god damned clutch!!!

[1fast97gsx]

I have tried everything to do to get this clutch adjusted right. Right now I got it so it felt awesome, but if I park the car for a while and then get back in the engagement point moves towards the floor and the pedal is very soft the first 40% of the pedal travel. Once I drive it for about 10 -15 minutes then the engagement point moves back out slowly and the clutch stiffens up. What the heck would cause this?!!? I have tried everything. Would the restrictor removal inside the slave cylinder cause this problem? Other than that I'm clueless.

With my old car the clutch would feel wierd and would cause me grind the gears, I removed the restrictor and it solved any problem that I was having.

I'm not grinding any gears though I'm just having my engagement point move back down if I let the car sit for a while and the pedal feels soft / mushy. I'm not leaking any fluid either.

Don't mean to scare you but isn't this one of the symtoms of CW?

Man, i donl't think it's crankwalk You might want to check your slave cylinder for adjustment. My gst is doing somehting similar, except it's having a problem with the clutch catching too. I took it to a garage and the slave cylinder just needed to be adjusted by adding a shim to it.
Might want to look into it. just my .02

FASTGSX I to had alot of problems gettting my clutch to disengauge as well after I put the new motor in. I pulled the trans it out at least 4 times trying everything as well. I would replace both master and slave cylinders if they have more than 60k on them. Also replace the copper crush washers at the slave cylinder. I ended up putting a .060 10mm washer under the pivit ball and helped out alot and get alot more adjustment out of the master cylinder rod. Make sure your flywheel is steped properly and should be .609 - .611 for best clutch performance and life. It sounds to me like your master cylinder may be bad. PM me with your cell if you are still having problems.
BTW its not crankwalk Hes got a fresh motor.

Read up on the Pedal Pump Up.

yea I read that section before on the pedal pump up on RRE site. I will try and mess with it again though just to be sure. I have tried 2 slave cylinders now but I didn't replace the washers so maybe it's something as silly as that. If I figure out my problem I'll let you all know.

btw ... this is a built 6 bolt, it's not crankwalk

well I'm still having problems with it ... I replaced the slave and it helped but it still gets a little soft if I let it sit in the cold or overnight. Then after a few minutes of driving it pumps up and then feels just like it should. Maybe there's more air in the lines? The upper pedal stop is ALL THE WAY out so I'm not sure what else to do. The master cylinder rod is about 1/2 way screwed in. Maybe back that out some more ? ( so the pedal moves away from the firewall )

Also .. can someone describe what is meant by "freeplay" at the top of the pedal? My pedal isn't soft or anything right at the top once it stiffens up but the clutch doesn't disengage until about an inch or 2 of the pedal being pushed in. Is it supposed to literally be loose at the top of travel or is freeplay just meaning that it would disengage it?

Replace your factory rubber clutch line with a braided one from AMS. You may have some seapage coming out of the factory one causing your loosing pressure situation. Just throwing ideas out there for you to look at.

Yea also back off your rod some. You should have no free play in the petal. How far off the floor is the clutch engauging?? It should start engauging 1- 1.5 inches off the floor.

Problem with that is he'll loose more pressure but if he doesn't, he will soon blow out the slave cylnder. I agree with the ss line idea, when it get old it will expand causing you to loose pressure. Good luck.

he has allready done this unfortunetly. Cedric aside from replacing the rest of the line and eliminating the accumilator I have no idea what else you can do.

eric - how much would you guys charge to mess with it and get it adjusted right?

Just to follow up there is no air in the lines, I have a brand new slave, ams clutch line, removed the acumulator and it still feels soft if I let it sit outside overnight or in the cold it gets soft again, but it still engages / disengages good enough for the tranny not to grind. Could it be that it's just ty fluid and thats my only problem? I'm using dot 3 stuff I got at a local store. Thanks.

Well today I got the clutch adjusted so it fealt great and wasn't preloading at all. When I parked the car and let it sit for a few hours and get back in the engagement point moved all the way down to the floor and the pedal got really soft again. There's no visible fluid leaking, but could the master still be bad?
