New Crankshaft Sealing Ring On Flywheel Side
Vehicle Type:
911 Carrera (997)/911 Carrera S (997)
Model Year:
As of 2005
Concerns:
New crankshaft sealing ring on flywheel side.
Situation:
Crankshaft sealing ring on flywheel side leaking.
Because of possible leaks at the crankshaft sealing ring, a new crankshaft sealing ring has been installed in the engines of the vehicles mentioned above
since May 17, 2005.
The new crankshaft sealing ring is made from a different material (PTFE). The modified sealing lip design is the same as that of the crankshaft sealing
ring used in Cayenne engines.
In the event of a complaint or when carrying out engine repair work that involves replacing the crankshaft sealing ring, the new crankshaft sealing ring
must always be fitted.

Note
^
The new crankshaft sealing ring (sports cars) can be identified not only by it's part No. but also by it's green assembly sleeve.

The crankshaft sealing ring with a white assembly sleeve is only designed for Cayenne engines and must not be installed in the engines of sports
cars.
