NEW LUK CLUTCH KIT!
A glance at the benefits of the Luk dual mass flywheel
Top driving comfort
Absorbs vibrations
Prevents noise
Enables comfortable, low-revs driving
Saves fuel
Relieves crankshaft and gearbox
This all makes the LuK dual mass flywheel the ideal solution.
With one drawback: the higher the mass reactance of the vibrating masses, the more excessive the resonance increase and associated torque peaks. With the dual mass flywheel, this would be easily perceived when starting and stopping the engine; much more easily than with a conventional clutch system. Additionally: the smaller flymass of the engine has less of a stabilising effect on the speed fluctuation of the engine.
Thanks to decades of experience in clutch building, the LuK specialists were able to find an excellent solution to this problem. An additional damping device effectively prevents resonance overload. In normal operation, however, this additional damping device has no function and the torsional vibrations of the engine are filtered out by spring dampers.
Friction and spring rate – the correct ratio is important.
For optimal vibration isolation and soft resonance passage when starting and stopping the engine, the ratio between friction and spring rate must be optimal. The length of the springs is a key factor: The softer a spring, the more efficiently vibrations are isolated. The extra-long springs of the latest generation of dual mass flywheels significantly reduce the spring rate compared to a first generation dual mass flywheel. In routine driving operations, excessive resonance increases are kept almost completely away from the gearbox.
Unquestionably, the highest-quality line of clutch replacement sets in the market. Why? It's all about designing and manufacturing clutch system technology for original-equipment vehicle manufacturers throughout the world. In the domestic market, LuK is North America's largest original-equipment clutch supplier from its engineering, development and manufacturing facility in Wooster, Ohio.
Specifications:
-12 1/4" outside diameter
-1 1/4" disc spline size
-10 tooth
***Performance Tested***
LuK clutches and discs undergo rigorous testing at each step in the production process, from component parts through final assembly testing.
Clutches must pass tests for clamp load, release load, pressure plate lift and variation, finger height and wear capacity.
Discs undergo testing for cushion deflection, torque capacity, spring rate, facing parallelism and compressed thickness.
***NOTE: Replace clutch master and slave cylinder, these vehicles were prone to a defective hydraulic release system. To eliminate leaks that may cause this condition install upgraded master and slave cylinder. These components must be installed together. A new tube kit, Ford part #F5TZ-7A512-A and pedal pivot shaft lever, Ford part #E7T2-7A554-A, must be used with the upgraded parts. For additional info refer to Ford bulletin #95-4-9.
