #s from one our trucks.
I am most positive mine is changed, and would like to get the correct # so I could start my search for the correct part!

matt67350 · 12-26-2005, 01:23 PM

there is several on ebay. some even list the part #'s.

**truckdude239** · 12-26-2005, 01:56 PM

i would get an interntal voltagereg alt its an heck of an improvement over the ext. volt reg

Tx Firefighter · 12-26-2005, 02:31 PM

The way he's asking, I think he may be looking for absolute original correct parts for his truck.

RPOZ11 · 12-26-2005, 03:40 PM

Thank you Texas!
Just saw an 837 go for 1700.00+ on the BAY!!!!
Man O Man!
This hobby is getting close to out of my reach!!!!
If the Camaros get any higher on the parts, I just may end up with my truck and sell the Camaros!

RPOZ11 · 12-26-2005, 07:44 PM

Sooooooooo....

Anyone out there with an original truck that still has the original alternator?

LongHornDude???????????
Any thoughts on this?

**Joesjunk** · 12-26-2005, 09:06 PM

I have a 72 3/4t BB with 60k miles on it. I think it has the original alt on it still. I will try to look at it for you. I also have a 41k mile 71 with a BB. Would that be the same #??

RPOZ11 · 12-26-2005, 09:12 PM

Could be but I am sure the year date will change!!!
I picked up an alternator and I think it might be the right one, but I need to determine this through our threads here on his!

Has this site ever thought to have a restoration tab?

GMC Jim · 12-27-2005, 12:03 AM

1971 Chev Chassis Serv Manual lists following :- Model No. 1100566 ( Base - All C-G-P-K Models - 37 amps); No. 1100567 ( RPOK 79; P20 - 30 Models - 42 amps); No. 1100842 ( PS 20-30 CS - KS 10, 20 & 30 Models )

RPOZ11 · 12-28-2005, 12:52 AM

How about this # :
1102452
2C23 date code
37A

What would this one be?

**Joesjunk** · 12-28-2005, 10:52 AM

I looked at my 71 BB and it has been changed, but my 72 BB looks original. Where are the #'s at???

RPOZ11 · 12-30-2005, 01:36 AM

It's on the aluminum housing's outer shell around about where the upper bracket is....

68 50th · 12-30-2005, 09:07 AM

My parts catalog lists for 72:
72 All, Blazer (non-integrated) 1102459 42 amp (Delcotron) (Exchange Item)
72 All, Blazer (non-integrated) 1102455 61 amp (Delcotron) (Exchange Item)

The one in my truck is a 1102455 61A date: 2B21
(The title and VIN on my truck says 71 but all details that is different between 71/72 makes me think it actually is a 72)

RPOZ11 · 12-30-2005, 11:00 AM

1102452
37A

This is what I have.
Could this be the original alternator, and not the exchange item,
or what could I have then?

68 50th · 12-30-2005, 02:24 PM

I found the 1102452 Generator in my 1972 10-30 SERIES TRUCK SERVICE MANUAL.
Listed in the GENERATORS section:
Model No. 1102452
Applications: CA, KZ, GS and PS 10-30 Models.
Delco Remy Spec. No. 3395
37 Amps.

Looks like 1102452 is correct for a 72 truck, I believe the CA application code stands for:
Chassis Type C= Conventional Cab 2 wheel drive
Engine Type A= All.
I can decode the other application codes except the KZ (maybe a typo)but I think CA covers your truck.

RPOZ11 · 12-31-2005, 02:27 AM

Sweden!
and we get our info from a site member from SWEDEN!
Outstanding!
Thanx for all the efforts.
I wish I had the book you have!
I think a first for these trucks to document this!

68 50th · 12-31-2005, 03:35 AM

Glad I could be of help.
The 1972 10-30 SERIES TRUCK SERVICE MANUAL are available from the sites vendors: http://67-72chevytrucks.com/vboard/a...t.php?f=3&a=10 , or e-bay:
http://cgi.ebay.com/ebaymotors/1972-...ayphotohosting .
I have also seen the GM Parts Division CHASSIS and BODY PARTS CATALOG on e-bay from time to time.
