Clutch
Installing the non-SAC clutch (1 997 5281 model) requires the
use of only a flywheel lock and traditional clutch disc align-
ment tool.
Installing the self-adjusting clutch (SAC) requires several
special tools for aligning and assembling the clutch, as well as
locking the flywheel in place. In addition, the procedure for re-
installing a previously used SAC differs from the procedure
for installing
a new SAC. Be sure to read the SAC installation
procedure through before starting the job.
The pressure plate of the SAC uses a spring-loaded wedge
rino to cornoensate for clutch disc wear. The wedge ring
ad-
;u$s by means of spr'ng tenson, so specal toolsh~st be
used to
appy and relieve spring tension as the c utch pres-
sure plate is installed.

Clutch, installing (new SAC components)
V-8 models and 1998 and later 6 cylinder models are
equipped with the self-adjusting clutch (SAC) pressure plate.
The SAC pressure plate, when new, comes from the factory
with a lock plate at the center which maintains spring tension
on the self-adjusting springs. This
loclting ring must not be re-
moved until the pressure plate is securely installed on tlie fly-
wheel with the clutch disk in place.
CAUTION-
Avoidcontaminating clutch friction surfaces with oilorgrease.
Do not touch these surfaces.
