Clutch Mechanical

The transmission must be removed
from the engine to access the clutch
mechanical components. It is
recommended that the clutch disc,
pressure plate and release bearing be
replaced during a clutch overhaul. Be
sure to check the bottom of the
bellhousing for oil. If engine oil is
found, check for a faulty rear
crankshaft oil seal.
Due to the construction of the self
adjusting clutch (SAC) disc special
tools must be used when removing the
SAC style clutch. The pressure plate of
the SAC clutch uses a wedge ring
which rotates against the diaphragm
springs to accommodate for clutch disc
wear. The wedge ring adjusts by
means of spring tension, so special
tools must be used to apply and relieve
spring tension as the clutch pressure
plate is removed and installed. For
special tools needed for clutch
replacement procedures refer to the
