What is power steering bleeding?
When air bubbles get into the power steering system, they can cause a decrease in the system's pressure, making the power steering feel weak and lead to difficulty in turning the tractor. Bleeding the power steering system is a process of removing these air bubbles and replacing it with the hydraulic fluid to recover the hydraulic pressure to make your steering system work correctly.Tools and materials needed for power steering bleeding
Before you begin bleeding the power steering system on your tractor, you will need to gather the necessary equipment and materials required to do the job correctly. You will need the following tools and materials:1. Two hydraulic jacks
2. A socket wrench set
3. Clean rags
4. Container to collect used fluid
5. A quart of hydraulic fluid
Bleeding Massey Ferguson power steering system
Once you have gathered all the necessary equipment and materials, you can now begin the steps to bleed the power steering system on your Massey Ferguson tractor.Step 1: Locate the Bleeder Valve
The first step in bleeding your power steering system is to locate the bleeder valve, which can be found on the power steering pump, which is near the engine. The bleeder valve should be visible for a Massey Ferguson tractor with an open center hydraulic system.Step 2: Clean the Area
The next step is to clean the surrounding area of the bleeder valve, where you will be applying the socket wrench. Ensure the area is clean to prevent any contaminations of dirt, debris, or water that may enter the power steering pump.Step 3: Position the Jacks
Position the two hydraulic jacks under the tractor, ensuring they are placed on stable surfaces that can hold the weight of the tractor. The jacks will be used to raise the front of the tractor to allow you to turn the steering wheel.Step 4: Fill the Reservoir
Add the hydraulic fluid to the power steering system reservoir, which can be located under the hood. Check the tractor's manual for the exact amount of fluid to use.Step 5: Turn the Steering Wheel
With the engine running, turn the steering wheel fully to the left and hold it there for a few seconds. Then turn it to the right and hold it there for a few seconds before returning it to the center position.Step 6: Bleed the System
Loosen the bleeder valve on the power steering pump a few turns, allowing the air bubbles to escape. You will see the hydraulic fluid coming out of the valve, which indicates that the air is escaping. Close the valve to prevent the air from getting into the system. Repeat the process of turning the steering wheel from left to right and then center again.Step 7: Check the Fluid Level
Check the hydraulic fluid reservoir level to ensure it has sufficient fluid. Repeat process until there's no air coming out, then tighten the bleeder valve. Start the engine and turn the wheels to ensure there's no stiff steering.
