4. Setup and Assembly

The puller can be configured with either two or three jaws depending on the application and the component being removed.

4.1. Selecting Jaw Configuration

• Two-Jaw Configuration: Suitable for diagonal pulling of smaller bearings or components where space is limited. Provides quick setup.
• Three-Jaw Configuration: Recommended for larger components, providing a stable triangular grip for secure and even pulling force.

4.2. Attaching Jaws

1. Select the desired number of jaws (two or three).
2. Align the holes on the jaws with the corresponding holes on the puller's main body.
3. Securely fasten each jaw using the provided high-strength bolts. Ensure all bolts are tightened evenly and firmly.

5. Operating Instructions

Follow these steps for safe and effective operation of the hydraulic bearing puller.

5.1. Preparation

• Ensure the workpiece is clean and free of debris.
• Verify that the oil return switch on the hydraulic cylinder is in the 'OFF' (closed) position before applying pressure.

5.2. Positioning the Puller

1. Place the puller jaws around the component to be removed, ensuring a firm and even grip.
2. Center the puller's ram against the shaft or center point of the component.
3. The puller can be operated in both vertical and horizontal orientations, allowing flexible gripping in various positions.

5.3. Applying Hydraulic Force

1. Once the puller is securely positioned, insert the operating handle into the pump body.
2. Pump the handle slowly and steadily to extend the hydraulic ram. Observe the component for movement.
3. Continue pumping until the component is safely removed. Avoid rapid or jerky movements.

5.4. Releasing Pressure

1. Once the component is removed, slowly turn the oil return switch to the 'ON' (open) position.
2. The hydraulic ram will retract, releasing the pressure.
3. Remove the puller from the workpiece.

5.5. Applications

The Hoteche 5-Ton Hydraulic Bearing Puller is suitable for a wide range of tasks, including:

• Vehicle repair (e.g., brake discs, wheel bearings)
• Gear removal
• Pulley removal
• General industrial maintenance

6. Maintenance

Regular maintenance ensures the longevity and reliable performance of your hydraulic puller.

• Cleaning: After each use, wipe down the puller with a clean cloth to remove dirt, grease, and debris.
• Lubrication: Periodically apply a light coat of machine oil to moving parts and threads to prevent rust and ensure smooth operation.
• Inspection: Regularly check for signs of wear, cracks, or damage to the jaws, bolts, hydraulic cylinder, and seals.
• Hydraulic Fluid: While the system is self-contained, monitor for any signs of hydraulic fluid leaks. If a leak is detected, discontinue use and seek professional repair.
• Storage: Store the puller in its original carrying case in a dry, cool place to protect it from environmental elements.

7. Troubleshooting

If you encounter issues with your hydraulic bearing puller, refer to the following common problems and solutions:

• Puller Not Generating Force:
  • Ensure the oil return switch is fully closed ('OFF' position).
  • Check for hydraulic fluid leaks.
  • Verify that the jaws are securely gripping the component.
• Ram Not Retracting:
  • Ensure the oil return switch is fully open ('ON' position).
  • Check for any mechanical obstructions.
• Jaws Slipping:
  • Ensure the jaws are properly seated and gripping the component firmly.
  • Consider using the three-jaw configuration for a more stable grip if currently using two jaws.
  • Clean any grease or oil from the gripping surfaces of the jaws and the component.

For issues not resolved by these steps, contact customer support.
