What are the symptoms of a damaged flywheel?
1 Answers
When a car's flywheel is damaged, it will cause abnormal noises from the engine during operation, accompanied by noticeable vibrations, and can also lead to an imbalance in the transmission shaft of the gearbox. The car flywheel is a disc-shaped component with a large moment of inertia, functioning like an energy storage device. Since the power strokes of each cylinder in the engine are not continuous, the engine speed fluctuates. When the engine speed increases, the flywheel's kinetic energy rises, storing energy. Conversely, when the engine speed decreases, the flywheel's kinetic energy reduces, releasing the stored energy. The flywheel helps minimize speed fluctuations during engine operation. The car flywheel is mounted at the rear end of the engine crankshaft. Through the clutch installed on the flywheel, it connects the engine to the vehicle's transmission system and engages with the starter motor to facilitate engine starting. Additionally, it serves as the integration point for the crankshaft position sensor and vehicle speed sensor. Methods to determine flywheel damage: Check if the starter ring gear on the flywheel is intact. If the ring gear shows severe wear at the tooth ends or broken teeth, the starter ring gear or the entire flywheel needs replacement. Inspect the flywheel surface for severe burns, impact marks, scratches, etc. If such damage is present, the flywheel must be replaced. Measure the wear depth of the grooves. If it exceeds 0.5mm, it indicates the flywheel is damaged and requires replacement.
