Clutch install gone Bad
 

Removed my triple disk clutch to go to Z1 JWT https://www.z1motorsports.com/clutch...hr-p-3388.html

Put the trans back in and after bleeding the clutch it will not dis-engage. I can look in the hole were the lines go through the the CSC I have .4 inch movement then the clutch is pushed.

I bough a bore inspection tool so I can look inside and see what is up.

Any ideas? I will put the car back to the stock unit tomorrow.

Z1 seems to think I is still a bleed problem.

I am using the duel mass flywheel with the JWT unit, could that be the problem?

Trans spins free in neutral and will not turn when placed in gear with the clutch depress.

I did not change the pilot bushing,

I am using the Z Speed CSC ZSpeed Performance Replacment HD Clutch CSC Heavy Duty Slave Cylinder Kit


Again, any help, Please

Do you have your clutch plate installed right. If you put it in backwards. The pressure plate will not release.

It is in correct, I need 7.5mm of travel on the CSC and I am only getting 7mm. I just put in a new master and slave. Still will not work. I have bleed the CMC at the line connection and below at at the slave. I have full travel on the master.

Z speed and Z1 were sure it would work with new hydro parts. NOT

If the JWT requires more force to operate than the 3-disk, you may have exceeded what the system will handle and are bypassing fluid at the master.

Or the JWT requires more travel.

Just guesses. Hope it's an easy fix.

If the pilot bushing is worn it would cause more clutch engagement issues when the engine is running. If the bushing got damaged during removal of the trans or when it was installed it will cause your problem. If the trans was removed without any weight put on that bushing (i.e. it didn't hang at all due to improper removal equipment, or the trans was not forced at all into position during install) then the bushing should be okay. The pilot bushing must always be replaced because its only protection is a small amount of grease that can never be replaced during its life (plus it's really cheap).
Next, if the wrong grease was used or too much, that could cause the trans output shaft to spin when the turning flywheel with clutch depressed. You can check this by turning flywheel with clutch depressed and holding output shaft of trans. I would change out bushing, use correct grease and correct amount and ensure proper install procedure of trans so as to not cause damage of bushing during install. If you can stop it then it could be bushing or other clutch parts not mating properly or working together. If you cannot hold the output shaft from spinning I would suspect incorrect amount of travel for the csc or a worn csc shaft (tube that csc slides on) which should be replaced when doing clutch. Hope that helps a bit.

OK, the clutch will not release, I test my install by having someone (my Son) depress the clutch after we bleed it before we start the car. It will not release clean. I can put a pry bar at the aft U-joint and make it spin with high force (200-250 pound feet) to make it slip.

I will not slip at all without the clutch depress.

I did not change the pilot bearing, It looks good, but I can.

Last week, with the clutch assy on a press, it releases fine with 7.5mm of press movement, the CSC-CMC only give me 7mm. not enough for a clean release.

Could the duel mass flywheel be damaged?

I am about to spring for the Z1 CSC system.

CMC and CSC were just changed yesterday, CSC is the Z-speed part.

Thanks to all. Keep thinking, I need the help!

Good news is I can remove and install faster than changing a tire!!!

Do you happen to have the rjm clutch pedal? If you do, You may have forgot to set it back to stock setting before the bleed. I did this and wasn't getting full travel in the clutch. Set the pedal back to stock and bled again, got the tiniest little bubble out, then it worked for me.

Just a thought

RJM is set to full travel.

I am still running the duel mass flywheel, anyone having problems with that and the z-speed CSC?

Z1 might be right. From my experience ZSPEED CSC is a bitch to bleed. I'd deff bleed it couple more times before removing anything again. Also did you bench bleed new master cylinder before installing it?

Look under the boot and see if there's an adjustment for the throw. There might be a threaded rod with a jam nut hiding under there.

Looks like there may be some spacers that go under the plate that holds the arm. Did you put those in?

He has our HD CSC, not the CMAK, The HD CSC has plenty of movement, so long as the RJM pedal adjustment and master adjustment is correct, to release the clutch unless something is wrong with the JWT clutch itself, We have been conversing on the phone with him to figure out what the issue actually is.

It is actually very very simple to bleed, The only reason it would be hard to bleed is if the master cylinder is weak or adjusted improperly.

Looks like Joe is on top of things.:tup:

yeah I've always heard it recommended when you change the CSC you should change the MC simultaneously.

OK today I received a Z1 clutch flywheel and pressure plate, took the day ff work to install it and it still will not release. So at the direction of experts I started the car and shifted in gear and applied the brakes. Motor ran slower but did slip. tried again and did not work and we had a smell. Checked and now when you depress the clutch it sprays fluid. Something is not tight. So I start to pull the trans again and it's stuck. All the bolts are out. Now the clutch will not release and the trans is stuck to the motor. Clutch fluid was black when I drained the slave cylinder. Anyone have a way to pull the trans? I am thinking a motorcycle tie down strap from the trans to the rear of the frame...

If I can't get it apart it will have to go to my local shop. HELP Please!
