Installing the Inner Rear Wheel on an ASV RC-60 Track Loader

The ASV RC-60 and Its Compact Track System
The ASV RC-60 is a mid-size rubber track loader developed by ASV Inc., a Minnesota-based company founded in 1983 and later acquired by Terex. Designed for landscaping, forestry, and light construction, the RC-60 features a patented Posi-Track undercarriage system that distributes weight evenly across multiple wheels and rollers. This design minimizes ground pressure and improves traction on soft terrain.
Powered by a 60-horsepower Perkins diesel engine, the RC-60 gained popularity in North America and Australia for its maneuverability and low-impact footprint. Its undercarriage includes a series of bogie wheels, drive sprockets, and idlers—each playing a critical role in track tension and alignment.
Understanding the Inner Rear Wheel Configuration
The inner rear wheel on the RC-60 is part of the mid-roller assembly that supports the track from beneath. Unlike outer wheels, which are more accessible, the inner rear wheel is tucked between frame components and often requires partial disassembly for replacement.
Terminology annotation:

• Bogie wheel: A small wheel mounted on a pivoting arm that supports the track and absorbs terrain impact.
  
• Posi-Track system: ASV’s proprietary undercarriage design using multiple wheels and low-friction track guides.
  
• Sprocket: A toothed wheel that engages with the track lugs to drive the machine forward.
  

The inner rear wheel is mounted on a shaft that passes through the frame and is secured with a bolt and washer. Over time, this wheel can wear out due to debris intrusion, bearing fatigue, or misalignment caused by track tension issues.
Preparation and Safety Measures
Before beginning installation:

• Park the machine on a level surface and engage the parking brake
  
• Remove the track using a pry bar and tension release procedure
  
• Clean the undercarriage thoroughly to expose mounting points
  
• Use jack stands or cribbing to support the frame safely
  

In one case from Queensland, a contractor used a hydraulic jack and timber cribbing to elevate the RC-60, allowing full access to the inner wheel without removing the entire undercarriage.
Disassembly and Access Strategy
To reach the inner rear wheel:

• Remove the outer bogie wheels adjacent to the target wheel
  
• Unbolt the protective guard plate covering the wheel shaft
  
• Loosen the retaining bolt and slide the shaft out carefully
  
• Extract the worn wheel and inspect the shaft for scoring or corrosion
  

If the shaft is damaged, it should be replaced or polished before installing the new wheel. Bearings should be greased and seated properly to prevent premature failure.
In Alberta, a forestry operator found that his inner wheel had seized due to mud-packed bearings. After cleaning and replacing the wheel, he added a rubber seal to reduce future contamination.
Installation Tips and Alignment Checks
When installing the new wheel:

• Apply anti-seize compound to the shaft
  
• Align the wheel with the frame guides and insert the shaft smoothly
  
• Torque the retaining bolt to manufacturer specifications (typically 75–90 ft-lbs)
  
• Reinstall guard plates and adjacent bogie wheels
  
• Refit the track and adjust tension using the hydraulic adjuster
  

Track alignment should be verified by running the machine slowly and observing for drift or uneven wear. If the track pulls to one side, recheck wheel spacing and sprocket alignment.
Preventative Maintenance and Long-Term Care
To extend wheel life:

• Clean the undercarriage weekly, especially in muddy or sandy conditions
  
• Inspect bogie wheels for play or noise during operation
  
• Grease bearings every 100 hours or as recommended
  
• Monitor track tension and adjust as needed to prevent side loading
  

In British Columbia, a vineyard operator installed custom polyurethane wheels to reduce vibration and extend service intervals. His RC-60 ran over 1,200 hours without a single wheel replacement.
Conclusion
Installing the inner rear wheel on an ASV RC-60 requires patience, precision, and a clear understanding of the undercarriage layout. With proper preparation, clean technique, and attention to alignment, the process can restore smooth track operation and prevent future wear.
As compact track loaders continue to evolve, the RC-60 remains a testament to modular design and field serviceability—proving that even the most tucked-away components can be accessed and replaced with the right approach.
