When making repairs always renew the complete disk pack. The
replacement of individual disks is not permitted.
When reassembling smear all faces of the disks, pressure plates and
axles lightly with gearbox oil.
To check the basic locking torque, a flange with two bolts should be
mounted in a vice. The second flange with the connection piece
(996.450.322.90 ) should be fitted to the differential and rotated slowly
using a torque wrench.
A basic torque of between 90 Nm - 135 Nm should be achieved.
Wear limit < 60 Nm
The 911 GT3 Cup is equipped with a 5½" three-plate sinter metal clutch.
Attention: The clutch is specially designed for motorsport use. To
prevent excessive wear or overheating, the clutch should not be
slipped when driving (manoeuvring or during unloading and
loading).
