LuK DMF testing tool

Using the LuK DMF testing tool allows you to determine possible damage to the DMF by measuring the rotational freeplay angle and the bearing rock. Ralf Kuhlmey, Technical Trainer at Schaeffler Automotive Aftermarket, goes through assembling the tool step-by-step, and explains what you need to pay attention to when conducting the test. Along with the results of a visual inspection, this allows garages to judge whether the DMF needs to be replaced.
