Case 1845C Skid Steer Loader Reliability Performance and Field Maintenance

[MikePhua]

The 1845C and Case’s Skid Steer Legacy
The Case 1845C skid steer loader was introduced in the late 1980s and remained in production until the early 2000s, marking one of the longest-running and most successful models in Case Construction’s history. With over 60,000 units sold globally, the 1845C became a staple in agriculture, construction, landscaping, and municipal fleets. Its reputation for mechanical simplicity, rugged build, and ease of service made it a favorite among owner-operators and rental yards alike.
Case Corporation, founded in 1842 and later merged into CNH Industrial, pioneered compact equipment with a focus on durability and operator ergonomics. The 1845C was powered by a Cummins 4B 3.9L diesel engine, delivering around 60 horsepower and paired with a chain-driven mechanical drive system. Its rated operating capacity hovered around 1,750 lbs, with a tipping load of approximately 3,500 lbs.
Core Specifications and Operating Features
Key performance metrics:

• Engine: Cummins 4B 3.9L, 4-cylinder diesel
  
• Rated power: ~60 hp at 2,500 rpm
  
• Operating weight: ~5,800 lbs
  
• Lift capacity: ~1,750 lbs
  
• Hydraulic flow: ~15 gpm
  
• Travel speed: ~7 mph
  
• Tire size: 10x16.5 standard
  

The 1845C features a vertical lift path, making it ideal for loading trucks and stacking pallets. Its mechanical chain drive system uses dual chains per side, housed in sealed compartments, offering reliable torque transfer with minimal maintenance. The loader arms are robust and reinforced, and the cab layout is simple, with mechanical levers for drive and lift functions.
In one fleet in Alberta, a 1845C was used for snow removal and gravel grading. The operator reported that even after 8,000 hours, the machine started reliably and performed without major hydraulic issues.
Common Issues and Practical Solutions
Despite its reputation for durability, the 1845C has a few recurring issues that owners should monitor:

• Hydraulic lift hesitation
  Caused by worn pump seals or low fluid levels.
  Solution: Replace seals, flush system, and use ISO VG 46 hydraulic oil.
  
• Chain case leaks
  Often due to worn axle seals or overfilled compartments.
  Solution: Replace seals, inspect breather ports, and maintain correct oil level.
  
• Electrical faults
  Starter solenoid and ignition switch may fail due to vibration.
  Solution: Upgrade to marine-grade connectors and install vibration dampers.
  
• Fuel system airlocks
  Resulting from cracked lines or loose clamps.
  Solution: Replace fuel lines with reinforced hose and install inline check valve.
  
• Drive chain tension loss
  Chains may stretch over time, causing slippage.
  Solution: Adjust tension using factory procedure and inspect sprockets for wear.
  

In one rebuild in Texas, a technician resolved a lift delay by replacing the hydraulic filter and cleaning the valve block. The loader returned to full responsiveness within an hour.
Maintenance Strategy and Service Intervals
Routine maintenance is key to extending the life of the 1845C:

• Engine oil and filter: Every 250 hours
  
• Hydraulic fluid and filter: Every 500 hours
  
• Chain case oil: Every 1,000 hours or annually
  
• Fuel filter: Every 250 hours
  
• Air filter: Inspect every 100 hours
  
• Drive chain tension: Inspect quarterly
  
• Tire pressure: Weekly check
  

Recommended upgrades:

• Install LED work lights for night operations
  
• Add quick-connect hydraulic couplers for attachments
  
• Retrofit seat with suspension and lumbar support
  
• Use synthetic engine oil in cold climates
  
• Label fuse panel and keep spare fuses onboard
  

In one municipal fleet in Maine, switching to synthetic hydraulic fluid reduced pump wear and improved cold-start performance during winter operations.
Operator Experience and Ergonomic Feedback
Operators consistently praise the 1845C for:

• Simple and intuitive controls
  
• Reliable cold-weather starting
  
• Stable ride on uneven terrain
  
• Easy access to service points
  
• Strong lift force for its size
  

In one grading job in Chile, the 1845C was used to spread crushed stone on a rural road. The operator completed the task without needing a second pass, thanks to the loader’s consistent lift and bucket control.
Parts Availability and Ownership Value
The 1845C benefits from strong aftermarket support, with parts available from CNH Industrial, salvage yards, and independent suppliers. Common parts like filters, seals, and chains are widely stocked, while more specialized components like hydraulic valves or control levers may require sourcing from legacy dealers.
Pros:

• Proven reliability across decades
  
• Simple mechanical systems
  
• Strong resale value in rural markets
  
• Easy to repair with basic tools
  

Cons:

• No factory cab HVAC in most units
  
• Chain case service requires partial disassembly
  
• Electrical system lacks modern diagnostics
  
• Hydraulic flow may be insufficient for high-demand attachments
  

In one farm operation in Tennessee, a 1845C was purchased for $12,000 with 3,500 hours. After minor repairs to the chain case and fuel system, the machine performed reliably for five years before being sold at a profit.
Conclusion
The Case 1845C skid steer loader remains a benchmark in compact equipment design. With its mechanical simplicity, durable drivetrain, and responsive hydraulics, it continues to serve operators in demanding environments. Whether grading gravel, lifting pallets, or clearing snow, the 1845C proves that reliability and performance can endure across generations—especially when backed by thoughtful maintenance and practical upgrades.
