Starter/Solenoid Combo for 1956

[John C.]

Hi,


I just received my 6th edition JG 1956-1957 and it lists only one starter/solenoid combo for 1956:


Starter - 1107627


Solenoid - 1119767


In the past, I have read discussions stating that there may be other legitimate pieces such as the use of the 789 solenoid....has this all now been settled?


Thanks!


John

Re: Starter/Solenoid Combo for 1956

early '56 came equipped with 1119767 It is listed in 56 parts book
later '56 was equipped with 1119789 It is listed in '57 parts book
Part of the reason for change was the fact the early style solenoid would sometimes overheat causing it to continue to run.
Cannot answer your question re: new judging manual.

Hi David,

I have a May FG motor, would that be considered early or late?

Thanks!

if you are looking at a 56 parts book I would think that a early solenoid would be a august, September, and November of 55. also the 56 chevy part books are dated effective april 1, 1956 so anything after that date can not be verified by using that book. late august or early september 55 is when most production of the 56 cars and trucks started. corvettes began production in January of 56 and unless someone can verify having a 56 corvette without a rubber boot on the solenoid then I would think they all came with a 789 solenoid. 767 solenoids do not have a provision for the boot.

Hi John,


My head may explode! So, are you saying that a 1107627 starter with a 1119789 solenoid may also be correct?


Jeeze, could the judges say sorry, not in the JG?


Thanks!

I would expect a judge to go by the judging guide and only accept the 767 solenoid. your best bet is to email the 56-57 team leader. from articles i have read a rubber boot is used on the 56 corvette solenoids. if this is the case ask the team leader how the boot is suppose stay on the solenoid since a 767 solenoid has no tabs to keep the boot from moving.

Interesting.....I emailed a John St Peter, but so far no response.

BTW, the starter I removed from the FG motor was a 1107649 starter (1956 Chevy Passenger Car - 8 Cyl. w/A.T) and it had a
1119789 solenoid - Date Code 5M14....I know, not possible to claim it was the original starter!

OTOH, what is the outside physical difference between a Chevy 1107649 starter and a Corvette 1107627 starter other than the rubber boot on the Chevy 1119789 solenoid vs the non-booted 1119767 solenoid on the Corvette starter?

Each internal part has the same part number except the Drive, which is D2002 for the 627 and D2006 for the 649.

Thanks!

Re: Starter/Solenoid Combo for 1956

Solenoid # 1119767 was used on EARLY 56 corvettes. The problem of sticking and allowing the starter to continue running was experienced at Sebring in Feb./March '56. This problem was brought to the attention of Chevrolet Engineering (Mr. Rosenberger) on April 9, 1956. I am unaware specifically time wise when this problem was addressed but I am fairly certain it received attention. The issue with the boot was another problem. Both issues were resolved in '57 with the drive end housing being extended to enclose the solenoid completely.
Reference to the printing date of the '56 parts book is correct. I hesitate to use parts books as a reference point but in this case I did so to show the 1119789 solenoid was in fact being used in '56 even if it was introduced too late to publish in the 56 parts book.
I will stay clear of the JG manual issue --- but would agree if the car is to be judged you better bring your proofs. As for the recommended date for the 1119789 use, I do not play the dating game. Use the April 9, 1956 Engineering letter as your starting point and go from there.

FWIW the change over from solenoid # 1119767 to solenoid # 1119789 in the P&A 30 was 7/1/56. I have only seen the #1119789 solenoid used on last 100 or so produced 1956 Corvettes.

Re: Starter/Solenoid Combo for 1956

Thank you David, John and Gary.....so, it would seem that the *easiest* way out, especially as it relates to the judging and the JG, is to simply use a defective 1119767 solenoid on my May FG motor and be done with it.

I would have placed the 789 solenoid nearly a year before the date you mention. the only solenoid mentioned in the 56 parts book is 1119789. so that would tell me that at the very latest any starter dated after mid april, 1956 would have a 789 solenoid. I know that the booted(789) solenoids started appearing in late 55 corvettes and the early 56 car and truck line.

then are you saying that a boot did not appear on the solenoid till the last 100 1956 corvettes? I was under the impression that all 56 corvettes had boots on the solenoids? the difference in a 767 solenoid and a 789 solenoid is that the 789 has the tabs to retain the boot.

[Gary C.]

Re: Starter/Solenoid Combo for 1956

The #1119789 did not appear in any P&A 30 parts supplements until the revisions date 7/1/56 and the description states with boot.

Checked all the parts revisions prior to the P&A30 dated 4/1/56 and there's no mention of 31119789 solenoid.

Don't have any knowledge of what was put on trucks and passenger cars. All I can go by is what's listed in the P&A 30 books and supplements.

Re: Starter/Solenoid Combo for 1956

While we are here.....I just tested the 649 starter and 789 solenoid and they both work....what is the solenoid piston/plunger with the clevis linkage called and is it a part that is available? It works, just looks funky!

Ok......I guess it's - Plunger, w/link - 1926647


Thanks!
