NOTE:
The straight stretch shank bolt should be replaced when performing repairs; it must be used only once.
As of May 1995 the bolts of the driven plate and two-mass flywheel (sheet steel two-mass flywheel) have been standardized. The torx bolt (3rd version) should be replaced when performing repairs.
Special tools
NOTE:
If no tightening angle torque wrench is available, the stretch shank bolts or straight stretch shank bolts can be torqued further to the specified angle in a single operation with a wrench socket and tommy bar. A flexi-rod torque wrench must not be used for tightening to tightening angles in order to avoid any angle errors. For design of two-mass flywheel see "Function of two-mass flywheel (03-4600) ".
