How many pounds of force do you need to pull the clutch cable in a car ?

In terms of pulling force needed to disengage the clutch (like pushing the clutch pedal down) But I need to know how much force on the cable, not the pedal. Pretend there is no clutch pedal and you have to pull in the clutch cable with your hands.



Roughly how much would it be a:



Honda Civic/Toyota 4cyl



Honda Accord/Camry 6cyl



Ford Mustang/Pontiac GXP



Audi RS4/Bmw M3



Porsche 911 Turbo/ Ferrari F430?



Thanks!!!!!!!!!!!How many pounds of force do you need to pull the clutch cable in a car ?in trade auto class they teach the ratio is about 6 to 1.

so if that is true and it takes 30 lbs to push the pedal then

its about 180 lbs.



spring clutches are worse on trucks (bear trap)



one can find out exactly by measuring the arm on both sides of the clutch pivit (of the pedal assy) and then divide the two measurements.



like 2 inches and 12 would be 6 to 1 .

then using a compression scale measure the pedal pressure.

then multiply by 6 and you have an very accurate measurment.

or crawl under car with fish scale and pull real hard on clutch pivot with a come-a-long.

more difficult ( impossible for fluid hyd. cylinder clutch)



hope I have helped.
