1 Gearbox main gear with differential and bearing assembly Tesla model 3 1120970-00-F

Used Tesla Model 3 main gear assembly with differential and bearing. It is similar in design with spare parts for gasoline and diesel cars. There are radical differences in the architecture of the gearbox itself. This drastically affects the resource of the main gear and its operating conditions.¶The main gear assembly (catalog number 1104386-00-A) is lubricated not by direct flow and not by dipping into an oil bath. Gear oil enters the bearings of the Tesla gearbox by spraying through an oil nozzle. Oil is supplied to it from the oil pump. ¶The pump is driven by a plastic gear which has a limited life span. Checking the condition of the helical connection of the main gear is possible only after dismantling and inspecting the differential. The pump gear is directly driven by the differential main gear teeth. Therefore, the condition of the teeth is important for the quality of the lubrication of the entire unit.¶The replacement of the worn main gear of the differential gearbox or bearings is carried out after a detailed diagnosis of the condition. Teeth wear of more than 20% of the nominal value is not allowed. Tesla differential bearing play is also unacceptable. ¶You can buy a used Tesla Model 3 Genuine Differential Main Gear Assembly for a low price at Stock-Tesla.¶
