Known for its powerful engine, durability, and versatility, this grader was designed to handle a variety of heavy-duty applications, including road maintenance, grading, and earth-moving tasks. Though it is no longer in production, the Fiat-Allis 14B remains a reliable machine for operators who work with older equipment.
In this article, we’ll explore the history of Fiat-Allis as a brand, the technical specifications and features of the 14B model, its performance, maintenance, and common issues, as well as its relevance in today’s market.
History of Fiat-Allis
Fiat-Allis was a brand formed as a result of the partnership between Fiat Trattori and Allis-Chalmers, two heavy machinery manufacturers. Established in the 1970s, Fiat-Allis focused on creating durable, high-performance construction equipment like wheel loaders, backhoe loaders, bulldozers, and motor graders. The 14B motor grader was one of their standout models, offering a reliable solution for earth-moving professionals across the globe.
In the mid-1980s, Fiat-Allis was acquired by Case Corporation, which eventually led to the discontinuation of the Fiat-Allis brand. Despite the merger and the shift in brand identity, the machines that were once part of the Fiat-Allis lineup continue to be used in various industries due to their reliability and strong construction.
Fiat-Allis 14B Technical Specifications
The Fiat-Allis 14B motor grader is a product of its time, featuring an array of specifications that made it a top choice for heavy construction work.

1. Engine:
   • Engine Type: The Fiat-Allis 14B is powered by a Cummins NTA885-C diesel engine.
     
   • Horsepower: The engine delivers approximately 150 horsepower, making it more than capable of handling heavy-duty grading tasks with ease.
     
   • Engine Capacity: With a 6-cylinder, turbocharged configuration, the engine was designed to provide optimal power while maintaining fuel efficiency.
     
   • Fuel Tank Capacity: The grader is equipped with a substantial fuel tank, typically around 100 gallons (379 liters), allowing for longer operational hours in the field before refueling is needed.
     
2. Hydraulics and Performance:
   • Hydraulic System: The 14B features a high-flow hydraulic system, enabling the efficient operation of its blade and attachments. This hydraulic system ensures precise control during grading and cutting operations.
     
   • Blade Length: The grader is typically equipped with a 14-foot (4.27 meters) moldboard, providing sufficient reach for leveling and grading tasks across large areas.
     
   • Blade Lift and Tilt: The blade can be lifted and tilted to varying degrees, allowing the operator to perform different tasks such as cutting, sloping, and spreading material.
     
   • Operating Weight: The Fiat-Allis 14B motor grader weighs approximately 23,000 lbs (10,433 kg), which gives it the necessary stability when working on uneven terrain.
     
3. Dimensions:
   • Overall Length: The overall length of the grader is about 28 feet (8.53 meters), which contributes to its stability.
     
   • Width: The grader’s width can vary based on the moldboard’s position but typically ranges around 8 feet (2.44 meters).
     
   • Height: The height of the machine is generally around 11 feet (3.35 meters), with a relatively low profile to fit into various worksite conditions.
     
4. Transmission and Axles:
   • The 14B uses a powershift transmission, allowing smooth shifting of gears without the need to engage a clutch. This feature enhances the grader’s performance, especially in demanding applications where quick and efficient speed control is necessary.
     
   • The motor grader is equipped with multiple axles designed for stability on uneven ground and better weight distribution during operations.
     

Performance and Capabilities

1. Versatility:
   The Fiat-Allis 14B is highly versatile and can handle various tasks such as road leveling, site preparation, and material spreading. Its ability to adjust the moldboard angle, lift the blade, and change tilt allows operators to handle a range of grading and excavation activities with precision.
   
2. Maneuverability:
   Despite its larger size and weight, the 14B is relatively easy to maneuver, thanks to its tight turning radius and responsive hydraulic system. This makes it ideal for road construction projects where the ability to make sharp turns and navigate tight spaces is crucial.
   
3. Productivity:
   The 14B was designed for productivity and longevity. Its large fuel tank, reliable engine, and high-capacity hydraulic system allow it to run for extended periods without frequent downtime, boosting overall productivity on construction sites.
   
4. Durability:
   Built for heavy-duty applications, the Fiat-Allis 14B is known for its durable components and sturdy frame. The machine’s robust design makes it suitable for challenging environments, such as mining and heavy grading operations, where harsh conditions demand tough equipment.
   

Common Issues and Maintenance
While the Fiat-Allis 14B is a reliable motor grader, as with any machine, it can experience certain issues over time, especially as it ages. Here are some common maintenance concerns and tips for keeping the grader in optimal working condition:

1. Hydraulic Leaks:
   The hydraulic system, while efficient, is prone to leaks over time. Regular inspection of hydraulic hoses and fittings is essential to prevent oil loss and ensure the system operates smoothly.
   
2. Transmission Wear:
   The powershift transmission, though robust, can experience wear, particularly with improper maintenance or excessive strain. Regular checks of fluid levels and the health of the transmission system will help prevent premature failure.
   
3. Engine Maintenance:
   The engine, being the heart of the motor grader, requires regular maintenance. Check the air and fuel filters, and ensure the cooling system is functioning properly to avoid overheating. Keeping the engine clean from dust and debris will also extend its lifespan.
   
4. Blade Alignment:
   Over time, the blade may require adjustment, particularly after extensive use on uneven terrain. Ensuring proper alignment of the moldboard ensures effective grading and prevents unnecessary wear.
   
5. Tire and Undercarriage Care:
   The undercarriage, including the tires and axles, should be inspected for wear, particularly in rough or rocky environments. Worn-out tires and axles can compromise performance, so they must be replaced when necessary.
