1939 was the last year for the steel end plates and the rear plate with the gasket and cover that takes 3 screws to hold it down.
948 R was the Delco # for that generator.
1102667 was used in 1940 and up and had aluminum rear plate and aluminum front plate. Chevy always used the aluminum plates in those years. GMC and International Harvester trucks would have used cast iron plates that looked like the aluminum ones on the Chevys. There were several aftermarket companies that reproduced the front and rear plates in the 40s and 50s and they reproduced the front plate in Aluminum but the rear was done in cast iron.
1939 was also the end of the shorter straight case as the 1102667 was the first gen. to use the longer case. 1909109 was the original Delco # for that aluminum rear plate and may have been superceeded to others but I didnt look into it that much.

So Ken, now ya got me all confused, those numbers don’t jive with the generators I have on the generators on the bench here or the numbers I have access to. I did some searching through the Chevy parts books this morning to try to make some sense out of it..

This is the generator that is tagged “Factory Authorized Rebuilt Generator” Mod 72U-11F2 Code. Pic: http://rides.webshots.com/photo/2526278320098611668YDvrlt
It has the one-piece aluminum CE end frame with the blind hole for the bushing. And a cast iron DE end frame. Parts book shows the (72-U) as 1940-48.

This is the generator that is tagged “Delco-Remy” Anderson, Ind., Automotive Electrical Equipment. Model 1102667 Serial 75517. Pic: http://rides.webshots.com/photo/2869306830098611668cphpus
It has the cast iron CE end frame with the outside cover plate for the bushing. Thru a couple of revisions the Parts book shows the (9-U) as 1949-52.

So how can the second one tagged 667 have the cast iron end frame if 1939 was the last year for it? And if the 1102667 was used from 1940 and up and had aluminum CE and DE end frames how do you account for this one having both CE and DE end frames of cast iron?

Parts substituted - 1102667 Use 1102672 rev.date 4-1-49, 1102672 Mix w/1102737 rev.date 3-1-50

Chevrolet Parts Book listing,
For the 1940-48 ALL pn.1102737 (72-U)
For the 1949-52 ALL pn.1102719 (9-U)

Yes, the 1909109 CE frame appears to have been replaced by 1913990 fits 1938-52 ALL. It doesn’t say but it sounds like they just replaced all the cast open-ended frames with the aluminum frame w/bushing. The Delco-Remy service bulletin says that you should replace the aluminum frame if the bushing is worn.

Ps. Also to I made some corrections to an earlier reply concerning the armature thread, taint as bad as it sounded.

I was afraid of opening a can of worms. Your using Rebuilt numbers and...the Factory Authorized Rebuilt Generator tag on your gen. states just that. A rebuilt generator. Delco had, and still does, of course they arent Delco anymore, use independent rebuilders to rebuild for them and just like any rebuilder back then or today they used whatever worked. They werent worried about 100% correctness and when done they issued it a Delco Rebuilt number instead of the original 7 digit number that was on the original tag. As for the one generator you have that does have the original 1102667 tag on it...well, its simply wrong and has been replaced at some point. Those housings were never used on that generator. I have the original Delco books from the 1930s up and to double check myself I looked up every generator from 1938 up until 49. 1940 started 1102667 with aluminum plates, I know this by looking up the break down on the generator and looking up the individual plate numbers, hence the 1909109 comm-end plate number. It never changed through the years except with the 1913990. If Delco issued a service bulletin stating to relace worn bushings or mounting holes with cast iron end frames then that may be so...and would be correct for a "factory rebuilt" generator, but not for an off the showroom floor generator.
As far as the other numbers are concerned, 1102672, 1102737 etc. there may have been minor changes in pulley diameter or belt width, may have even been a slight amperage change, but they all had the same end plates. Im not in front of my books at present so cant verify exact differences in them.

I really hate getting into these issues with folks as I know everyone would like to think they have the 100% correct generator. I just did a restoration for a customer that inherited a 55 Chevy truck and assured me the gen. and starter were original. 12 volt mind you. Turns out the starter was a 47 6 volt starter and the generator was off of a 59 Chevy car with power steering pump mounted on the rear of the generator. Of course the pump was gone but he was wondering why the shaft was sticking out of the rear of the generator.

Denny,
This explaines why you were asking about the gasket on the rear plate of the generator!!!!! Makes since now. You have the cover over the bushing. Sorry for the confusion.

Yeah Woody, you really opened a can of worms!!!!
Naw Ken, I taint saying anything is original on the truck. I know the generator that was on it when I bought it was a rebuilt, gave ya those numbers already. And the Iron frame one I bought a few years ago before I even had the truck. I was going to make a replica Zenith Wind Charger from it to display with some of my old radios, never knew at the time I would be getting back into working on these old rust buckets.
I gotta say this though, you can sure get $%#@ up looking and comparing numbers in the different Chevy parts books out there. Seems like they are all written people with different ideas. And I wonder if there are really any VCCA judges that can sort it all out.
And I hope you learned something from this Marty, I think I'm just a little more confuesed than I was?
Fin!

Denny, Keep an eye out for a "Master Parts Catalog" from Chevrolet that covers the year(s) of your truck.Then you avoid the confusion of actual part numbers.Mine was probably the best bid I ever won on EBay, but I've sen them at swap meets too.I'll add also that this forum has been particularly useful to me as I am completeing the refurbising of my 6V generator.Thanks.
