Champion G710 Motor Grader Spare Parts Are Still Obtainable with the Right Strategy

The Champion G710 and Its Legacy
The Champion G710 motor grader was part of a series of mid-size graders produced by Champion Road Machinery, a Canadian manufacturer with roots dating back to the early 1900s. Known for their rugged frames, mechanical simplicity, and reliable hydraulics, Champion graders were widely used in municipal road maintenance, forestry, and mining operations. The G710, in particular, was favored for its balance of power and maneuverability, often equipped with a Cummins or Detroit Diesel engine and a manual or powershift transmission.
After Champion was acquired by Volvo Construction Equipment in the late 1990s, parts support for older models like the G710 became more fragmented. However, a robust aftermarket and niche suppliers have kept these machines alive across North America, Africa, and the Middle East.
Key Components That Often Require Replacement
Owners of the G710 typically seek parts for:

• Transmission control modules and linkages
  
• Hydraulic pumps and valve blocks
  
• Steering cylinders and tie rods
  
• Brake components and master cylinders
  
• Electrical switches and wiring harnesses
  
• Engine mounts and cooling system parts
  
• Blade lift and articulation cylinders
  

Because many of these components were sourced from third-party suppliers (e.g., Eaton, Rexroth, Parker), replacements can often be found outside of OEM channels.
Strategies for Locating Obsolete Parts
To source parts for the G710:

• Identify the original part number using the Champion service manual
  
• Cross-reference with supplier catalogs from Eaton, Parker, or Dana
  
• Contact specialized grader parts suppliers who stock obsolete inventory
  
• Use salvage yards and equipment dismantlers for hard-to-find castings
  
• Consider remanufactured or rebuilt components for cost savings
  

A grader operator in Ontario successfully rebuilt his G710’s transmission using a combination of NOS (new old stock) parts and a donor unit from a retired G706. He noted that while the casing was identical, internal gear ratios required careful matching.
Recommended Suppliers and Networks
While mainstream dealers may no longer stock Champion parts, several niche providers specialize in legacy grader support:

• Independent hydraulic shops that rebuild pumps and cylinders
  
• Electrical component suppliers who match switches and relays by spec
  
• Online marketplaces with verified sellers of NOS parts
  
• Equipment forums and user groups where parts are traded or sourced
  
• Custom fabrication shops that reproduce brackets, bushings, and pins
  

In Egypt, a contractor restored a G710 by sourcing transmission control parts from a Canadian supplier who specializes in obsolete grader components. The machine was back in service within two weeks, grading access roads for a desert solar farm.
Maintenance Tips for Extending Component Life
To reduce reliance on hard-to-find parts:

• Flush hydraulic systems annually and replace filters every 500 hours
  
• Inspect electrical connectors for corrosion and apply dielectric grease
  
• Use OEM-spec fluids and lubricants to prevent premature wear
  
• Grease blade pivots, circle bearings, and articulation joints weekly
  
• Monitor transmission temperature and avoid high-load shifts
  

A fleet manager in Arizona implemented a preventive maintenance schedule for his Champion graders and reduced unscheduled downtime by 60% over three years.
When to Retrofit or Upgrade
In cases where parts are no longer available:

• Retrofit modern hydraulic valves with adapter plates
  
• Replace analog gauges with digital equivalents using universal senders
  
• Install aftermarket LED lighting and wiring harnesses
  
• Upgrade seat assemblies and cab insulation for operator comfort
  
• Replace obsolete brake systems with modular air-over-hydraulic kits
  

These upgrades not only improve reliability but also enhance resale value and operator satisfaction.
Conclusion
While Champion G710 graders are no longer in production, their legacy lives on through dedicated owners, skilled technicians, and niche suppliers. With a strategic approach to sourcing, cross-referencing, and preventive care, these machines can continue grading roads and shaping landscapes for years to come. In a world of disposable equipment, the G710 proves that well-built iron still has a place—if you know where to look and how to keep it running.
