The clutch disc is the central connection element in the drivetrain. In combination with the clutch pressure plate, it separates and links engine and powertrain. Every LUK clutch disc features a lining resilience system that is optimized to the particular application and enables smooth torque build up when moving away and an ergonomically synchronized pedal force curve. Reducing the speed and torque fluctuations generated by the cylinder firing processes, the clutch disc also provide the damping function, in order to reduce noise and wearing on the transmission. Clutches come with torsion damper and without torsion dampening.With torsion damper is the most cost-effective and space-saving solution for overcoming torsion fluctuation problems in the drivetrain. The cone centering device developed by LUK corrects potential axle displacement between engine and transmission and guarantees a precise damping function, even at idle.Without torsion damper is used with the most effective torsion damper system currently offered by LUK, the dual mass flywheel. Engine and transmission tolerances, especially on transmission input shafts without pilot bearing, results in a displacement between crankshaft and the transmission. In conjunction with rigid clutch discs for the dual mass flywheel, this displacement can cause idling noises and increased profile wearing in some cases. One solution to this problem is the displacement correction clutch disc, which enables radial displacement of the hub and thereby prevents potential radial forces in idling and low load ranges.Dual mass flywheel/torsion dampers reduce idling noiseSound functioning of the dual mass flywheel is therefore guaranteed, even on displacement. The combination of dual mass flywheel and clutch disc with torsion damper is the best solution for particularly noise-critical applications.The five most common reasons for clutch problems are:¥ Clutch fails to disengage¥ Clutch slips¥ Clutch judders¥ Clutch makes a noise¥ Clutch pedal is heavy in operationSee the clutch kits we offer on our site, easy lookup by vehicle manufacture and model number.  Info is offered to help you in diagnosis of clutch problems on our website http://www.provenforce.com/clutch/clutch_cat.html.
