What are the causes of transmission oil leakage?
1 Answers
Transmission oil leakage can be caused by aging and deformation of oil seals, damage to the joint surface of the transmission case, etc. The specific reasons are as follows: Aging and deformation of oil seals: If the oil seal spring falls off or the oil seal is installed in the wrong direction, the oil seal will lose its oil-blocking function. In such cases, the aged and deformed oil seal should be replaced, and attention should be paid to the installation direction of the oil seal. The side with the spring coil should face the side with oil. Damage to the joint surface of the transmission case: An appropriately thicker paper gasket should be added at the damaged area. If oil leakage persists, welding repair should be performed. Damage to the front joint surface of the bearing: Or loose fastening screws and a blocked transmission vent hole. When the transmission is operating, it is isolated from the external atmosphere, causing an increase in internal pressure, which also leads to oil seeping from the blocked area.
