Wondering if anyone with a 5-speed truck could do me a big favour and take some measurements on their clutch pedal for me. I'm setting up the stock NV4500 hydraulics in my '82 Chev K30 and I want it as close as possible to a stock installation for durability.

The measurements I need are:

Pedal pivot bolt to the pushrod pivot stud;

Pushrod pivot stud to center of pedal pad (where your foot goes); and

Total pushrod travel from fully released to fully floored pedal.

The top two measurements will give me the ratio needed to get the correct leverage, and the last measurement will ensure that I get 100% clutch release when I need it.

Thanks in advance!!

 

Bump for the night--maybe I'm ****, but it would be nice to know I'm getting the right geometry . . . .

 

I can't help you on the full travel because I'm swapping over to a manual and the pedal assembly is sitting on my kitchen table, no master cylinder attatched but pivot point to pushrod stud center to center is 2 and 9/16 inches. Center of pushrod stud to center of pedal in it's travel is 13 and 1/4 inches. Total length, center of pivot point to center of pedal is roughly 16 inches.

Not sure if it helps, but standing the pedal bracket upright and measuring pedal travel stop to stop without a master attatched is 19", the pushrod stud only moves 2 and 3/4 inches through the whole travel.

 

THANK YOU SIR!!! Very much appreciated!!
