Is the clutch disc the same as the flywheel?

Clutch The clutch assembly consists of the clutch arm or actuator, the clutch disc and the release bearing. The flywheel is the interface between the clutch mechanism and the transmission. The clutch disc can become worn; this is a normal consequence of driving, and will occur at intervals of 60,000-100,000 miles, depending on driving conditions.

How to replace and remove new clutch kit and flywheel on?

Install the new flywheel and hand thread the bolts. Tighten them in a diagonal pattern to 44 ft-lb. Double check them. Then tighten them all in a diagonal pattern another 1/4 turn. They are single use stretch bolts with threadlocker and should not be reused. Very lightly grease the splines of the clutch. Less is better.

What happens to the clutch when the flywheel is worn?

When severely worn, the clutch will “slip,” losing traction against the flywheel; this will result in the engine racing without transmitting power to the transmission, particularly under load or hard acceleration. The clutch release bearing can also become worn.

Can you mix Sachs clutch with Luk flywheel?

You cannot mix Luk and Sachs clutch/flywheel/pressure plate kits because they won’t fit. DMF are also known to wear the dampening elements and rattle. I chose to replace the DMF with a new “early” Luk DMF which is supposed to be known for good life.
