Transmission Oil Seal 24347588759 For BMW E46 E90 E91 E60 E61 E65 E66 E87

The main reason for the existence of oil seal in automobile gearbox is to prevent the leakage of lubricating oil in gearbox. The lubricating oil in the gearbox plays the role of lubrication, cooling and sealing in the gearbox, keeping the normal operation of the internal parts of the gearbox and reducing friction. The gearbox oil seal is located at the joint between the gearbox housing and the transmission shaft, which plays the role of sealing the lubricating oil and preventing the lubricating oil from leaking to the external environment.

If the oil seal of the gearbox is damaged or aged, it will lead to the leakage of lubricating oil in the gearbox, resulting in insufficient lubrication inside the gearbox, increasing the friction of internal parts of the gearbox, and then affecting the normal operation and life of the gearbox. In addition, the leakage of lubricating oil will also lead to overheating, frustration, abnormal noise and other problems of the gearbox, which will affect the performance and driving safety of the vehicle.

Therefore, the existence of gearbox oil seal is to ensure that the lubricating oil in the gearbox does not leak, maintain the normal operation and lubrication of the gearbox, prolong the service life of the gearbox and improve the reliability and safety of the vehicle. Regular inspection and maintenance of gearbox oil seal and timely replacement of damaged oil seal are important measures to ensure the normal operation of gearbox system and prolong gearbox life.
