Generator Arm Trivia C1

Re: Generator Arm Trivia C1

Joe -

Here's the story. In the photo below, taken in 1955, it shows passenger car V-8's on the shipping dock; note that the generator brace is pivoted back over to the passenger side for vertical shipping rack clearance. At the assembly plant, they loosened the water pump bolt, pivoted the brace back to its normal position on the driver's side, installed the generator, and re-tightened the water pump bolt.

They couldn't pivot it over to the passenger side on the Corvette engine, as the generator brace was fixed in its normal position due to its going through the slot in the motormount bracket. As a result, the end of the Corvette generator brace stuck up above the top level of the engine rack, and was frequently bent/damaged when another engine rack was stacked above it. That's why Engineering made the change to the Flint V-8 plant Bill of Material in early April, 1955, to re-allocate assembly of the Corvette generator brace from Flint V-8 to St. Louis. The same brace (3704884) was used on passenger and truck engines, and it remained installed (and painted orange) at Flint V-8 on those engines.

Why would the part number 3704884 be used to order the brace from the parts book then come with a in-bossed number having 3760364 in it?

Re: Generator Arm Trivia C1

Here is what we talked about a while ago , he is using a 1961 parts book saying it's used on 55 up but that's why you cant use the parts book to sell parts or buy using a parts book.

Roy, I don't have it figured out but I can see that service parts would be black. I guess more research of survivor cars needs to be done on the orange / black corvette brace question. I bet there is paperwork somewhere documenting the problem of the Corvette braces getting bent in storage.

I have some paperwork documenting other problems like that issued at the St.Louis Corvette plant and the actions taken and implemented...including the original document recommending that Corvettes be shipped by rail and the follow douments that put rail shipment in place and the results.

Can you guess the year?

Re: Generator Arm Trivia C1

The year 56? Like you said more research needed on the brace , most anything over the part department came black or un-painted , but many parts will never be known

I dunno anything about C1's but I can tell ya for sure that a 3760364 was never used in production on a 55-56 or at least early 57. Bet it was released for late 57 or possibly 58 and was used as a service replacement for 55-57.

How do you know for (sure) that a Corvette never came with 3760364 arm , I had many 55 to 57 Corvettes and they all had it, even the original 55 I posted of the engine shows it.What do you know that many don't?

Betcha $20 that the 3760364 never existed in 1955. Betcha another $20 there wasn't even a print for that part at that time.

I'm not looking for an argument or to make or lose money Just your answer so I can trash my 55 brace and get what you say is correct ( waiting)

Roy, if I had a 55, 56 or 57 AIM, I would look at the number for the brace. The numerical value of the 3760364 number is way too high to have been original for 55-56 and probably 57.
Look in a 1955 printing of a parts book and you will not see any part numbers anywhere near that value. Most will be in the 3705xxx range, much lower than your 3760xxx number.

Many parts are replaced in production over the years and later printings of parts books will often show the newer/numerically higher number as being correct for earlier models.

Most mid 57 part numbers are in the range of 3745000 but 3760xxx didn't appear until probably late 57 or early 58.

Numbers increased, numerically, as time went by in the 50's and 60's.

There's no secret in the number itself, other than it's numerical value.

I think the 55, 56 and 57 AIM's are available. What part number is shown for this part in these manuals??? Bet the 55 part number is somewhere around 3710000, much lower numerically than your 3760364.



There is a block of numbers that throw a wrench into the works though. For, I believe, 1953, many numbers were way out of sync with that system. As I remember, the 1953 numbers for that era started around 3838000?? I don't know why that occured but it stopped soon after. The system then went to 369xxxx and eventually into the 3700xxx range.
Kinda out of my range so I may have some of the details incorrect for the 3838000 series. May have been 1954?

David that is the #0364 design , what Michael is stating I know nothing about , but again your's is correct same as my 55 , so I don't know what to say to Michael's statement.
David I see your 57 also has the real washer FIRST design red top and see nothing wrong (great 57 you have)

Re: Generator Arm Trivia C1

Doesn't anyone have a 55, 56 or 57 assembly manual? If so, I'm sure we can find the correct generator brace part number.

I'm guessing the 3760364 first appeared in late 57 or 58. Not 55 or 56.

Michael ! I'm not trying to make you realize that 55 and 56 ,but not a early 56 used the 0364 arm,the original pic. Here and John's pic. Of 55 engine above shows them being used . I don't care what a part's part number is ,I care and show what a part's design looks like. Again others can argue numbers
The arm I first showed having the numbers is used on 55-57 RIGHT the design is correct RIGHT it came from some where RIGHT

The brace that you show in your first picture in this thread is not the same as the one in John Hinckley's pic of new 55 engine. Both in your pic have more of a bend.
Also, the brace in the pic of the 57 That David Smith posted appears to be different than the ones in your picture.

I don't understand why you won't post the number from the 55 assembly manual. I KNOW you have to have one. Why are you keeping it a secret?

Also, the two braces in your very first picture ARE the same. One is still in it's original configuration and the other has obviously been bent in the area of the adjustment slot.

The 3760364 brace was also used on all 58 to 62 passenger cars. It was not a Corvette only part and it's not rare.
