That Clovis and rod in your photograph is the same one as I’ve been trying to photograph without much luck.

Richard ...With your pedal all the way up, and now that I know what you've taken pictures of, about all that you can do is separate the pedal-end of the black rod from the clutch pedal and try unscrewing (counter-clockwise) the rod three or four turns at a time, re-assemble at the pedal end, and try it to see how it feels. And let us know how it's going, please!

the valve has nothing to do with the clutch release. it,s to control the vaccuum for the columba od . now if you have to much play with the clutch linkage all the way check the pins that go through the release fork & the lever that goes on the transmission release shaft.

The correct clevis pin for a return spring shows in the photos, but not a return spring attached to that clevis pin.

jimTN · 05-29-2022, 08:25 AM

I'll betcha there is a rod attached to that vac valve that goes to a lever on the dash that shifts the rear end.

I gotta do it : "clevis", not "clovis" (which is a city in New Mexico).

And also 'Clovis' refers to a Native American people that inhabited North America right after the last ice age.

That makes sense and it looks like a nicely made setup - will have to get one for a Columbia I'm finally starting to build for my 32 Cab. I just don't like the new 3.54 gears I put in the late 32 rear . . . just too boring for me around town and I don't go on the highway enough to really want to keep them. So I found a set of 4.44 V8-60 gears to build a Columbia from - which gives me a 3.20 overdrive ratio (should be good for highway cruising).

Once I start chopping, turning, milling and welding, will create a post.

In the southwest, explaining the city name.

A rare trivia fact that somehow jumped out of my feeble brain! LOL

I'd remove the linkage to the columbia valve.
Then set the clutch linkage. then adjust the columbia valve to suit the new clutch pedal position.

You don't want the valve interfering with a correct clutch pedal adjustment.

A bit like I said in post No.8

Mart.

Ricosan · 05-29-2022, 08:35 PM

Hope to get help tomorrow with clutch adjustment. Thanks for the instructions Coop. I’ll let you know how things turn out.
Thanks for the tip Mart. I guess I should lengthen the ss shaft at the same time as I lengthen the Clevis.

Richard ...For now, the stainless shaft's length is of little importance until we get the main rod correctly adjusted. I would just disconnect the SS rod for now and concentrate on fine-tuning the main rod. After your first adjustment on the main rod of 3 or 4 turns, you should be able to feel some difference, and be able to tell that you are headed in the right direction. Good Luck!

Richard, since the Columbia actuator is connected to the clutch pedal arm and not the clutch release arm, I don't think the Columbia adjustment will be affected. The clutch pedal arm movement will not be changed by making the clutch adjustment rod longer.

Ricosan · 05-31-2022, 06:14 AM

Hey Guys,

Ran into a problem. I don’t have enough threads left on the clevis rod. It looks like it’s adjusted all the way out. I need to replace this rod with one about one inch longer.
Can anyone suggest a source?

Hey Richard ...I was afraid of that when looking at your pictures. How long is your rod OVERALL? It should be FIVE INCHES long. If it is substantially shorter than that, someone has hacked on that one. 3rd Gen Automotive has the 5" rod, part # "EF-7521" ...$12 bucks!

If your rod is already 5" long, there is obviously a problem somewhere involving the throw out bearing assembly or the clutch release arm geometry. What you COULD do is get a longer piece of threaded rod, and use TWO clevises...one at the front, and another threaded-onto the rear of the rod that you have custom cut to whatever length you need, by trial and error. A second clevis WILL fit onto the clutch pedal if you use your imagination. 3rd Gen also carries the clevises, part # "B-7532"...$11 bucks! Coop/AMERICAN

They will be out of town at a Ford meet until Monday June 6!

Tubman, my bad, my iPad apparently doesn’t recognize some words. It changes “clevis” to “clovis” automatically while I’m diligently typing out the clevis.

"Auto-Correct" - You can learn to hate it.

I hope you get your clutch linkage squared away.

Bored&Stroked · 05-31-2022, 03:39 PM

Or, if you find that yours has been shortened, you can buy a grade 5 or better bolt of the same size/thread and cut off the front of your threaded rod and "extend" it with the new piece . . . welding the two together. I've done things like this on various vehicles in the past. You just need to know a good welder.
