Need Help!! Clutch Adjustment
I put an LS6 in my FRC and just got it going again. My problem is the clutch is barely disengaged when the peddle is on the floor. When I say barely I can feel the car wants to move so it's still partially engaged. What did I do wrong? and how do I fix it without taking the whole car apart again?
By the way, the new motor is fantastic.
TIA,
Mick

Sounds to me like the slave is full of air.. Bleed it good.. That pedal should feel hard as SOON as it starts to move and the Master Cylinder pushes fluid..
If it's soft then it's full of air..

I bleed the clutch this morning, the fluid was a nasty green color. I bleed it until I had clear new fluid coming out. The engagement/disengagement point is still on the floor. Is there any way to move where the cluch engages?

If you pump the clutch pedal a bunch of times... does it raise the disengage point? If it does.. that means you still have air in the line..

I'm having similar problems, although the clutch will fully disengage, it starts grabbing an inch off of the floor. I have about 3" - 4" of free play at the top of the pedal before it starts to get stiff.

You can not adjust the release point of a hydraulic clutch, When you move the clutch pedal, it is only going to put so much fluid into the slave and thus only move it so far. I think Mcloid makes an adjustable master cylinder but if your slave is already at full travel, that is not going to help you either. I would call Mcloid and talk to someone there. I can not think of anything you might have screwed up on the clutch install as there are no spacers or anything. The slave bolts directly to the torque tube and the clutch to the engine. That would just leave the throwout bearing. I wonder if the LS6 has a different thickness throwout bearing than the one you had before?????
Good luck

Tha's a good question. Does anyone know if there's a difference between the LS6 and LS1 throwout bearing. I'm guessing not since I read of people changing over to the LS6 clutch. Anyone?

For those trying to help me; I have bleed the clutch until I had put a quart of new fluid through it. I feels good in the driveway but after 3-4stop signs it starts to do the same thing, the disengagement is near the floor. By the time I get back home I have to kill it to get it in reverse. Could it be the master cylinder? Is the slave separate from the throwout bearing? What else am I missing?

Since it works for a little while my guess would be that the master cylinder is leaking internally thus not pushing as much fluid to the slave after a while, that is assuming that you do not see any leaks at the slave. It is the same thing as when you push on a brake pedal and it gradually goes to the floor. The fluid is just leaking around the seals in the master cylinder and going back into the reservoir.
Just my thought.

I agree with this diagnosis. I have a Ram Adjustable MC and it's doing the same thing. I don't reccomend this product to solve it since it's just the OEM piece reworked. In addition I haven't gotten return calls/emails from Ram about helping me to fix this problem.

i just installed a new ls6 clutch in my '99 C5, with new slave. Everything was fine the first couple of days it was fine. I then began to notice that the engagement point was getting closer and closer to the floor, until yesterday that I went to move it and it wouldn't go into any gear.
I bleed the slave of most of its old fluid. I don't see any leaks around the slave, and the reservoir is full. I did notice in front of the oil pan some fluid that wasn't trhere before. Before this clutch change the clutch hadn't been changed in over 100k miles. fluid was very dirty. Could this be a clogged reservoir? Or is something else leaking.
