Flywheel
A heavy rotating disc attached to the engine's crankshaft that stores rotational energy.
The flywheel stabilizes engine rotation by storing kinetic energy and smoothing out combustion pulses. It also provides a friction surface for the clutch and houses the starter ring gear. Worn or cracked flywheels cause vibration and clutch chatter. Machining or replacing ensures smooth engagement and balanced performance. Dual-mass flywheels absorb vibrations for modern vehicles, improving drivability but requiring precise installation. Maintaining flywheel integrity ensures smooth acceleration and reduced drivetrain wear.
