Removing and fitting the crankshaft seal – crankshaft side

3.8.7.1.

Special tools

Porsche Motorsport recommends use of the following special tools to
remove and fit the flywheel side crankshaft seal:

Pressure pad:

000.721.912.60

Seal extractor jig:

000.721.971.90

3.8.7.2.

Removal

Drill two holes (Ø 2,5 mm), 180° opposed from one another, into the

metal ring of the crankshaft seal. Never lever out the seal!

Screw the threaded end of a commercially available slide-hammer

alternatively into the holes and extract the metal ring evenly.
