LS7 clutch in T56 problems
I posted this on LS1 tech as well but I thought you guys might have some insight as well...
I have a 1991 Camaro RS with a LS1/T56 swapped into it from a 2000 Camaro SS.
This past weekend I swapped in a LS7 clutch to replace my LS1 clutch since it had begun to chatter and was gross etc..
On the GTO forums, someone posted this
The parts I put in are these
LS7 clutch
LS7 pressure plate
LS2 flywheel
LS1 slave cylinder
Pilot bearing
Once the car is on and in neutral and sitting still, we cant get it into any gear... Its as if the clutch isnt disengaging fully... While driving, it is a huge pain to pull it out of gear with the clutch pedal pressed in...
Some people say that their clutch engages right at the floor with the LS7 clutch but it seems like the pedal is just not doing very much...
What can I do? Im assuming the problem is with the adjustment on the pressure plate... Do I just need to drop the tranny and readjust the pressure plate? I can barely drive my car the way it is now... When you shift, its necessary to rev match and force it into gear and when you need to stop and start moving again you need to turn the car off and put it into first and then start the car again to begin moving....
Please help. Thanks!

There is also a pre-install procedure that must be performed before installing these pressure plates. There is a self adjusting mechanism within the pressure plate itself that must be turned fully counter-clockwise.
To do this the pressure plate is put in a press (plate surface down), apply pressure to the fingers with the press just enough so that you can take two screwdrivers (or similar) and turn the adjusting disk CCW. The self-adjusting disk is recognized by three small springs just outside of the center hole, these must be compressed by turning the internal disc. While holding tension with the screwdrivers, release pressure being held on fingers. Then install pressure plate.
This is why you guys are getting engagement on the floor, and more than likely Lisa's problem as well. But, I'm just a dealer tech, so what do I know.
We listened to what he said and we adjusted the pressure plate.

Re: LS7 clutch in T56 problems
Sounds like the pilot is binding in the pilot bearing.

Re: LS7 clutch in T56 problems
This isnt whats happening...
The symptoms of that are EXACTLY the same as a non-releasing clutch: the engine stays part way hooked up to the transmission (those being the parts on either side of the pilot bearing). It's just the pilot doing the "dragging", instead of the clutch disc.
Sounds to me like the pilot is binding in the bearing.

You can smell the clutch burning when you have the clutch pressed in and you rev it
