Default Clutch slave spring

Hi Lucky. The slave spring. I cannot get it off the make the cleanance measurements. I've always had a problem shifting from 1st the 2nd after to replaced the clutch and slave. My big isses now, according to the following measurements. I should have a gap between measurements A and B. Right now there both the same. I need to recheck my Slave measurement but I cannot take off the spring.

Check it out!

The follow is from Tick perfoemance.
How to determine if a shim is needed for your setup:
During each and every clutch install you perform on a newer GM vehicle, you must measure to see if a shim is necessary for proper installation. This is done by taking two simple measurements (see worksheet):
1)* Measurement "A" is the distance between the surface of the bellhousing that meets the transmission to the tip of the pressure plate fingers. To get an accurate measurement, the clutch must be torqued properly.
2)* Measurement "B" is the distance between the throwout bearing surface to the transmission surface that meets the bellhousing. To get an accurate measurement, the slave spring must be removed and the bearing must be fully seated at the bottom of it's travel; resting on the slave's base. (I cannot make this accurate measurement)
Once you've got your two measurements, make sure that measurement "B" is ~1/16“ (.0625) to 1/8“ (.125) LESS than measurement "A". If you come up with more than 1/8“ (.125), add an appropriately sized shim between the slave cylinder and the transmission in order to get the measurements where they need to be.
Your “A minus B” measurement should be 0.125 to 0.200 for adequate bearing travel and to allow for clutch wear. If there is no difference between the two measurements, or if "B" is greater than "A", there could be a problem with clutch engagement which could result in premature clutch slip and eventually a total failure. Contact your clutch manufacturer before proceeding with the install.


Thanks,
Steve

I don't see how you could remove the throw out bearing spring, without pulling the torque tube back.

I would think that you would have to push onto the t/out bearing, causing tension on the spring & turn to release off the lug.


It's just a suggestion.

Hope these pictures help.

Default Slave spring

Hi Bumble-z, yes the pics do help.
I was able to get my son to hep out. I re-checked my measurements however the spring is still installed. I would hate to have To take apart the slave sylender assembly and perhaps damaging the salve in the process. The lugs is whats holding the assembly together.
My orginal issue was the cutch not fully dis-engaging. The same A and B measurements back up the condition. This is why i get gear grind between 1st and 2nd gear. According to Tick, if you jack up the rear, run the engine with the can in gear and in 1st, the wheels should not even move an inch. I have that condition. Sitting at a stop light and putting the car into 1st, I can feel the car move. recendly I been experencing a major issue in tyhe morning with the clutch fluid be cold the pressure dynamics are less. I cannot to second. I got to start out in second and ease into third. So my clutch is wearing out.

So now I stuck...... With not existing shims, the measurements are the same. Buy a new clutch and hope ther problem is the pressure plate, or reassemble the entire car and send it to a Cunningham motorsports herer in Murrieta Ca.
I'm not sure whjat to do at this point.

Default Clutch

I did purchase a used clutch from a forum member as a backup. I'm thinking of pulling my existing clutch and replacing it. The used clutch is a LS7 assembly. It could be the pressure plate is the problem. Any suggestions?

hornet 7,
Why in the world would you even contemplate installing used
parts?

I have never under stood with all the work that is involved in a complete clutch change out with these c5's, why one would buy used replacement parts.

I've seen many selling & others buying used slaves & the likes here on the forum.

Evidently you have allot time on your hands.
If that is the case, I'd be calling Joey at Tick performance, bright & early in the am.
Run all your questions by the pro's there.
That's what they do, day in & day out.

If you do not have the shim kit in your possession, I'd be ordering their three piece shim kit.
Good luck.

Default Clutch

In purchasing the used clutch as a backup to compare what I have on the vehicle. I don't know if I'm going the swap it at this time. The clutch that I have is fairly new but I don't know if this issue has caused excessive damaged. I'm going to wait until I contact Joey or Cunningham tomorrow and discuss what could be the issue.

Thanks for your help.
