Ford cmp clutch question

[Jacques Reed]

Hello Harle,

Your problem could be wear in the clutch release shaft and their bushings.

The shaft can wear appreciably as shown in the attached photos along with their bushings allowing the shaft to twist in the transmission housing. Note the very noticeable ridges at the the bushing areas.
Years of civilian owner neglect is the probable cause if not lubricated regularly.

I replaced mine with NOS items but they should be available from Ford Flathead V8 suppliers.

Hope this helps.

Cheers

hello Jacques

Thank you for your interess, It's not easy to explain in english, That's not the schaft that twist, but the end of the arm.

I removed the shaft when I rebuilt the gearbox it looks great and was greased.

Hello Harle,

Sorry I misunderstood. Wish I had learnt another language, French, when I was in school but you do very well with English. My French first name is just my Father's admiration of Jacques Cousteau when I was born but I know no French.

Your clutch lever on gearbox twisting seems unusual. Is it actually twisting the lever, or is it just moving on the end of the shaft?
I have looked at mine and noticed there is some sloppiness with the lever on the shaft end. It can wobble (twist) slightly.
If the actual metal of the lever is twisting that indicates a very high stress on the arm and seems like something is very wrong. Eventually it will break from metal fatigue. Sorry I cannot give you a definite answer.

Hope this is of some help.

Jacques, Comandant Cousteau was a great man and a pioneer in see exploration,I watch al his videos when I was a child.

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,
