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.
Once you've got your two measurements, make sure that measurement "B" is
~3/16" to 1/8" LESS than measurement "A". If you come up with more than
1/8", 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.
