2. Setup and Installation
Before operating the Sealey PS990 Hydraulic Ram, ensure it is correctly set up and installed with a compatible hydraulic puller set. Proper installation is crucial for safe and effective operation.
2.1 Compatibility Check
This hydraulic ram is designed to integrate seamlessly with Sealey hydraulic puller sets, including models PS980, PS981, PS982, PS985, and VSE127H. Verify that your puller set is compatible before attempting installation.
2.2 Installation Steps
- Inspect Components: Before assembly, carefully inspect the hydraulic ram and your puller set components for any signs of damage, wear, or missing parts.
- Attach to Puller: Securely attach the PS990 hydraulic ram to the designated mounting point on your hydraulic puller frame. Ensure all connections are tight and stable.
- Position Workpiece: Place the bearing, pulley, or shaft to be removed in the puller's jaws, ensuring it is centered and stable.
- Initial Engagement: Adjust the puller's arms to firmly grip the workpiece. The ram's screw mechanism should be aligned with the center of the item to be pressed or pulled.
Safety Note: Always ensure the workpiece is stable and the puller is securely positioned before applying force. Wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
3. Operating Instructions
The Sealey PS990 Hydraulic Ram operates by converting rotational force from its screw mechanism into linear hydraulic pressure, enabling the removal of tightly fitted components.
3.1 Applying Force
- Engage Screw Mechanism: Once the ram is properly installed and the workpiece is secured, use the T-handle to turn the screw mechanism.
- Apply Gradual Pressure: Turn the handle clockwise to extend the ram and apply gradual, steady pressure to the workpiece. Avoid sudden or excessive force.
- Monitor Progress: Observe the workpiece as pressure is applied. The component should begin to move or separate from its seating.
- Release Pressure: Once the component is removed, turn the T-handle counter-clockwise to retract the ram and release the pressure.
Important: Do not exceed the 10-tonne load capacity of the ram. If the component does not move with reasonable force, re-evaluate the setup or consider alternative methods. Never use impact tools on the ram's screw mechanism.
4. Maintenance and Care
Regular maintenance ensures the longevity and reliable performance of your Sealey PS990 Hydraulic Ram.
4.1 Cleaning
- After each use, wipe down the ram with a clean, dry cloth to remove dirt, grease, and debris.
- For stubborn grime, use a mild degreaser, ensuring no harsh chemicals come into contact with seals or hydraulic fluid.
4.2 Lubrication
- Periodically apply a light coat of machine oil to the screw mechanism to ensure smooth operation and prevent corrosion.
- Check for any signs of hydraulic fluid leaks. If leaks are detected, discontinue use and consult a qualified technician.
4.3 Storage
- Store the hydraulic ram in a clean, dry environment, away from direct sunlight and extreme temperatures.
- Ensure the ram is fully retracted before storage to protect the piston rod.
5. Troubleshooting
If you encounter issues with your Sealey PS990 Hydraulic Ram, refer to the following common problems and solutions.
5.1 Ram Not Extending or Applying Sufficient Force
- Check Compatibility: Ensure the ram is used with a compatible puller set and that all connections are secure.
- Inspect Screw Mechanism: Verify that the screw mechanism is clean and lubricated, allowing for smooth rotation.
- Overload: The workpiece may require more than 10 tonnes of force. Do not attempt to exceed the ram's rated capacity.
5.2 Hydraulic Fluid Leakage
- Inspect Seals: Check for visible damage to seals around the piston rod or connections.
- Tighten Connections: Ensure all hydraulic connections are properly tightened.
- Professional Repair: If leakage persists, the unit may require professional servicing or seal replacement. Do not attempt to repair internal hydraulic components unless qualified.
