59 FI Throttle linkage to bell crank

[Al R.]

The gap between the Fuel Injection bell crank on my 59 and the accelerator bracket is so small that I can't get the rod installed between the 2. Is there any adjustment on the accelerator bracket that attaches to the pedal pivot rod that extends through the firewall that would allow it to be positioned back toward the firewall to gain more clearance?

Al, Is it possible for you to post a pic? Repro parts may be contributing to your problem.

Sounds like you have an accelerator rod issue. How about a pic of the rod also. Your problem is not a typical one. May be resulting from combo of repro parts and original. Or incorrect parts. Could be the bellcrank. Might be the accelerator return spring bracket. Maybe you have it facing the wrong way.
Can't help you anymore without a pic. If you can't post it here send me an email with the pics. johndegreg@aol.com
Probably an easy solution. John

John has you covered, but just to answer the question about any adjustment of the pedal lever to accelerator bracket connected to it.....

There is no adjustment. The accelerator bracket has a pair of half moon holes and a pinch clamp end(A name guess as I don't know the exact term), which fits over the pedal lever mating half moon shaft. The 2 are held together with a pinch bolt. No adjustment possible.

Another possibility is that the firewall insulation or thick carpeting is preventing the pedal lever from going to it's full IDLE and WOT endpoints.

Richard, the pedal will go WOT, so that's not an issue. I thought that was correct on the way the bracket attached. Thanks for the response. John, I will try to e-mail pictures to you on Monday. Thanks, Al

Al, A typical repro bellcrank to air meter rod has the incorrect bend/angle to it. They have to be massaged in a vise with a dead blow hammer to increase the angle of the bend.
Using a repro as is will result in only partial acceleration as the geometry is thrown way off.
But this doesn't appear to be your problem but it may be others.. John

John, did you get the pictures my daughter e-mailed tonight?

John, I had to buy a repro bellcrank to AM rod. Here's a photo.

Am I going to have the same issue?

Thanks,

Re: 59 FI Throttle linkage to bell crank

Yes I did. Try adjusting the swivel to get more action from accelerator pedal. Back off on the threads-toward the firewall.

Re: 59 FI Throttle linkage to bell crank

Rich, You should be fine. Not mentioned in most catalogs is this. The '57 air meter to bellcrank rod doesn't have the angle bend that the later years do. John

If the bellcrank swings too far forward toward the air meter this is not good. Increase the angle of the bend so the top of the bellcrank is pointing toward 12:00.
