    C2 BB Starter

    On page 138 of the "1967 Corvette Technical Information Manual & Judging Guide" - #3 (Yellow Cover), under Section 26. Starter System, it notes the following words: Straddling the solenoid on big block cars is a spring-tension clamp with a wiring guide on top to keep the solenoid wiring away from the exhaust manifold.

    QUESTION: I looked in the AIM and did not see this. The AIM shows a heat shield, but in looking at the archives from 2009, the BB did not have a heat shield (Joe Lucia noted this) . Would anyone have a picture of what this spring-tension clamp looks like (installed on their car) or perhaps a picture of it in the AIM or another reference that you might be able to share?

    Thanks for your help!

    Check out the Dr. Rebuild catalog under "starter". You will see a diagram of the part under their part number 2341202. Theirs is as close to the original as you will find and it will be NEW. Otherwise, you can go out to self service wrecking yards and find one. These were not unique to Corvettes.

      Bob,

      There is a nice photo of the spring-tension clamp (aka a clip in AIM) in the link below. The GM part number is 3906181 as shown in the 1970 Camaro AIM, UPC 12, sheet A7. The 3906181 clip also appears in my 1967 Camaro AIM, UPC 12, sheet A9. GM # 3856490 was replaced with GM # 3906181 on 10/7/66 as per the revision record.

      The 1967 Corvette AIM shows clip # 3856490 on UPC L36, sheet A16.

      Probably doesn't matter on a part you can't really see, but on a '70Z 418 starter.... 1) Are the screw's that attach the solenoid to the starter nose housing phillip's, slotted, or a hex head? (I have all three) 2) Also, just want to confirm the plastic cap on the solenoid is supposed to...

        I don't think the one shown in the Camaro web-site is the one used on Corvettes.

        While the 3906181 did replace the 3856490 for SERVICE, that does not necessarily mean that it also replaced it for PRODUCTION. The 3856490 was used well after 1967 for PRODUCTION.

            let's see if this posts a picture, they seem to have to be smaller than before the upgrade!

                  Joe,

                  The 3856490 and 3906181 clips apparently were not sold over the counter as per my October 1966 and July 1972 Chevrolet Price Schedules. You are probably correct that the 3906181 clip (with the extra "loop") was not used on Corvettes. The 1968 & 1969 Corvette AIM's shown a drawing of the clip (without the extra "loop) but no part number.

                  Apparently the 3856490 clip used on "early" 1967 Camaros was replaced with the 3906181 clip because the extra "loop" was required for some reason. Do you know what the purpose is of the extra "loop" on the 3906181 clip? The drawing in the 1967 Camaro AIM (UPC 12, sheet A9) shows the extra "loop" but not really used for anything.

                    The clip part number is shown in the AIM but not in UPC 6. It is shown in UPC 12, the electrical UPC. I checked again and the the 3856490 was used right through the 1982 model year.

                    I do not know what the extra loop was used for on the 3906181 clip. It might be that it had a use for some other-than-Camaro chassis application. So, why wasn't it also used on Corvette after it's release in 1967? That's a good question that I also don't have an answer for.
