Ralf Kuhlmey, Technical Trainer at Schaeffler in the Automotive Aftermarket, conducts visual inspections of several LuK Dual Mass Flywheels (DMF). He demonstrates different damage patterns that can occur with a DMF – like heavy grease leakage, blue coloration, a bearing rock that's not within the tolerance limit, or worn out bearings.
