Installing Sealing Ring For Intermediate Shaft

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.
  1. Check crankcase bore for sharp edges. Break off (deburr) any sharp edges on the crankcase bore (intermediate shaft flange) with polishing cloth or an oilstone.
  2. Grease the new sealing ring slightly with Optimoly MP3 (available from Porsche Parts Service) and insert in the groove of the intermediate shaft flange.
    NOTE:
    • The sealing ring must not be twisted and must not be pulled over sharp edges of the flange.
  3. Position intermediate shaft flange on the bore and affix with new micro-encapsulated hexagon-head bolts.
    NOTE:
    • Do not exert any pressure on the threaded pin when pushing in the intermediate shaft flange, as the threaded pin might otherwise be pressed inward into the intermediate shaft.
    • As soon as the threaded pin projects at the intermediate shaft flange, screw the new lock nut into position.
  4. Position and align special tool retaining device 9642. See Fig 1. Centre intermediate shaft and intermediate shaft flange by turning the crankshaft to and fro a little (max. 2° to 3°, remove dowel pin from the belt pulley first).

    NOTE:
    • It must be possible to insert the intermediate shaft flange almost completely into the intermediate shaft bore by hand.
  5. Tighten the three micro-encapsulated M6 x 20 hexagon-head bolts evenly. See Fig 2.

    Tightening torque 10 Nm (7.5 ft.lb) 

  6. Tighten lock nut M8 x 1 with the socket wrench 9110. At the same time, have a second person counter with a suitable screwdriver in the slotted threaded pin. See Fig 3.

    Tightening torque 11 Nm (8 ft.lb) 

  7. Fit new sealing rings to both chain tensioners, screw in and tighten.

    Tightening torque 80 Nm (59 ft.lb) 

  8. Fill in engine oil. Refer to ENGINE MAINTENANCE: OIL CHANGE WITH FILTER CHANGE or CHANGING THE ENGINE OIL AND OIL FILTER -- AS 2003 . .
    NOTE:
    • Replace screws for the double-mass flywheel and drive plate for the torque converter.
  9. Fit double-mass flywheel or drive plate for the torque converter.
    NOTE:
    • In order to avoid deforming the thrust plate housing, always tighten the pan-head screws on the clutch pressure plate in several stages and in diametrically opposite sequence.
  10. Fit the clutch pressure plate with drive plate.
  11. Install manual transmission or Tiptronic transmission.
