ELECTRONICS GP-MACHINE 2258017 - Caterpillar

TYPE="LEVEL" DEPTH="1" @@@-->Maintenance Information
The operating conditions of an engine affect the maintenance intervals and the time between overhauls for the engine. The following conditions affect the maintenance intervals and the expected overhaul interval for the engine.Severe Operation
Severe operation is the use of an engine that exceeds current published standards for the engine. Caterpillar maintains standards for the following engine parameters:
Horsepower
Range of rpm
Fuel consumption
Fuel quality
Altitude
Maintenance intervals
Selection of oil
Selection of coolant
Environmental qualities
InstallationRefer to the standards for your engine or consult your Caterpillar dealer in order to determine if your engine is operating within the defined parameters.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 lifeIndividual applications make it impossible to identify all of the factors which can contribute to severe operation. Consult your Caterpillar 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
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: See this Operation and Maintenance Manual, "Cold Weather Operation" topic (Operation Section), or see Supplement, SEBU5898, "Cold Weather Recommendations".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 operating environment 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 antifreeze/coolant solutionsOverhaul Information
Caterpillar makes the following recommendations for the timing of the overhaul procedures for your engine. The intervals may be extended based on individual application and load factors. Contact your Caterpillar dealer for further information about the optimal maintenance interval for the overhaul procedures.
Table 1
Overhaul Procedure Recommended Interval
Major Overhaul Every 280000 L (75000 US gal) or 5000 SH Note: Refer to this Operation and Maintenance Manual, "Overhaul (Major)" for further information about the major overhaul.Reduced hours of operation at full load will result in a lower average power demand. A decreased average power demand should increase both the engine service life and the overhaul interval.The need for an overhaul is generally indicated by increased fuel consumption and by reduced power.The following factors are important when a decision is being made on the proper time for an engine overhaul:
The need for preventive maintenance
The quality of the fuel that is being used
The operating conditions
