Accelerator Swivel Bushing; gm 3707713

[Gary B.]

Can anyone tell me which of the two styles of bushing is correct for the carb swivel bushing for a '66 L79? One has a narrow flange and one has a wide flange.

Thanks,

Gary

Gary,

About 20 or 25 years ago I bought a complete 1966 Chevrolet Pass. 327 engine w/Roch. 4bbl from a salvage yard in Orange, MA, for $25. All the components of the engine were original (carb, heads, starter, fuel pump,etc.). I still have the carb rod with the original 3707713 sleeve stored in a box in my garage attic. As best as I can remember the 3707713 sleeve has the narrow flange but when I get a chance I will retrieve it to be 100% sure. In the summer it is quite warm in my garage attic so hopefully someone else will chime in with a definitive answer.

Gary,

According to Chevrolet Parts History GM # 3707713 was replaced with GM # 3866271 in November 1965. I'm sure that the 3707713 sleeves were still on the assembly line for a long time after November 1965 and were used until they were gone. Your photo of the wide flange sleeve looks more like the 3866271 sleeve. Enclosed is a link of a NOS 3866271 sleeve that I found on the web.

Gary,

I just checked my 1966 Corvette as well as my 1980-1995 restoration documentation (yes it took 15 years) and I did install the 3866271 wide flange sleeve back in the early 1980's as I could not buy a 3707713 sleeve since it was discontinued. Where did you get your information that the wide flange sleeve was GM # 3707713?

David,

I know someone who is selling the wide flag bushing and he claims it is correct for '66. So I just assumed it was 3707713 based on the part number in my '66 AIM. But in fact, I don't know if the wide flange part is indeed 3707713. It could be 3866271.

Gary,

Without a doubt the narrow flange is correct for a 66 Corvette!

It is available in reproduction for very little.

Gary,

I am pretty sure that the wide flange sleeve is GM # 3866271 as that is what I installed on my 1966 during my restoration from 1980 to 1995 as that was the sleeve that was available from the Chevrolet dealer part department. I'm not sure when the reproduction 3707713 sleeves were first made.

Dave,

Given what JR says, do you think your '66 originally came with the narrow flange bushings?

Gary

My 1966 did not have the original engine but I believe that the narrow flange sleeve would be correct.

Re: Accelerator Swivel Bushing; gm 3707713

The original accelerator rod-to-carburetor lever bushing had the WIDE flange, which was to be oriented on the same side of the rubber grommet as the spring end or cotter pin that retained the rod; The purpose of the wide flange was to prevent the sharp end of the return spring or either end of the cotter pin from tearing up the rubber grommet.

John,

Well now I'm confused. Are you saying that all C2 years used the wide flange bushing? At both carb and nearer to firewall locations?

Gary,

Quit being confused and direct this question to the 66 Team Leader. He is probably home from the national by now.

Gary, I have a '66, 350h.p. that has the narrow flange bushings at both ends of the rod. It is VIN 11,xxx. The car is in survivor condition and has been off the road since about 1970. Perhaps there were some bushing changes during the year.
