Hough H60C Rear Hub Removal: Techniques, Tips, and Best Practices

[MikePhua]

Removing the rear hub on a Hough H60C wheel loader is a crucial maintenance task that can be challenging due to the hub’s robust construction and tight assembly. Proper removal techniques ensure safe disassembly, prevent damage, and prepare the machine for repairs such as bearing replacement or seal changes. This article outlines effective methods, common obstacles, and expert advice drawn from field experiences to assist technicians working on the Hough H60C rear hub.
Understanding the Rear Hub Assembly
The rear hub on the Hough H60C serves as the mounting point for the rear wheel and houses important components like bearings, seals, and brakes. Its design integrates heavy-duty parts to support the machine’s weight and torque demands.
Common Challenges in Hub Removal

• Corrosion and Rust: Long-term exposure to dirt and moisture can cause components to seize or bind, making removal difficult.
  
• Tight Fittings: Precision machining and tight tolerances require careful handling to avoid damaging splines, seals, or bearing races.
  
• Heavy Components: The hub and related parts are heavy and may require specialized lifting equipment for safe removal.
  

A technician shared a story of removing a Hough H60C hub where excessive rust required penetrating oil and gentle tapping over several hours before the hub finally loosened without damage.
Step-by-Step Removal Tips

• Safety First: Use appropriate personal protective equipment and ensure the machine is properly supported.
  
• Remove Wheel and Brake Components: Detach the wheel and brake caliper or drum to access the hub.
  
• Loosen Retaining Hardware: Remove nuts, bolts, or snap rings securing the hub assembly.
  
• Apply Penetrating Oil: Liberally apply oil to corroded areas and allow time for penetration.
  
• Use Correct Tools: Employ hub pullers, slide hammers, or hydraulic presses as recommended to avoid prying with excessive force.
  
• Work Slowly and Evenly: Gradual, even pressure helps prevent warping or cracking.
  

Maintenance and Inspection After Removal
Once removed, inspect bearings for wear, seals for leaks, and the hub for cracks or scoring. Replace damaged components promptly to ensure reliability upon reassembly.
Industry Best Practices
Experienced mechanics recommend scheduling rear hub inspections as part of regular maintenance intervals. Proper cleaning, lubrication, and protective coatings can minimize corrosion and ease future removals.
Historical Note
The Hough brand, now part of larger equipment manufacturers, is known for rugged wheel loaders widely used in construction and quarrying. Maintenance procedures like hub removal reflect the blend of heavy-duty engineering and practical serviceability designed into these machines.
Conclusion
Removing the rear hub on a Hough H60C loader demands patience, proper tools, and a methodical approach to overcome challenges like corrosion and tight fittings. Adhering to safety protocols and best practices minimizes damage and prepares the machine for effective repairs. Drawing from hands-on experience and technical knowledge, technicians can confidently handle this task and maintain the loader’s performance and safety.
