Reply to "throw out and Clutch Pedal linkage"

YES thanks for the excellent pic. I was able to count pixels to verify some dimension. The video was also good.

THANKS for providing your clutch stroke. 5.25" is a little less than I was expecting to get full MC stroke of 1.25” (but I am using the arc and not straight line measurement)

Would you still have the old arm to provide that "C" dimension on my 2nd post. Without knowing what the original ratio was, I can’t tell how much better this is.

Using your angles, would have the clutch pedal adjusted to start about ½” on my graph. This would be a “fast” take up (with a harder to push pedal) before leveling out with a ~7:1 ratio. To get the full MC stroke, I calculated pedal needed to go to 7 ½ on graph (so about 7” pedal ARC)

Here are the measurements I used for calculations; I figured “to a tenth” was good enough just to get an ideal of how the toggle works
a 2.6
b 1.4
c 1.8
d 3.8
e -1.3
f 1.6
g 2.9

The calculations were to model the red links as a four bar crank-rocker and the blue as an offset slider crank mechanism.
