Caterpillar 826G Scraper

• Operating weight: Roughly 65,000 to 70,000 pounds
  
• Engine: CAT 3306 diesel engine producing about 230 horsepower
  
• Bowl capacity: Around 20 cubic yards (heaped)
  
• Transmission: Powershift transmission with advanced torque converter
  
• Hydraulic system: Controls for scraper bowl elevation, apron, and ejector functions
  
• Key applications: Excavating, hauling, and spreading materials over large areas
  

Technical Terminology

• Powershift transmission: A type of automatic transmission that shifts gears under load without interrupting power flow.
  
• Load-sensing hydraulics: Hydraulic system that adjusts flow and pressure based on load demand to optimize efficiency.
  
• Bowl capacity: The volume the scraper’s bowl can hold, crucial for earthmoving productivity.
  
• Torque converter: A hydraulic coupling transmitting engine power smoothly to the transmission.
  
• Apron and ejector: Components controlling material loading and unloading in scrapers.
  

Performance and Operational Use
The 980G excels in versatile loading and material handling roles, offering:

• High breakout force for efficient digging and scooping.
  
• Smooth hydraulic response allowing precise bucket control.
  
• Durable construction suitable for rugged job sites.
  
• Operator comfort with spacious cabs and ergonomic controls.
  

The 826G scraper provides efficient earthmoving capabilities, characterized by:

• Large material capacity enabling fewer trips and higher productivity.
  
• Advanced hydraulic controls for precise bowl and ejector operation.
  
• Powerful engine and transmission combination supporting heavy loads.
  
• Good maneuverability for a machine of its size.
  

Operator Experiences and Stories
One operator recounted using the 980G to load gravel efficiently in a quarry setting, highlighting the machine’s power and responsive hydraulics for quick cycle times.
Another shared a story about working with the 826G scraper on a large highway project, praising its capacity and reliable performance despite challenging terrain and long haul distances.
Maintenance and Reliability
Both machines require diligent maintenance for sustained performance:

• Regular oil changes and filter replacements to protect engines.
  
• Hydraulic system fluid and component checks to prevent leaks and failures.
  
• Transmission servicing to ensure smooth gear changes.
  
• Inspection and replacement of wear parts such as bucket teeth and scraper cutting edges.
  
• Undercarriage and tire monitoring to maintain traction and stability.
  

Industry Relevance and Legacy
The CAT 980G and 826G models represent a generation of heavy equipment built for productivity and durability. Their balanced design and proven technology helped establish Caterpillar’s dominance in the wheel loader and scraper markets during the late 20th century.
Today, these machines are still valued by contractors for their reliability and ease of repair, often serving in secondary or specialized roles after many years of primary service.
Maintenance Checklist for 980G and 826G

• Engine oil and filter replacement schedule adherence
  
• Hydraulic fluid level and quality inspection
  
• Transmission fluid checks and servicing
  
• Visual inspections of hydraulic hoses and fittings
  
• Replacement of wear components (bucket teeth, scraper edges)
  
• Track or tire condition monitoring
  
• Electrical system diagnostics and battery maintenance
  

Conclusion
The Caterpillar 980G wheel loader and 826G scraper are robust machines tailored to complementary roles in construction and earthmoving. Their respective strengths in loading and hauling enable efficient job site workflows. Through proper maintenance and understanding of their capabilities, operators can maximize productivity and machine lifespan. Their enduring presence in various industries underscores their impact as workhorses of heavy equipment fleets.
