Things to Know about Dual Mass Flywheel
2
A dual mass flywheel is a type of flywheel
designed to absorb the shock of a clutch being
released.
3
The dual mass flywheel is part of a standard
transmission clutch assembly, which cushion the
shocks associated with releasing a clutch.
4
It not only helps with the feel of disengaging
the clutch, but also helps protect other parts
from the damaging shocks.
5
How does it work?
6
It is basically a two-piece flywheel as opposed
to the more common flywheel made from one solid
piece of iron.
7
One of the two main pieces called a primary
flywheel, bolts solidly to the rear of the
engine's crankshaft.
8
While the secondary flywheel is attached to the
primary section in a way that lets it rotate
slightly against heavy springs when the clutch is
released.
9
Symptoms of a damaged dual mass flywheel
10
A dual mass flywheel noise is commonly caused by
a damaged internal spring, while other noises can
come from internal parts in the cushion assembly.
11
If you experience a chatter when releasing the
clutch, it usually means the clutch pressure
plate or the flywheel is damaged.
12
Common problems associated with dual mass
flywheel
13
A common dual mass flywheel problem is damaged
internal cushion springs as the internal spring
assembly is the weakest point.
14
A big problem with dual mass flywheel is that
they cannot be resurfaced and if the clutch disc
mating surface has hot spots, then it needs to be
replaced.
15
Causes of failure
16
Excessive heat is the primary cause of dual mass
flywheel failure, as the slipping clutch
generates heat, and you can save the flywheel by
replacing the clutch.
17
Pressing the clutch violently can damage the
internal mechanisms inside the flywheel, this
leads to premature failure of the flywheel.
18
The condition of the dual mass flywheel also
depends upon the type of your driving as reckless
driving can wear them out.
19
Each dual mass flywheel is designed keeping in
mind the number of shifts it can handle in its
lifetime, if it exceeds that, then it fails.
20
Sometimes a manufacturing defect in material or
assembly can cause a failure in the dual mass
flywheel.
21
Finally
22
The dual mass flywheel is expensive to replace,
but you can make it last longer by following good
driving habits.
23
The dual mass flywheel is an integral part of the
clutch system and if it encounters any issues, it
must be immediately replaced.
24
Always ensure that you get the best quality dual
mass flywheel installed in your car.
