Hey guys, i was wondering if anyone knew the proper way to adjust the clutch pedal on our cars? I notice that theres a lot of free play with the clutch pedal before it becomes nice and tight when i press it down. I bleed the clutch fluid thinking it may fix it, but it didnt fix the free play, but did make it tighter. I think i read somewhere that the clutch pedal can be adjusted by loosening a lock nut and twisting the push rod more towards the pedal? Is this the way to fix the free play? And how exactly do you do it? Thanks!

ok under the dash at the pedal box there is 2 adjustments, one is the adjustment on the pushrod that goes to the master cylinder, the other is the stop adjustment (the stop is also a sensor on some cars) what you do is undo the lock nut on the push rod, then pill the split pin off the pin that goes throuht the pushrod and the cluch pedal, then give it a few turns out, then reinstall the pin and see if thats better, if it is put the split pin back in, do up the lock nut and your done.

Make sure that the pushrod is not tight against the pedal when you reinstall, leave a tiny ammount of free play.

if you need more travel undo the stop and wind that backards (as in so it winds toward the drivers seat) lock it up, then adjust the pushrod again.

ok so i loosen the push rod lock nut, remove the pin that goes through the pedal, which will remove the assembly off the pedal, then turn the push rod? Which way am i spinning the push rod to tighten the freeplay? Do i want to spin it away from the pedal, or towards the pedal?

you want to turn it toward the pedal, so the u shaped piece comes closer to the seat.

cant i just loosen the lock nut, and twist the shaft towards the pedal, then tighten the lock nut? do i have to remove the u shaped piece? Will the shaft not turn unless i remove the u shaped piece and actually twist that?

so in order to lessen the freeplay, im twisting the shaft towards the firewall, so theres less of the threaded part of the shaft inside the u shaped piece?

by adjusting the push rod, can you actually change the clutch engagement point? I feel that the clutch engages too soon. When i start to let the clutch out the clutch engages when the pedal is like 3 inches off the floor. Can i adjust it and make it so the clutch engages higher?

if you want the clutch to engage further from the floor the you need to do as i have sugested. On all the cars ive done clutch adjustment on you need to turn the "U" peice, chillax bro its a piece of piss job, just get your noggen under the dash with a torch and a spanner (prob 12mm from memory for the lock nut)
pair of pliers might be handy for the split pin.

get out there and have a dip son tongue.gif

damn, this sounds like exactly what i need to do to get my new os geiken twin plate clutch flywheel combo to start engaging off the floor

currently clutch engage point is the floor, i want it higher so ill do as mentioned and move the u piece closer to the seat (thus increasing the stroke of the pushrod)...is this correct? Thanks a million for this guys, feels like im driving a VW

I've done this a billion times and after playing around with different adjustments, i can tell you that the best way to do it is to use a ruler. Set the pedal height to 5 1/2 inches with a 1/2inch of free play. That will give you the best results.

Dont remove the U shaped piece. You dont have to do it, and it would probably make the job more trouble than its worth. Just loosen the nut and twist the rod to set the pedal height. Then use the round sensor thing at the top of the pedal to change the free play.
