a. If the axle gearbox is filled with too much oil, it may cause oil leakage. In the event of a leak, check the oil level first.
b. It is a normal phenomenon that there is a little oil drop on the labyrinth seal of the gearbox, and it is not a serious problem. It should be observed continuously.
c. There are oil droplets on the gear box, if there is any leakage in the box, a more detailed inspection is required
(2) Visually confirm that the C-shaped bracket, bolts and rubber joints are not loose or damaged.
(3) Visually confirm that the oil level of the gearbox is between the highest line and the bottom line through the oil level observation hole. If it does not meet the standard, visually check the sealing status of both sides of the input end and output end of the gearbox to confirm that there is no obvious leakage Phenomenon, add lubricating oil to the standard range of the oil level gauge.
(4) EMUs put into use with an operating mileage of 20,000 kilometers for the first oil change. — motor roller China
