The following table correlates approximate engine hours based on load factor and target fuel burn number.
Table 1
Engine Overhaul
Load Factor <28% 28%-32% 33%-37% >37%
Hours 24,000 20,000 18,000 16,000
Gallons 1,125,000 1,125,000 1,125,000 Note: Below a 28% Load Factor, engine operating hours will become the limiting factor.Severe operation may reduce the hours to overhaul per chart above.Severe operation can accelerate component wear. Engines that are operating under severe conditions may need more frequent maintenance intervals for the following reasons:
Maximum reliability
Retention of full service lifeBecause of individual applications, it is not possible to identify all the factors which can contribute to severe operation. Consult your Cat dealer about the maintenance that is needed for your specific engine.The following factors can contribute to severe operation: environment, improper operating procedures, and improper maintenance practices.Environmental Factors
Altitude
High altitude operation may increase the soot level in the engine oil. Increased levels of soot can cause oil deterioration, deposit formation, and abnormal wear. More frequent oil drains and premium performance lubricants can offset these negative factors.Note: Refer to Special InstructionREHS3797 for more information.Extreme Ambient Temperatures
Extended operation in environments that are extremely cold or hot can damage components. Valve components can be damaged by carbon buildup if the engine is frequently started and stopped in very cold temperatures. Extremely hot inlet air reduces the performance capabilities of the engine.Note: Refer to Special Publication, SEBU5898, "Cold-Weather Recommendations" for more information.Cleanliness
Unless the equipment is cleaned regularly, extended operation in a dirty environment and in a dusty environment can damage components. Built up mud, dirt, and dust can encase components. This can make maintenance difficult. The buildup can contain corrosive chemicals. Corrosive chemicals and salt can damage some components.Improper Operating Procedures
Extended operation at low idle
Minimum cool down periods after high load factor operation
Operating the engine beyond the guidelines for the engine rating
Operating the engine at loads that are greater than the rated load
Operating the engine at speeds that are greater than the rated speed
Use of the engine for an application that is not approvedImproper Maintenance Practices
Extension of maintenance intervals
Not using recommended fuel, lubricants, and coolant/antifreeze
