VALEO DDC

DMF TESTING The LuK testing tool 400 0080 10 (ECP Ref 400776250) allows you to perform the following tests on the DMF: ■ Measuring the freeplay angle ■ Measuring the rock These tests, alongside a visual inspection to check grease egress, thermal load, clutch condition, etc. allow for a reliable assessment of the DMF’s operational condition. What are the freeplay angle and rock?

The new Valeo smart OE transmission systems technology for outstanding responsiveness and comfort. The Valeo Dual Dry Clutch stands for outstanding performances embedded in OE technology. A smoothly continuous acceleration, with a minimum loss of torque means powerful driving sensations and electromechanically controlled gears change boosts driving efficiency.

The Valeo Dual Dry Clutch’s 7 gears actuators offers 15% faster gears change compared to previous generation of DDC from Hyundai-Kia, with a 6 gears transmission. Combined, these features make the Valeo Dual Dry Clutch one of the best available on the aftermarket, offering the comfort of an automatic transmission and the responsiveness of a manual transmission. CO2 emissions reduction is important to Valeo and has been at the centre of the development of the Dual Dry Clutch. As a result, Valeo DDC was designed to offer a continuous transmission of engine power, with minimum torque loss during gears change. Its gears disengagement operates without electrical power being controlled by the electromechanical actuator. Working together, these innovations enhance smoothness, lower vibrations and resistance, ultimately reducing fuel consumption and CO2 emissions. Valeo offer offers a simple manual calibration procedure for better efficiency in the workshop too. In addition, the offer comes with a complete technical support programme, including fitting instructions, live training, webinars, interactive presentations and videos from the Valeo Tech @ssist free online technical web platform.

The freeplay angle is the angle at which primary and secondary mass can be rotated against each other until load is exerted on the arc springs. The measuring points are both end stops in the left-hand and right-hand direction of rotation. The measured freeplay serves as a wear indicator. Caution: Some DMFs have a friction control disc that can be felt as a hard stop in one direction. In this case apply greater force to rotate the secondary mass a few more millimetres until spring resistance can be felt, and then allow it to return. This also rotates the friction control disc in the DMF. The term ‘rock’ describes the clearance between the two DMF masses which allows them to be tilted towards and away from each other. Your assessment of the DMF’s operational reliability should be based on the following criteria: ■ Grease leakage ■ Condition of the friction surface (e.g. signs of thermal load/thermal cracks) ■ Noise behaviour ■ Condition of the clutch ■ Loading condition of the vehicle (towing a trailer, driving school, taxi, etc.)

If in doubt, always replace the DMF along with the clutch.
