Case Terratrac 600 Crawler Dozer Repair Manual

The Case Terratrac 600 crawler dozer was produced between 1957 and 1959 as part of Case’s early Terratrac line. Built as a mid-size crawler tractor, it combined rugged engineering with a Continental 4-cylinder diesel engine delivering 62 horsepower, and was also available in a gasoline configuration. Designed for reliability and durability, the Terratrac 600 served in agriculture, construction, and industrial applications.

General Specifications
With an operating weight of approximately 10,020 lb and equipped with 14-inch tracks, the Terratrac 600 was engineered for traction and stability. Its open operator station reflected the straightforward, serviceable design approach of the late 1950s.

Engine
The Continental 3.4 L 4-cylinder diesel engine powered the 600, providing steady torque and reliable performance for pushing and grading tasks. The gasoline variant offered similar characteristics for customers preferring spark-ignition powerplants.

Torque Converter
The Terratrac 600 featured a torque converter drive system that delivered smooth power transfer to the drivetrain, enhancing operator control in variable soil and grading conditions.

Transmission
A 4-speed transmission paired with the torque converter allowed the operator to match ground speed to task demands, whether grading, dozing, or operating mounted equipment.

Final Drive
Heavy-duty final drives transmitted power effectively to the tracks, ensuring durability under continuous load and minimizing maintenance needs in demanding environments.

Track System
The crawler undercarriage employed 14-inch wide tracks, balancing flotation and traction. The system provided stability for earthmoving while maintaining manageable ground pressure.

Electrical System
The electrical system supported starting, lighting, and essential operational needs, designed with simplicity for ease of service.

Roosa Master Pump & Diesel Injectors
The fuel system utilized a Roosa Master injection pump with diesel injectors, delivering consistent fuel metering and efficient combustion for reliable diesel performance.

Hydraulic System
The open-center hydraulic system offered approximately 19 GPM flow at 1,250 psi, supporting mounted equipment and blade control with dependable responsiveness.
