For vehicles with V6 2.7 L-Biturbo engine, a SAC-clutch plate (self
adjusting clutch plate) is installed, on which an adjustment ring must
be reset except during replacement Page 30
-42
.
Replace clutch plates and pressure plates with damaged or loose
rivets. Select the correct clutch plate and pressure plate according to engine
code: Clean input shaft splines and (in the case of used clutch plates) the
hub splines. Remove corrosion and apply only a very thin coating of
grease G 000 100 to the splines. Then move clutch plate to and fro on
input shaft until hub moves freely on shaft. Excess grease must be
removed. Pressure plates have an anti-corrosion coating and are greased. Only
the contact surface may be cleaned, otherwise the service life of the
clutch will be considerably reduced. If the clutch has burned out, thoroughly clean the bellhousing, flywheel
and parts of the engine facing the transmission to reduce the smell of
burned linings.
