Jacques, Comandant Cousteau was a great man and a pioneer in see exploration,I watch al his videos when I was a child.
Do you also wear a red wool cap?

Looks more like the pull rod is flexing, should it have a bend in it? They work better if they are straight.

Hi Harlé

The video sure helps explaining the problem, it does look like something is out of line. Not having Ford it will take look at the manual which I did when I looked at the manual found that clutch assembly is not unlike the whole setup in my 49 Lincoln which basically has a Ford Truck engine.

It does in deed look like something is bent, worn or out of line.

Check my logic guys

7508 Bushing on both sides, as the load is all forward on drivers side and mostly backwards on the passenger side would tend to wear on one side.

7510 Shaft with even the slightest bend would make the lever arm 7511 look like it was bending as rotation. This shaft could be bent if the linkage 7531 up to the clutch peddle was allowed to over travel. Is it just a trick of the photo that your linkage looks like it has been welded?

You guys with the Fords will have to step in on clutch adjustment how you set it up so that it disengages near the top of the stroke yet the peddle hits the floor/stop before you are trying to over rotate the fork shaft causing it to bend.

If all of those parts are OK then check the pins 352581-S are they worn or have the worn the shaft holes to allow play.

Keep us posted on your progress.

Cheers Phil

Hello Harle,

I looked at the video, good suggestion Phil and as Richard pointed out the pull rod seems to have an excessive bend in the middle which is causing it to flex when under load.

I looked and the one on my truck and the spare one in the attached photo and they are mostly straight except at the clevis ends where they are slightly bent.
I assume this is to allow for the two levers not operating in direct line with each other.

Also Harle, yes, the red wool hat was his trademark, but I haven't started wearing one just yet. Maybe as my hair gets thinner I too will don a red woolen hat. I then might get more done in my cold garage in winter too.

Cheers,

...maybe it's my eyes but do I see a flat metal strip added to the rod..... in the end nearest the pedal........ as if there was a bending problems before and some one tried to reinforce the rod by welding a strapping.....which is now doing the S wiggle.

I suspect that once the rod is bent it would be difficult to ever get it perfectly straight again as the weak area would always remain.

The amazing part of all this is a video is being used to diagnose a mechanical problem thousands of miles from the source.

Bonne chance Harle

Hello Bob,

I certainly agree. This is one of the good things about the internet despite the recent Facebook controversy. People from three different nations using it to help out a person from a fourth nation.

For me, this video sure beats watching a cat playing the piano on You Tube!

Cheers,
