V.Cleaning and Inspection of SAI Series Radial Piston Hydraulic Motors
Repair Procedures and Safety Precautions:
SAI Series radial piston hydraulic motors are known for their durability and reliability. However, like any mechanical device,
they require regular cleaning and inspection to maintain optimal performance and prevent premature failure.
Before you begin cleaning and inspecting your SAI Series radial piston hydraulic motor, it is important to take the following safety precautions:
a. Wear safety glasses and gloves at all times. Hydraulic fluid can be harmful if it comes into contact with your skin or eyes.
b. Relieve pressure from the hydraulic system before disassembly. This can be done by opening the pressure relief valve or by disconnecting the
hydraulic lines.
c. Place the motor in a clean, dry, and well-ventilated area. This will help to prevent contamination and ensure that you have a good workspace.
d. Have all necessary tools and supplies on hand. This will help to avoid delays and ensure that the job is done efficiently.
Cleaning Procedure:
a. Disassemble the motor. Refer to the SAI Series radial piston hydraulic motor service manual for specific disassembly instructions.
b. Clean the external components. Use a cleaning solvent and a lint-free cloth to remove dirt, grease, and debris from the external components of the
motor.
Be careful not to get any cleaning solvent into the internal components of the motor.
c. Clean the internal components. Use mineral spirits and compressed air to clean the internal components of the motor. Be careful not to damage any of the seals or bearings.
d. Inspect the components. Once the motor is clean, carefully inspect all of the components for signs of wear or damage.
Pay particular attention to the following:
The piston rings and cylinder walls: Look for scoring, scratches, or excessive wear.
The bearings: Look for signs of wear, pitting, or scoring.
The seals: Look for cracks, leaks, or damage.
Replace any worn or damaged components. If you find any worn or damaged components, they must be replaced before reassembling the motor.
*Tips
- When cleaning the internal components of the motor, be sure to blow out all of the compressed air before reassembling the motor.
- Do not use harsh chemicals or abrasives to clean the motor, as this can damage the components.
- If you are unsure about any of the cleaning or inspection procedures, consult a qualified hydraulics technician.
By following these steps, you can help to ensure that your SAI Series radial piston hydraulic motor continues to operate safely and efficiently for many
years to come.
