In advance, loader drivers must pay attention to these equipment inspection items

Before changing the oil, drive the motor grader for about 10 kilometers to ensure that the hydraulic transmission system of the entire machine is fully circulated and the oil temperature of the transmission reaches around 40℃ (so that the oil can be drained thoroughly). Stop the motor grader on a flat surface.

2. Place the gear selector in neutral and apply the handbrake tightly. If conditions permit, wedges can be used to fix the tires of the motor grader to prevent accidents.

3. Loosen the oil filler hose (also known as the oil drain pipe) at the bottom of the transmission and drain the transmission oil from the bottom. At the same time, ensure the cleanliness of the rubber hoses and joints at the bottom of the transmission, and prevent rainwater from seeping in during rainy days to avoid emulsification of the oil.

4. At the same time, open the rear grille of the engine hood and loosen the return oil pipe connecting the radiator and the transmission.

5. Increase the height of the connection hose opening to facilitate the maximum drainage of old oil.

After draining the old oil, install a rubber hose to add filtered multi-grade diesel (engine oil) from the oil filler cup to the transmission oil bottom. It is necessary to add in time to ensure that the specified quantity is reached.

7. Start the motor grader and let it idle. Let the hydraulic transmission system circulate and discharge the original system oil from the return oil port of the radiator until new oil appears at the return oil port of the radiator.
