Thanks Loren!  I did a recent 997.1 GT3 RMS replacement using this value (DMF).  It is all back together and running fine. Then I happened to look at the factory manual for the same procedure and below is how that read.  Am I looking at an outdated workshop manual?  


Installing double-mass flywheel
Before re-installation, clean the friction surface of the flywheel with a clean lint-free cloth that has been
soaked in solvent naphtha or acetone.
1. Position double-mass flywheel on the crankshaft's dowel pin and press on to the crankshaft flange. Insert
all fastening screws (8).
2. Align toothed segment 9538/1 and tighten fastening screw
3. Screw in and tighten fastening screws in diagonally opposite sequence. Initial tightening: 19 ftlb. ;
Final tightening - torque angle: 120 °

4. Remove toothed segment.
