how to remove air from tractor hydraulic system

Tractors are very useful in the field of agriculture as they help in tilling, plowing, harvesting, and transporting crops. One of the vital components in a tractor is the hydraulic system that controls the movement of the equipment. The hydraulic oil used in the system becomes contaminated with time and air enters the system, causing the system to malfunction. In this article, we discuss the process of removing air from a tractor hydraulic system.

Step 1: Identify the Source of Air

Before beginning any work on the hydraulic system, you should try to identify the source of the air. It could be from a damaged seal, a loose connection, or low hydraulic fluid levels. Once you have identified the source, rectify it before starting the air removal process. This will prevent the recurrence of the problem.

Step 2: Fill the Hydraulic System with Fresh Fluid

Next, you need to connect the hydraulic system to a good quality hydraulic fluid. Before filling the system with fresh fluid, ensure that the reservoir is empty and clean. Replace the filters if they are dirty or damaged. Fill the reservoir with fresh fluid until it reaches the recommended level.

Step 3: Bleed the Air from the System

After filling the hydraulic system with fresh fluid, you need to bleed the air from the system. To bleed the air, you have to locate the bleed screw on the hydraulic cylinder or pump. Start the tractor and turn the steering wheel or the hydraulic pump lever back and forth to circulate the fluid through the system. Loosen the bleed screw until the air bubbles escape with fluid. Tighten the screw and continue pumping the steering wheel or hydraulic lever until no air bubbles come out of the screw.

Step 4: Monitor the System

After bleeding the air from the hydraulic system, you should monitor the system for any signs of further air entry. Check hydraulic cylinders, hoses, and connections for any leaks. If you find any leakages, fix them before continuing to use the tractor.

Conclusion

In conclusion, removing air from the tractor hydraulic system is an important maintenance task that will keep your tractor working efficiently. Always ensure that the hydraulic system has fresh, clean fluid and that there are no air leaks before you begin working. By following these simple steps, you can remove air from the hydraulic system and improve the tractor's overall performance.
