In daily life, the car has become the main travel tool, we will certainly encounter a variety of problems in the process of using. see a lot of riders mentioned the role of flywheel shell.

The flywheel housing is cast iron and is not easily deformed. It supports the clutch assembly, bears the weight of the transmission, and acts as a fulcrum for power transmission. Damage and cracking of the flywheel housing often occur in the front and rear planes, that is, the contact surface with the cylinder block and the transmission housing. The flywheel housing is installed on the beam bracket, and elastic rubber pads are installed under the two corners of the housing, which are fixed with bolts so that the flywheel housing cannot jump and shift.

The bottom of the flywheel housing is equipped with a movable bottom shell, which is convenient for removing the flywheel and clutch assembly and adjusting the clutch. A starter (motor) is also mounted on the flywheel housing. It can be seen that the function of the flywheel housing is to bear weight, position the engine and transmission, and place the starter.

Although there is not much wear, its damage and deformation have a great impact on the engine. Because the flywheel housing bears weight and external force, cracks and deformation will inevitably occur. After the flywheel housing is deformed, its parallelism and the center of the bearing hole lose the original accuracy, that is, the bearing hole of the flywheel housing cannot be concentric with the center of the crankshaft and the center of the transmission, resulting in the deviation of the center of the engine and the transmission.

This affects the transmission of electricity. The wear of the driven parts will also increase, resulting in abnormal transmission noise. The misalignment of the two planes of the flywheel housing will also bring unnecessary wear to the driven parts, such as clutch plates, transmission drive axles, bearings, etc.

The overall role of the flywheel housing is:

1. The flywheel housing is made of cast iron and is not easy to deform. It contains a clutch assembly that bears the weight of the transmission as a fulcrum for power transmission. Damage and cracks of the flywheel housing often occur on the front and rear planes, that is, on the contact surface with the cylinder block and the gearbox housing. The flywheel housing is installed on the beam bracket, and elastic rubber pads are installed under the two corners of the housing, which are fixed with bolts to prevent the flywheel housing from jumping and shifting.

2. The bottom of the flywheel housing is equipped with a movable bottom shell, which is convenient for disassembling the flywheel and clutch assembly and adjusting the clutch. The flywheel is also equipped with a starter (motor). It can be seen that the flywheel housing is used for load-bearing, positioning the engine and transmission, and placing the starter.

3. Although there is little wear, its damage, deformation, and misalignment have a great impact on the engine. Because the flywheel housing bears the weight and external force, it will inevitably produce cracks and deformation. After the flywheel housing is deformed, its parallelism and the center of the bearing hole lose their original accuracy, that is, the bearing hole of the flywheel housing cannot be concentric with the center of the crankshaft and the center of the transmission, resulting in a deviation between the center of the engine and the transmission.

This will affect the transmission of electricity. The wear of the drive components will increase, and abnormal transmission noise will occur. The misalignment of the two planes of the flywheel housing will also bring improper wear to the driven parts, such as the wear of the clutch plate, the transmission drive axle, and the bearing.
