Replacing the Rear Torsion Axle and Bearing on a CAT 259D Undercarriage
#1
The CAT 259D skid steer loader is a highly reliable and versatile machine, frequently used in construction, landscaping, and agriculture. One of the crucial components of the undercarriage system is the rear torsion axle and its bearings. If these components wear out or fail, they can lead to decreased performance, potential damage to other parts, or even a complete breakdown. This article discusses the process of replacing the rear torsion axle and bearing on the CAT 259D and provides valuable tips for successful replacement.
Understanding the Importance of the Rear Torsion Axle and Bearing
The rear torsion axle and bearing system in a CAT 259D plays a significant role in supporting the machine’s weight, providing stability, and ensuring smooth movement. This part of the undercarriage system is designed to absorb and distribute the stress from the ground, keeping the tracks in place while allowing them to adjust to different terrains.
  • Rear Torsion Axle: The torsion axle connects the tracks to the chassis and helps to manage forces exerted on the machine as it moves.
  • Bearings: The bearings allow the axle to rotate smoothly and prevent friction, which would otherwise result in excessive wear and tear.
When the axle or bearing becomes damaged or worn out, it can affect the overall performance of the skid steer, leading to uneven wear on the tracks, instability during operation, and potential damage to the rest of the undercarriage system.
Signs That the Rear Torsion Axle and Bearing Need Replacement
  1. Unusual Noises:
    If you hear grinding or squeaking sounds coming from the rear of the machine, it may indicate that the axle bearings are worn, or the axle itself is misaligned.
  2. Decreased Performance or Stability:
    A significant reduction in machine stability, particularly when turning or on uneven ground, could be a sign of a problem with the rear torsion axle. This issue may also lead to difficulty in controlling the skid steer.
  3. Excessive Vibration:
    Vibration in the rear of the machine, especially when driving over bumps or uneven terrain, can result from a failing bearing or axle. This could be due to worn components that are no longer providing the necessary support.
  4. Visible Damage:
    Cracks, dents, or visible wear on the axle or bearings are clear indicators that these components need to be replaced.
Steps to Replace the Rear Torsion Axle and Bearing on the CAT 259D
  1. Preparation:
    Before starting, ensure the machine is on stable, level ground and that the engine is turned off. Secure the skid steer with appropriate safety measures such as chocks and lifting equipment.
  2. Lift the Rear of the Skid Steer:
    Using a hydraulic jack or lifting equipment, carefully lift the rear of the machine off the ground to relieve pressure from the rear axles. Ensure that the vehicle is properly supported with jack stands or similar devices to ensure safety during the replacement.
  3. Remove the Rear Tracks:
    To access the rear torsion axle, the tracks need to be removed. This typically involves loosening the track tension and then removing the track from the machine.
  4. Remove the Axle Housing:
    To access the rear torsion axle, you must remove the housing that contains it. This may require removing bolts or fasteners that secure the housing to the skid steer’s frame. Be sure to keep track of all components for reassembly.
  5. Remove the Old Torsion Axle and Bearings:
    Once the housing is removed, carefully remove the worn torsion axle and bearings. Inspect the components for any signs of damage or excessive wear, and take note of how they were positioned to ensure the new parts are installed correctly.
  6. Install the New Torsion Axle and Bearings:
    Place the new bearings into the housing, ensuring that they are properly seated and aligned. Then, insert the new torsion axle, ensuring it fits correctly with the bearings. Make sure the axle spins freely without any obstruction or excessive play.
  7. Reassemble the Undercarriage:
    After the new components are in place, reassemble the housing and secure it with the bolts or fasteners that were removed earlier. Ensure all components are tightened to the correct torque specifications.
  8. Reinstall the Tracks:
    Once the rear axle and bearing system is fully reassembled, reinstall the tracks. Make sure the tracks are correctly aligned and tensioned according to the manufacturer’s recommendations.
  9. Test the Machine:
    After the installation is complete, lower the machine and test it. Run the skid steer at low speeds, checking for any unusual sounds or vibrations. Also, check for proper operation when turning and maneuvering the machine on uneven surfaces.
Tips for a Successful Replacement
  1. Use Quality Parts: Ensure that you’re using genuine CAT replacement parts or high-quality aftermarket components to ensure proper fit and function.
  2. Proper Alignment: Pay close attention to the alignment of the torsion axle and bearings during installation. Misalignment can cause uneven wear or premature failure of the new parts.
  3. Regular Maintenance: After the replacement, perform regular maintenance checks to ensure the new axle and bearings are functioning properly. Keep the system lubricated to prevent premature wear.
  4. Torque Specifications: Follow the manufacturer’s torque specifications when tightening bolts and fasteners. Under-tightening or over-tightening can cause damage to the components or lead to failure.
Conclusion: Maintaining the CAT 259D Undercarriage
Replacing the rear torsion axle and bearing on the CAT 259D is a critical task that helps maintain the stability and performance of the machine. By identifying the signs of failure early and replacing worn components with quality parts, operators can extend the life of their skid steer and avoid costly repairs. Regular maintenance and proper installation practices ensure that the machine will continue to perform efficiently and reliably in demanding work environments.
