How to repair and maintain the wheel loader gearbox?

Use the correct oil for the transmission system, and the lubricating oil used by the gearbox must meet the specifications. It should be noted that diesel engine oil cannot be added to the gearbox, because diesel oil will reduce the friction between moving parts (such as pistons), and the oil used in the transmission system must allow the friction between the friction plates to reach a certain amount. The friction force when combined together is essential for the normal operation of the transmission system of the small front end loader. Only the correct use of lubricating oil can effectively extend the service life of the clutch friction plate. At the same time, the correct use of oil can significantly improve the anti-wear performance of gears, eliminate clutch slipping, control brake tremor and abnormal noise, increase braking force, and provide greater traction. At present, most of the hydraulic transmission oils for gearboxes are 6# and 8# hydraulic transmission oils.
