Maintenance and operation practices affect component service life when operating the engine in severe service applications.The level of maintenance an engine receives is crucial to the engine's service life. Other major factors affecting service life are operating speed and loads.Reduce the maintenance intervals for engines that operate under severe or dusty conditions, or where average operating speeds are less than 32 km/h (20 mph). Examples of such operation are inner city garbage compactors, delivery vehicles, and drill rigs.The following conditions can indicate severe service operation:* Operating with more than 22 700 kg (50,000 lb) gross vehicle weight and other high load factor operation such as off-highway* Frequent high altitude operation above 1525 meters (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 three minute cool down periods after high load factor operation)
