Just a quick question i needed answered. I dont know for sure how to adjust the clutch so thats why i am asking...

So you turn the firewall adjuster to the right to loosen the cable tension and turn it to the left to tighten the cable?
Then you have to get under the car and take the cover off to see the tightness of the cable?

I read about having 1" of play in the pedal.....SO does that mean you can pull the pedal upward 1"?




Sorry for the questions im just tryin to get everything understood.
 
Turning left raises the pedal - increaseing the distance of pedal travel required to dis-engage the clutch
Turning right lowers it - reducing this distance.

You want to lower the pedal enough so that the pedal doesn't have to travel very long to completely disengage the clutch but you dont want to lower it so much that the clutch isn't copmletely disengaged.

Before I got the adjuster, my clutch disengaged at the top 1/4 of pedal travel (or about 6" or so from the floor), making the remaining 3/4 of travel wasted time between shifts. The hsop that installed it adjusted the pedal down so that when the clutch disengaged, the pedal was only about 2" off the floor.

I hope this helps.
 
You will know if the pedal is too low by a few different symptoms.

1) If the car is harder to shift even with the clutch pedal all the way down.

2) You smell burning clutch when you are sitting still with the clutch pedal down and the car in gear.

I never adjusted my clutch pedal this low but my first adjuster didn't have a jam nut and over time, the thing would rotate to the right, lowering my clutch pedal to the point where the tranny would grind at any gear change :fuss:

I was able to get my clutch pedal almost level with my brake pedal.
