What Can You Tell Me About the Case 855E

[MikePhua]

Legacy of Case Corporation
Founded in 1842 by Jerome Increase Case, Case Corporation began as a manufacturer of threshing machines and quickly evolved into one of the most influential names in construction and agricultural equipment. By the mid-20th century, Case had become synonymous with rugged reliability, particularly in the loader and dozer segments. The 855E, part of Case’s long-standing track loader lineage, emerged during a period when the company was refining hydrostatic drive systems and ergonomic operator stations to meet the demands of increasingly complex job sites.
Development and Market Position of the 855E
The Case 855E track loader was introduced in the late 1980s as an evolution of the earlier 855 series. It was designed to bridge the gap between mid-size dozers and compact loaders, offering a balance of power, maneuverability, and versatility. The “E” designation marked improvements in hydraulic responsiveness, operator comfort, and drivetrain efficiency. While exact production numbers are not publicly disclosed, industry estimates suggest that thousands of units were sold globally, particularly in North America and parts of Europe, where Case had strong dealer networks.
Core Specifications and Performance
The Case 855E typically features:

• Operating weight: Approximately 18,000 to 20,000 lbs (8,165 to 9,072 kg)
  
• Engine: Case 6T-590 turbocharged diesel engine
  
• Horsepower: Around 90 to 95 HP (67 to 71 kW)
  
• Transmission: Hydrostatic drive with dual-path control
  
• Bucket capacity: Roughly 1.5 to 2.0 cubic yards (1.15 to 1.53 m³)
  
• Track type: Standard steel grousers with optional rubber pads
  

Terminology Annotation

• Hydrostatic Drive: A transmission system that uses hydraulic fluid to transfer power from the engine to the tracks, allowing for smooth variable speed control and precise maneuvering.
  
• Dual-path Control: Independent control of left and right track drives, enabling zero-radius turns and enhanced agility in confined spaces.
  
• Grousers: Raised bars on steel tracks that improve traction on soft or uneven terrain.
  

Operator Experience and Ergonomics
One of the most distinctive features of the 855E is its center-mounted shifter located between the operator’s legs. While unconventional, this design was intended to reduce lateral arm fatigue and keep the operator’s hands closer to the steering and hydraulic controls. Some users found it awkward initially, but many appreciated the compact layout once accustomed.
The cab itself was designed with visibility and comfort in mind. Large glass panels, adjustable suspension seat, and intuitive control levers made long shifts more bearable. Noise insulation was modest by today’s standards but considered acceptable at the time.
Common Applications and Field Anecdotes
The 855E was widely used in:

• Road construction and grading
  
• Land clearing and site preparation
  
• Utility trenching and backfill
  
• Demolition and debris handling
  

In Missouri, a contractor named Dale used his 855E for over a decade to clear brush and build access roads for rural properties. He recalled how the machine’s torque allowed him to push through thick clay without bogging down, even during wet spring seasons. “It wasn’t the prettiest loader,” he said, “but it never let me down.”
Maintenance and Reliability
The 855E earned a reputation for mechanical simplicity and durability. Key maintenance points include:

• Regular hydraulic fluid checks and filter replacements
  
• Track tension adjustments every 100 hours
  
• Engine oil changes every 250 hours
  
• Cooling system flushes annually
  

One common issue reported by owners was wear in the final drive seals, especially in sandy environments. Replacing these seals required partial disassembly of the track assembly, which could be labor-intensive. However, Case provided detailed service manuals and parts availability remained strong through the 2000s.
Modern Comparisons and Market Evolution
Compared to today’s Tier 4 Final compliant loaders, the 855E lacks electronic engine management and emissions controls. However, its mechanical fuel injection system is easier to service in remote areas. Modern loaders like the Case 850M or Caterpillar 963K offer more horsepower, joystick controls, and telematics, but also come with higher maintenance costs and complex diagnostics.
Resale and Collector Interest
As of recent years, used Case 855E units have been listed between $10,000 and $25,000 depending on condition, hours, and attachments. Machines with rebuilt engines and undercarriages command higher prices. Some collectors and restoration enthusiasts seek out 855Es for their historical value and mechanical purity.
In 2021, a restored 855E was featured at a vintage equipment show in Iowa, drawing attention from younger operators curious about pre-electronic loaders. The owner had repainted the machine in its original Case Power Yellow and installed LED work lights for modern usability.
Recommendations for Prospective Buyers
If considering a Case 855E today, here are some tips:

• Inspect the undercarriage thoroughly, especially sprockets and rollers
  
• Test the hydrostatic drive for smooth acceleration and deceleration
  
• Check for hydraulic leaks around the control valves and lift cylinders
  
• Review service records if available, focusing on engine rebuilds and track replacements
  
• Consider sourcing parts from Case IH or aftermarket suppliers with legacy support
  

Conclusion
The Case 855E stands as a testament to late-20th-century engineering—robust, straightforward, and built for hard work. While it may lack the digital sophistication of newer models, its mechanical integrity and field-proven design continue to earn respect among operators and collectors alike. Whether clearing land in the Midwest or grading roads in Appalachia, the 855E remains a symbol of Case’s enduring legacy in the earthmoving world.
