Have been finalizing the clutch linkage on my slant 6 and A903 combination in a 60 Valiant and have a quick question.
Does the range of motion look right? The clutch pedal bottoms out to the floor.



The clutch pedal height seems low as it is lower than the brake pedal.

I know it looks like a hot mess but I am currently replacing some of the rusted floorpans and that is a home made shifter. This poor thing came missing a lot of parts including all of the clutch linkage except the z-bar and only the trans linkages
 
That much throw looks short to me. I can get you the measurement off a 66 Valiant later today, it's also a slant with a 903.
 
You only need ~.080 clutch departure for normal use. Reset the freeplay to .5 inch. Then install two .080 or thereabouts feelers between the disc and the flywheel, at about 180* to eachother. Then have a helper depress the pedal until you can easily withdraw the feelers, then shout stop. Then go see where the pedal is. If you have more than .5 then you can restore the .5 that I asked you to remove. If not, then leave it; because if this is a streeter then the .5 is enough freeplay to compensate for at least a year of disc wear, in occasional use.
 
Well there is another issue I guess.
I read my service manual and I also saw the setting for ½" of free play; I currently have absolutely zero free play at the clutch pedal.
The clutch pedal at rest seems low and if I adjust the clutch rod for ½" free play the pedal is even lower when it engages the clutch fork and thus the travel is even less.
Some pics...
First the over center spring. It came from a 66 Valiant and the two pronged hook is hand made.

The oddball trans fork push rod is made up from several spares from my tool box.

The clutch rod is also from the 66 Valiant (along with some D100 parts and miscellaneous items).

The clutch pushrod was from a van and I just set it in place to mock up the exhaust.

So the questions are: possible issues with the over center spring? The car never came with one and looking at the above pic there are no witness marks that indicate there ever was one. And as set up you can see it doesn't look aligned at all. I was going off pics for the hook since I didn't have one and the one from the junkyard 66 wouldn't line up.
Maybe I need a longer clutch rod that positions the pedal higher?
Maybe a combination of the two?
 
I was thinking about this during some free moments today. You mentioned in the first post you didn't have all the clutch parts to start with. I was thinking if you had to mix-and-match parts to get this working, there may be a geometry issue going on. If levers and arms and so forth are too long/too short or pivot too far/not enough, it can throw all this stuff off.

Now that I'm home I see your post above, I wonder even more if this is a factor. I'm not enough of an expert to weigh in at this level, but what you're describing sure sounds like a hardware/geometry possibility to me.
 
So I am thinking after looking at some other transmission videos online that the motion isn't that bad.
Once I get the linkages sorted and adjusted I will have to try it on the street.

I can't see the pics, sorry man.

Nothing? Which browser are you using?
 
I think it's because I use Chrome and the images are hosted on Google Photos.
I tried IE and got the little X for them.
