Good Evening: please any advise, here's the problem

when i push the clutch pedal i can't change gears, this happend suddenly, last monday, so i came home and check the master and slave cylinder and found that the slave don't move too much, i purge the line, but the slave don't move all the way out so i put a 1" more round metal to move the clutch, at this point i can't put the car on shift when it's on, so i turn off the car, put 1 gear and start again, of course the car move and start in 1 gear but i push the pedal and change to neutral and then i put all the gears like normal (car still on)

so next day i replace both cylinder, just in case, i purge again and now i can shift gears, but in the morning when the car are cold (tranny too) it's something dificult to put in gear.

another thing, sometimes when i stop the car and push the pedal, i feel that the clutch don't des-engage so i have to take out the gear, push all the way out the pedal, i remember that before this issue i just have to push a little bit the pedal (like 2 " not all) and then change gears easily with no noise.

this is my second clutch repset (LUK) since 2007, but when the mecanics put the last one i feel the cluth too much soft, but the car runs great, but i've notice that the FORK that the slave cylinder move it's very loose, the slave cylinder are like 3" out(i think the whole pivot are 3,5"), when i bought the car the slave cylinder move like 1 inch out and the fork are not loose.

what can be wrong the whole clutch set or just the fork and bearing? bvecause right know both cylinder move all the way out with good pressure and no air inside the line.

please urgent any advise, best regards

check this pics

normal way of the slave cylinder



but is this normal?, you can push the slave cylinder with the finger easyly, qhen you push teh pedal it's goes out and stay there but the fork still a little bit loose, is this normal this thing?

i forgot what the procedure for doing this, but there is a rod on the clutch pedal for the some adjustment for proper clutch pedals to floor distance. This may help you bleed the system better. I will see if I can find my manual and post it up

thank you escortwhisperer, i already adjust the clutch pedal, put like the manual says.

today i purge again the system without any bubbles, the DOT3 are very clear.

i think if you have problems with the release system your are going to broke the clutch and have to replace again

Throw-out bearing is toast.
I agree, same thing just happened in my Corolla AE86. TO Bearing exploded, and when I pushed int he clutch pedal, the slave over-extended and pipped the piston out of it's bore.

right now i take out the tranny and guess??

bad Pilot Bearing/Bushing, i have to take it out

i check the clutch and the disc and it´s like the new one, the trow-out bearing are OK.

i´m going to clean the bell very well, change the pilot Bearing and the crankshaft seal because it have some drops leak.

my tranny shaft don´t have any play so my question is why this pilot bearing is damage, what can cause this damage??

best regards

Probably a lack of lubrication. I had the same problem with the pilot bearing on my car last summer.

yes, the problem was the pilot bearing, yesterday we put the tranny again, we only replace the pilot bearing and that fix the whole problem.

now you can change the gears very easy, softly and without any noise.

thank people, i really apreciate your help

So what was the issue with the pilot bearing, was it seized or something? I've never seen a pilot bearing cause issues like that.

the pilot bearing was stuck, it barely made marks int the tranny shaft.

after we saw the pilot bearing damage i called to LUK service here in mexico and they told me that the pilot bearing if very important to center de disc.

if you have this issue the disc can´t engage between flywheel and clutch and it can slip, also you can´t change gear because the disc still engage because the des-alignment (partial engage).
