and maintenance practices affect the service life of the components when the engine is operated in severe service applications.The level of maintenance is crucial to the service life of the engine. Other major factors that affect service life are operating speed and loads.The conditions that follow can indicate severe service operation:
Operation above 36,320 kg (80,000 lb) gross vehicle weight (GVW) and other high load factor operations (such as off-highway)
Frequent high altitude operation above 1525 m (5000 ft)
Extended operation at low idle
Arctic operation (regular cold starts at temperatures below −18 °C (0 °F))
Extending maintenance beyond the recommended maintenance intervals
Frequent hot shutdowns (minimum five minute cool down periods after high load factor operation)
Use of fuels that are NOT recommended by Caterpillar in the Fuel Specifications
Extreme ambient temperature conditions that may cause the lubricating properties of the fuel to diminish
Frequent plugging of the fuel filter
Extended maintenance intervals of the fuel system
Inadequate maintenance of fuel storage tanks (excessive water, sediment, microorganism growth, etc.)
