Buying Advice for the CAT 246B Skid Steer Loader

[MikePhua]

The CAT 246B and Its Development History
The Caterpillar 246B skid steer loader was introduced in the early 2000s as part of CAT’s B-series, a generation known for improved hydraulic performance, operator comfort, and mechanical durability. With a turbocharged 78-horsepower Cat 3044C DIT diesel engine and a rated operating capacity of 2,000 pounds, the 246B was designed to handle demanding tasks in construction, landscaping, and industrial settings. Its popularity stemmed from its balance of power, maneuverability, and serviceability, making it a staple in rental fleets and contractor yards across North America.
Caterpillar, founded in 1925, has sold millions of machines globally, and the 246B remains one of its most enduring mid-frame skid steers. The model’s open-center hydraulic system, hydrostatic drive, and quick coupler design allow it to run a wide range of attachments—from buckets and forks to augers and trenchers—with minimal downtime.
Terminology Notes

• Rated Operating Capacity (ROC): The maximum load the machine can safely lift under normal conditions.
  
• Breakout Force: The force required to dislodge material with the bucket, indicating hydraulic strength.
  
• Hydrostatic Drive: A transmission system using hydraulic fluid to transfer power from the engine to the wheels.
  
• Open-Center Hydraulics: A system where fluid flows continuously through the control valves, allowing fast response and simple design.
  

Performance Highlights and Field Reputation
Operators consistently praise the 246B for its responsive controls and rugged build. Key performance metrics include:

• ROC: 2,000 lbs
  
• Tipping Load: 4,188 lbs
  
• Bucket Breakout Force: 5,485 lbs
  
• Lift Arm Force: 4,655 lbs
  
• Hydraulic Flow: 21.9 gal/min
  
• System Pressure: 3,335 psi
  
• Operating Weight: 7,142 lbs
  

The machine’s vertical lift path makes it ideal for loading trucks and handling pallets, while its compact footprint allows it to work in confined spaces. A contractor in Alberta used his 246B for snow removal and grading, noting that the machine’s torque and traction outperformed newer models in icy conditions.
Common Issues and Diagnostic Strategies
While the 246B is known for reliability, used units may present age-related issues. Frequent concerns include:

• Hydraulic Leaks
  • Caused by worn seals or cracked hoses
    
  • Solution: Replace with OEM-grade components and inspect coupler fittings
    
• Electrical Faults in Instrument Cluster
  • Resulting from moisture intrusion or corroded connectors
    
  • Solution: Use dielectric grease and reroute harnesses away from heat zones
    
• Starter Motor Wear
  • Common in high-hour machines with repeated cold starts
    
  • Solution: Replace with heavy-duty aftermarket units and check solenoid voltage
    
• Drive Chain Stretch
  

• Leads to jerky movement or reduced travel speed
  
• Solution: Inspect tension and replace chains every 2,000 hours
  

A technician in Texas resolved a sluggish lift issue by rebuilding the hydraulic control valve and replacing the lift cylinder seals. The machine regained full responsiveness and passed a 10-hour grading test without recurrence.
Inspection Checklist for Used Units
Before purchasing a used 246B, inspect:

• Engine hours and service history
  
• Hydraulic fluid condition and filter dates
  
• Coupler wear and attachment compatibility
  
• Tire tread depth and sidewall condition
  
• Frame welds and lift arm bushings
  
• Cab electronics and safety interlocks
  
• Cooling system cleanliness and fan belt tension
  

Some buyers retrofit their 246Bs with LED work lights, joystick controls, and upgraded seat suspension. A crew in Argentina added a backup camera and cab insulation kit, improving operator comfort and safety during night operations.
Operator Anecdotes and Field Wisdom
A retired operator in Montana recalled using the 246B during a flood cleanup. The machine’s ability to switch from forks to a grapple in minutes allowed his team to clear debris and load pallets without delay. He added that the cab layout was intuitive, even for new operators.
In British Columbia, a landscaping team used the 246B to move gravel and mulch in tight residential lots. The machine’s responsive hydraulics and low ground pressure made it ideal for delicate surfaces.
Recommendations for Fleet Managers and Buyers
To ensure long-term value:

• Maintain a service log with fluid changes, filter replacements, and attachment usage
  
• Stock spare seals, filters, and electrical connectors
  
• Train operators on hydraulic flow settings and coupler safety
  
• Include drive chain inspection in seasonal service routines
  
• Coordinate with CAT support for archived service manuals and part updates
  

A fleet manager in Georgia created a skid steer performance dashboard including lift cycle count, hydraulic response rate, and operator feedback. This improved uptime and reduced attachment-related faults across his loader fleet.
Conclusion
The CAT 246B remains a dependable and versatile skid steer loader for buyers seeking performance without complexity. With proper inspection, maintenance, and thoughtful upgrades, it continues to deliver value across industries. Whether grading, lifting, or trenching, the 246B proves that legacy machines still have plenty of work left in them.
