Engine Configuration

The Cat D311 engine is a four-cylinder, inline engine that operates on a four-stroke combustion cycle. It has a displacement of 4.4 liters (269 cubic inches) and a bore and stroke of 105 mm (4.13 inches) and 127 mm (5.00 inches) respectively. This configuration ensures smooth and efficient power delivery, allowing the engine to perform optimally in various operating conditions.

Engine Oil Specs & Service Intervals

Proper maintenance and regular oil changes are crucial for the longevity and performance of any engine, including the Cat D311. Here are the recommended engine oil specifications and service intervals for the Cat D311 engine:

  • Engine Oil Type: It is recommended to use high-quality diesel engine oil that meets the Cat ECF-1 specification. This ensures optimal lubrication and protection for the engine components.
  • Oil Viscosity: The recommended oil viscosity for the Cat D311 engine is SAE 15W-40. This viscosity provides excellent lubrication in both high and low-temperature conditions.
  • Oil Capacity: The engine oil capacity of the Cat D311 engine is approximately 9.5 liters (10 quarts). It is important to maintain the oil level within the recommended range for proper lubrication.

Service Intervals

To maintain the performance and reliability of the Cat D311 engine, it is essential to follow the recommended service intervals. Here are the general service intervals for the Cat D311 engine:

  1. Oil Change: The engine oil should be changed every 250 hours of operation or every 6 months, whichever comes first. Regular oil changes help remove contaminants and ensure proper lubrication.
  2. Oil Filter Replacement: The oil filter should be replaced during every oil change. This helps remove impurities from the oil and prevents them from circulating in the engine.
  3. Air Filter Replacement: The air filter should be inspected regularly and replaced as needed. A clean air filter ensures proper airflow to the engine and prevents dust and debris from entering the combustion chamber.
  4. Fuel Filter Replacement: The fuel filter should be replaced every 500 hours of operation or every year, whichever comes first. This helps maintain fuel quality and prevents contaminants from reaching the engine.
  5. Regular Inspections: In addition to regular oil and filter changes, it is important to conduct routine inspections of the engine components, such as belts, hoses, and cooling system, to identify any potential issues and address them promptly.
