For the 1969 Ford Mustang 250 carb linkage

Post #1 by xctasy » Fri Mar 15, 2019 8:39 pm

Someone recently was wanting to know how the 1969 250 mustang linkage was set up.

It bolts on the rear passenger side exhaust boss bolts that all C8 (1968) onwards castings seamed to have.

I used this C3 1963 era head to bolt on the later kickdown linkage

The 1969 Mustang accelerator linkage uses the kickdown linkage mounting plate

For the 1969 Ford Mustang 250 carb linkage

Post #2 by chad » Fri Mar 15, 2019 9:47 pm

Is that the same bent plate (not as rusty looking as seen in last 4 pic) to the left of the 1st pic, touching the rear lift pint, has 2 lower bolts into the log & a longer round rod threaded thru as in the last 4 pic? I understood frm a post last wk here that the C4 kick down goes in there too. That this is only on the rigs w/a C4?
:?:
Thnx !
Got a name &/or part number for it?
Love 2 C the kick dwn & throttle cable/linkage on'em.

This shows (if it is a '63) a way longer run for this part than I was aware. Boy, alot more folks than I realized musta trashed them. I can't find one. That'n the 2 lift plates R on my search list...

It was on the manuals to, they just didn't use the kickdown hole. There was one on the 70 250 I bought and it was a manual.

Mine doesn't appear to have a # stamped on it. I think they are available. I seem to remember seeing them on one of the mustang parts sites.

Okay, this is actually quite simple.

The cable pendant throttle for 1969 is really the same as the Fox 1978 onwards system.

Varilux used a Lokar short cable conversion kit to mate a 69 Mustang pedal one to sort out all his Power Steering verses Tri power issues.

Being an ophthalmix product techncian sure helps train your eye for some simply perfect parts, but he'd read through a lot of basic literature, and came to his own conclusions.

Varilux wrote: I finally decided to bite the bullet and convert to a cable throttle. I purchased a '69 gas pedal, drilled a few holes to relocate the pedal mount, and yes- this was definitely a better solution. Additionally, the mount for the rear carb's pivot (the U piece I had fabbed earlier) provided the PERFECT mount for the end of the cable. For the first time, I was really really glad I had installed the 3x1. If I could go back and change any part of the process, I would have converted to the cable throttle as I was swapping the head. It would have probably cut at least 75% of the time from this project.

Here is how the big old 68 onwards bolted on kickdown bracket in the original post works in.

First years, about the advent of the 250 option in the Mustang (actually 1968 in some Falcon/Ranchero utilities, but released officially in 1969 in the Mustang) the Carter YF and then RBS carb was operated from the uphand passenger side position, but it was primarily run by a cable from the drivers pendant gas peddle.

Image

The issue is that on 69's, the cable stopped short at the passenger side, where the Kickdown bracket became the mount point for the rod operated whatever 1-bbl they ran. 250's with 1-bbl Autolite 1101 or Carter YF carb.

Then it got changed to a full cable about the Maverick era from 1969 to the end of the run in 78. The carb had a fully cable operated system by then.

Image

Now, the Weber 38 is just a rehashed 32/36 Weber or 5200 seriesHolley Weber, so what works for those earlier AUtolite 1100/1101/Carter YF/Carter RBS, works for a Weber 38 too.

Soo, simply, the 69 cable operates the old Autolite 1101/Carter YF/RBS from a cable and then to that big old kickdown bracket.


Its not well understood, and its even harder to find when all the posts in the forum at around Apr 09, 2017 are sequenced out of order...right back to 2003. But hey, that's why I do pictures. So you can see how simple it all is.

The throttle linkage and kickdown rod on early 69-70 Ford small sixes with the 250 carb before the RBS had the 9728 bracket as a throttle bracket.

When EGR was introduced, the whole actuation changed, but the part continuted to be mounted to the same two bolts at the rear exhaust manifold plane of the head.

Note the following

I'm certain there are high resolution pictures of bracket BPN 9728.

Just can't find em.

1969-1983 200/3.3 or 1969-1980 250/4.1 is whacha whacha whachawant...

Every C9 onwards head till E0 had the two bolt hole boss cast into the back part of the head, some early ones weren't drilled.


Image

from http://www.fomoco.org/tech-tips/how-to- ... t-numbers/


BPN
9500-9599 is the Carburetor
9700-9999 = Accelerator and choke control rods




As of the advent of the C5 and AOD, it went to a cable linkage on the YFA Big Sixes, but the er 1969-1970-1/2 Falcon, 69-73 250 Mustang, 69-77 Comete/Maverick/1975-1983 Granada/1975-1980 Monarch/1979-1982 Mustang/Capri/ 1978-1983 Fairmont/Zephyr all used a rod oprated version.

The internal BPN number will most likely be #9728

the 6 cylinder 240/300 F-Truck and E-Van system.

It should be under the Ford Six Performace old Classic in lines tech articles


Its not under 1bad6t.coms 170/200/250 69-77 Maverick rod operated kickdown linkages.

They were under this link

Both the Big Six and Small six rod operated kickdown bracket were similar, but not 100% the same.


The #9728 C4 and C5 kickdown rod bracket on the 1978 to 1985 non feedback carb F100/150'S has a similar musroom on the rod as the stock Small Six 1969-1983 rod operated kickdown.

post #7 pic 4'n 5 are different than these pic in #8 (they have a plate but it's only similar, a lill different too)

I C the RBS carb (I have here). The 'bolted to the log plate' has a rod linage that (might) go up'n over the back of the valve cover to connect to the gas peddle rod. I don't think the 2 pieces are used at the same time, no? Pined Hinged throttle link & 'bolted to log plate w/rod-threaded thru'. I need to havea pic on my desk top as I post abt this for clarity in viewing'n writing. Too late at nite 4 me to follow all this right now.
Back later, thnxs for posts. I just luv pic! Gotta stay w/it but laters...
