Flywheel step is the step height of the outer shelf that the clutch pressure plate bolts to. It is the difference between the friction surface and the upper step shown here in the pic.
What’s the step height on a flywheel clutch?
If you were to machine only the friction surface of the flywheel, the clutch wouldn’t grab and hold as well. The step height is critical to proper clutch operation.

What is the function of the flywheel in a car?
The flywheel is the interface between the clutch mechanism and the transmission. It is a large metal disc, with a series of teeth around its outer edge; it resembles a large gear. The purpose of the teeth is to allow the starter to engage it and thus, turn the engine over.
What happens if the clutch and flywheel fail?
On a manual transmission vehicle, the clutch and flywheel are the two main components responsible for transmitting power from the engine to the transmission. If either one fails, the car will not be driveable.
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.
What are the signs of a bad flywheel?
Common Signs of Bad Flywheel Weird Burning Odor. I noticed my car before having such a weird burning odor in its interior. Gear Slippage.

Why do you need a flywheel in a manual car?
Cars with automatic transmissions instead use a flexplate that also connects the transmission to the engine. The flywheel ensures that the gears of a manual vehicle are functioning properly as the driver is using the clutch. It also keeps the vehicle from vibrating so much as well.
The flywheel can also suffer from broken and/or worn teeth. This can cause the starter to fail to engage properly. When you notice clutch “slippage,” it is usually because the clutch disc is worn. Other mechanical problems with the clutch can be caused by a failure of the release bearing.

Can a bad flywheel cause a clutch to not release?
As you may know, the spring mechanism is what normally reduces the vibrations that are generated from the clutch being used. This is only more proof that you have a bad flywheel and it needs to be replaced. This is the opposite of a clutch slipping. Instead of the clutch not engaging, the clutch simply won’t completely release.
