Re: adjustable clutch cable
Don't know if this will help
Now would be a good time to define exactly what this "quadrant" thing is that people talk about. A quadrant is just ¼ of a circle. It is the light colored part of this clutch ratchet mechanism (actually appears to be more like 1/3 of a circle). It has little teeth on its perimeter and is held onto the clutch pedal shaft by the clip that is visible. However, the quadrant is floating on the shaft, as it is not splined to the shaft and does not directly have to rotate with the shaft (this is a very important part of understanding how the mechanism works).
The clutch cable comes through the "firewall" and attaches to the top of the quadrant, in much the same way that the throttle cable attaches to the throttle body. (Unfortunately this section of the quadrant is out of view above the picture.)
Again, think about what happens when you push the clutch pedal. The small ratchet mechanism assembly on the right rotates upward. This small ratchet mechanism has teeth that are meshed with the quadrant’s teeth, causing the quadrant to rotate counterclockwise, pulling the clutch cable. If you have difficulty visualizing all of the motion from the picture and this description, then it may be worthwhile at this point to look at it in your car and push the pedal by hand so you can watch what happens.
Now, let’s look at the two actual adjustment methods.
The first method is the one described in the owner’s manual. If you pull the clutch pedal back toward the driver’s seat, you will be rotating the small ratchet mechanism assembly downward. Looking at the picture, you’ll notice that the small ratchet mechanism will push against a metal "tab", causing the teeth of the small ratchet mechanism to disengage from the teeth of the quadrant. This causes the clutch to self adjust into the normal location. Many people (including me) find that this makes the clutch pedal position annoyingly close to the floor when the clutch engages/disangages.
The second method is the one you are most interested in and you can probably already see what to do if you understand how the whole ratchet/quadrant thing works.
hanging down from the quadrant is a part that is somewhat shaped like a hook. If you could push this "hook" upward slightly (basically rotating the quadrant counterclockwise), you should notice the clutch pedal move too. If you could push it up and keep the clutch pedal from moving then you'll probably hear the ratchet click as it engages one tooth higher, causing the pedal position to be "higher" (closer to the driver’s seat) when the clutch engages/disengages. One click is all that I usually do to make a big difference. However, most people have great difficulty pushing the hook upward because of the spring resisting that motion. It is generally much easier to push the clutch pedal in with one hand, hold the hook up with the other hand, then let the clutch pedal back out. This is the same effect, but you have a bit more leverage. Sometimes, just letting clutch pedal back out on its own doesn’t work and you have to pull it back slightly. It can be very difficult to adjust this way if there is not mushiness to the first part of the pedal travel. Hint: when doing this kneeling next to the car, I hold the "hook" up with my right thumb while working the clutch pedal with my left hand.
If you want the clutch to adjust back to normal, then just use the method described in the owner’s manual. It is a handy little reset while you are playing with whole adjusting mechanism if you think you are getting a bit carried away.
Don't go more than one click at a time without driving it to make sure it is where you like it adjusted. If it takes more than one click then maybe something else is not functioning properly. If it takes more than 2 clicks, then something else is certainly wrong. Also, this puts more load on the throwout bearing and can reduce the pressure plate clamping load on the clutch disc. I have adjusted it one click and have never experienced any problems. Just make sure you understand what you are doing and the consequences, as you are responsible for any adjustments you make.
Now, once you have it adjusted where you like it, you’ll probably notice that it easily self-adjusts back to normal if you accidentally pull the pedal back. The easiest way to cure this, once you are happy with the new position, is to slightly bend the metal "tab" that pushes on the small ratchet mechanism so that it no longer allows the self-adjuster to function.
