How to Bleed Air from Hydraulic Control Valve on MF 20

If you own a MF 20 tractor and are experiencing issues with the hydraulic control valve, such as improper operation or loss of pressure, it might be necessary to bleed air from the system. Bleeding air from the hydraulic control valve is a crucial step that ensures the smooth operation and efficiency of your tractor's hydraulic system. In this article, we will provide you with a step-by-step guide on how to effectively bleed air from the hydraulic control valve on your MF 20.

Step 1: Safety Precautions

Before starting the air bleeding process, it is essential to take some safety precautions to ensure your well-being and the proper functioning of your tractor. Make sure the tractor is turned off and the engine is cool. Wear protective gloves and eye goggles to avoid any potential injuries. Additionally, ensure the tractor is on a level surface and the hydraulic system is depressurized.

Step 2: Locate Bleeder Valve

The next step is to locate the bleeder valve on the hydraulic control valve of your MF 20 tractor. The bleeder valve is typically positioned near the top or side of the control valve. Consult the operator's manual of your tractor for specific instructions on the location of the bleeder valve, as it may vary depending on the model and year of production.

Step 3: Prepare Bleeding Kit

Prepare a bleeding kit consisting of a container or absorbent material to catch any released hydraulic fluid, a wrench or socket set to loosen and tighten the bleeder valve, and a cloth or rag to clean any spills. It is also recommended to have some extra hydraulic fluid on hand in case it is needed during the bleeding process.

Step 4: Loosen the Bleeder Valve

Using the appropriate wrench or socket set from your bleeding kit, carefully loosen the bleeder valve on the hydraulic control valve. Make sure to loosen it just enough to allow air and fluid to escape, but be cautious not to remove it completely. Keep the container or absorbent material below the bleeder valve to catch any hydraulic fluid that may be released.

Step 5: Bleed the Air

Once the bleeder valve is slightly loosened, it's time to bleed the air from the hydraulic control valve. Start the tractor engine and activate the hydraulic control system. Gradually cycle the control lever or joystick associated with the valve a few times to allow the air to escape. This process will help clear any air bubbles trapped in the system, ensuring proper hydraulic function.

Step 6: Tighten the Bleeder Valve

Once you have cycled the control lever or joystick and notice a steady flow of hydraulic fluid without any air bubbles, you can proceed to tighten the bleeder valve using the wrench or socket set. Make sure to tighten it securely to prevent any potential leaks in the future.

Step 7: Check for Proper Operation

After tightening the bleeder valve, check the overall operation of the hydraulic control valve on your MF 20 tractor. Ensure that all functions associated with the valve, such as raising, lowering, or tilting, work smoothly and consistently. If any issues persist, you may need to repeat the air bleeding process or consult a professional for further assistance.

By following these step-by-step instructions, you can effectively bleed air from the hydraulic control valve on your MF 20 tractor. Remember to prioritize safety throughout the process and consult your tractor's operator manual for any specific guidance. Properly bleeding air from the hydraulic system will guarantee optimal performance and extend the lifespan of your MF 20's hydraulic control valve.
