1. Configuració

Before commencing any work, ensure all components of the SKF TMIP 7-28 kit are present and in good condition. Familiarize yourself with the parts:

1.2 Selecting the Correct Extractor:

1. Identify the inner bore diameter of the bearing to be dismounted.
2. Select the internal extractor from the kit that matches or is slightly smaller than the bearing's inner bore diameter. The extractor's claws must be able to fit into the bearing bore and expand to grip the inner ring securely.

1.3 Assembling the Puller:

1. Thread the selected internal extractor onto the end of the sliding hammer shaft. Ensure it is securely tightened.
2. Verify that the extractor's claws are free to move and expand.

2. Instruccions de funcionament

Follow these steps carefully to dismount internal bearings using the SKF TMIP 7-28 kit. Always wear appropriate personal protective equipment (PPE), such as safety glasses and gloves, during operation.

1. Prepare the Bearing: Ensure the area around the bearing is clean and free from obstructions.
2. Inseriu l'extractor: Insert the assembled extractor into the bore of the bearing. Push the extractor firmly until its claws pass through the bearing's inner ring.
3. Engage the Claws: Once the claws are past the inner ring, the spring-loaded mechanism will cause them to expand and grip the inner ring from behind. You may need to gently pull back on the sliding hammer to ensure a secure engagement. The claw design is intended to provide a strong and secure grip.
4. Operate the Sliding Hammer: Hold the sliding hammer firmly with one hand on the handle. With the other hand, slide the hammer weight forcefully towards the handle. This action generates an impact force that pulls the bearing out of its housing.
5. Repetiu segons sigui necessari: Continue to slide the hammer weight until the bearing is fully dismounted from the housing. Apply consistent and controlled force.
6. Remove the Bearing and Tool: Once the bearing is free, carefully remove it and then detach the extractor from the bearing.

Precaució de seguretat: Avoid excessive force that could damage the bearing, housing, or the tool itself. Ensure a stable working environment.

3. Manteniment

Proper maintenance ensures the longevity and reliable performance of your SKF TMIP 7-28 Internal Bearing Puller Kit.

• Neteja: After each use, clean all components of the puller kit, especially the extractors, to remove any grease, dirt, or debris. Use a clean cloth and a suitable degreaser if necessary.
• Inspecció: Regularly inspect the extractors for signs of wear, deformation, or damage to the claws. Check the sliding hammer shaft and handle for any cracks or bends. Replace any damaged components immediately to prevent injury or further damage during use.
• Lubricació: A light coat of oil can be applied to the sliding hammer shaft to ensure smooth operation. Avoid over-lubrication, which can attract dirt.
• Emmagatzematge: Store the puller kit in its original case or a suitable protective container in a dry, clean environment. This prevents corrosion and protects the components from physical damage.

4. Solució De Problemes

If you encounter issues while using the SKF TMIP 7-28, consider the following common problems and solutions:

• Bearing does not dismount:
  • Ensure the correct size extractor is used and its claws are securely gripping the bearing's inner ring.
  • Verify that sufficient force is being applied with the sliding hammer.
  • Check for any obstructions preventing the bearing from moving.
• Extractor slips from the bearing:
  • The extractor might be too small for the bore, or its claws are worn. Select a larger extractor if available, or inspect the current one for damage.
  • Ensure the extractor is fully inserted and the claws have properly engaged behind the inner ring.
• Difficulty assembling components:
  • Check for cross-threading when attaching the extractor to the sliding hammer. Ensure threads are clean and aligned.
  • Inspect components for damage or debris that might prevent proper assembly.
