Heavy equipment engines are built to last, but only with proper care. Whether you operate Komatsu, Caterpillar, or Volvo machinery, following a strict maintenance schedule will save you thousands in repair costs.
Oil is the lifeblood of your engine. For most heavy-duty diesels, oil change intervals fall between 250–500 hours depending on load and environment. Always use the manufacturer-recommended viscosity grade.
A clogged air filter starves your engine of oxygen, leading to incomplete combustion and black smoke. Check primary air filters every 250 hours and replace when restriction indicators trigger.
Low coolant causes overheating — one of the top causes of catastrophic engine failure. Check coolant concentration every 500 hours and flush the system as per the service manual.
Cutting corners with low-quality filters or gaskets can void warranties and cause premature wear. TECFORD stocks OEM-grade components for all major brands.
Following these steps will easily extend engine life beyond 15,000 hours on most platforms.
