Clutch won't adjust, input needed.

[Denji]

i seem to be unable to change the height in my clutch pedal where it engages. I can increase or decrease freeplay and pedal height only, but i cant literally move the engagement point to 1" or so from the ground unless i move the pedal down near the ground. Heres the only real effect i can have.

I can set it up like this

_top
-freeplay
-freeplay
-
-engagement point
-
-
-
-
-
-
-
_bottom

or I can do this to the pedal.

_top
-freeplay
-freeplay
-
-engagement point
-
-
-
_bottom

This is what i want.

_bottom

Are you just adjusting the pedal height/ freeplay switch? That won't really change the engagement point. Make sure you're adjusting the cylinder rod.

I have been using both. It appears to me that the cylinder rod only creates freeplay or lessens freeplay, while the other where the switch is at adjusts the height, i dont understand how i used to move the engagement point, is there something wrong with my master cylinder?

40k on your car? thats crazy mine has 150,000

You are asking for what can be done to a mechanical clutch. Hydraulic clutches simply does not work that way and can not be manually adjusted the way you want it to be due to it being self-adjusting.

You can only do two things to lower the disengagement point
(1)lower the resting pedal height so the disengagement point drops along with it.(your 2nd description)
(2)adjust the rod so that you have maximum pedal freeplay, but the effect is minimal to none if your clutch was adjusted properly in the first place.(your 3rd description)

Hah yeah 40k miles. It was hard seeing it hit 40k miles just a few weeks ago knowing I bought it with 31k last year. Haha.
Anyway, I would try adjusting the top freeplay pedal to where it has the correct amount of freeplay and lines up your clutch pedal with the brake pedal.
After that's right, THEN I would adjust your cyl. rod. I would turn it 1/2 at a time, then test. 1/2 turn again, then test. Those small turns actually make a big difference. You'll then find your happy medium.

I understand what your saying, it seems as if i was able to do it before but perhaps it just seemed that way because it was on my old master cylinder and it probably was leaking ( a couple of years ago). Okay, I appreciate it both of you for your responses, I'll check back in shortly to let you know what I did. I think the pedal assembly is kinda old because the spring just doesnt seem very strong once there is no hydraulics pushing the clutch back up.

What do you mean no hydraulics pushing the clutch back up? The clutch sticks to the floor, or when it comes up, you have to lift it up even more with i.e. your hand because it doesn't come all the way up?

I was trying to specify that the freeplay area where there should be little resistance, actually has very little on my car, to an almost annoying point. If the spring were stronger, i wouldnt mind putting more freeplay to make the engagement point lower in the pedal travel. I guess it may just be how its supposed to be and maybe i have too much freeplay. It always returns on its own to its original maximum height position.
