Among other things, the SACHS DMF testing tool for dual-mass flywheels checks the free travel of the torsional damper, the evenness of its spring force, the axial bearing conditions as well as the displacement travel of the radial bearing point.
Please note that this special tool for dual-mass flywheel tests and dual-mass flywheel diagnosis was designed specifically for DMFs by the SACHS product brand. Dual-mass flywheels by other brands require other DMF tools and can therefore not be checked using this one. The same applies for dual-mass flywheels with a transfer plate as well as those for dual clutch transmissions. These too cannot be checked with this tool due to their design.
