  • Only use the original packaging in which the new crankshaft seal was supplied (new cankshaft sealing ring p/n 997.101212.00).
  • To avoid damaging the sealing lip, do not secure the parts tag to the crankshaft seal using fastening wire, instead place it with the original packaging or attach it to the outside of the packaging (Figure 1).

The identifying feature of the new crankshaft seal is the 8 rectangular cutouts on the outer side  of the sealing ring (Figure 2).

The new seal covers Porsche Boxter M96 engines with casting numbers 25 615 08519 (2.7L) and 26 625 07322 (3.2L).

Some or all of the technical information was provided by the Automotive Parts Remanufacturers Association (APRA). For more information on technical bulletins available through APRA call 703-968-2772 or visit www.AutoBulletins.com.
