Introduction
The Caterpillar 14E Motor Grader, introduced in the late 1960s, represents a significant advancement in road construction and maintenance equipment. As a successor to the 12F model, the 14E incorporated several design improvements that enhanced its performance and operator comfort. Its robust construction and versatile capabilities have made it a valuable asset in various grading applications.
Specifications

• Engine: The 14E is powered by a six-cylinder, 640.8 cubic inch displacement engine, delivering a net power of 150 horsepower at 2,000 rpm.
  
• Dimensions:
  • Overall Length: 27.24 ft
    
  • Width Over Tires: 8.01 ft
    
  • Wheelbase: 20.02 ft
    
  • Blade Base: 9.03 ft
    
  • Height to Top of Isomount Cab: 10.67 ft
    
• Weight: Approximately 30,027 lbs
  
• Hydraulic System Fluid Capacity: 8.5 gallons
  

Design Features
The 14E featured several design enhancements over its predecessor:

• Hydraulic-Boosted Gear Controls: This system provided operators with improved control and responsiveness, reducing physical effort during operation.
  
• Blade Lift Gear Placement: The blade lift gears were mounted above the front wheels, improving visibility and accessibility for maintenance.
  

Maintenance Considerations
Operators have reported issues with the planetary gears within the gearbox that controls the blade's elevation. These gears, often referred to as "spider gears," can suffer from broken teeth due to wear and tear. Regular inspections and maintenance are crucial to prevent such failures.
Parts and Manuals
For those maintaining or restoring a 14E, obtaining the correct parts and manuals is essential. Reproduction operator manuals are available, providing valuable information on proper operation and preventative maintenance procedures. Parts manuals, such as the HTCT-P14E12K1, contain exploded views and part numbers to assist in sourcing the correct components.
Market Presence
Despite being discontinued, the 14E continues to be available in the used equipment market. For instance, a 1968 model was listed for sale in Fresno, California, highlighting the model's enduring presence and utility in the field.
Conclusion
The Caterpillar 14E Motor Grader remains a testament to Caterpillar's engineering excellence. Its durable design and powerful performance continue to serve operators in various grading applications. For those interested in vintage heavy equipment, the 14E offers a blend of historical value and practical functionality.
