Checkto observe for satisfactory conditions, accuracy, safety or performance.Inspectto examine closely, in critical appraisal, while testing or evaluating components or systems.Lubricateto apply a lubricant (oil, grease, etc.) as specified for reducing friction, heat and wear between solid surfaces.Replaceto install something new, remanufactured or rebuilt in place of an existing worn or failing component.Rebuildto repair a worn or failing component with new parts, components and/or remanufactured components.Exchangeto trade a worn or failing component for a remanufactured or rebuilt component.Protective Devicesindicators such as gauges lights, emergency shutoffs, etc., that alerts an operator that a potential problem may exist. Failure to respond to these indicators in a timely manner could result in engine failure.Service Hours (Electrical)records the time (clock hours) the engine is actually running but does not reflect variations in speed, load, etc.Adjustto conform and correspond to specifications.Interval Categories
Engine components can generally be grouped into "speed sensitive" and "load sensitive" categories. Therefore, the maintenance interval for each item listed in the "Maintenance Management Schedule" is primarily based on the item and its relationship to either engine speed or load. Speed sensitive items such as water pumps, air compressors, etc., are not primarily affected by the load on your engine during operation. The load on an engine will not significantly accelerate the repair or replacement cycle for speed sensitive items.Therefore, the maintenance intervals established for speed sensitive items are based on miles (kilometers) or service hours, whichever occurs first. Load sensitive items such as piston rings, cylinder liners, etc., are affected by the load on your engine during operation. Generally speaking, the lower the load, the longer the engine life and conversely, the higher the load, the shorter the engine life. A heavy load on an engine will accelerate the repair or replacement cycle for load sensitive items.Therefore, the maintenance interval for load sensitive items also includes quantity of fuel used, since the amount of fuel consumed is directly related to the load on your engine.Load sensitive items are normally internal engine components. The amount of fuel consumed is directly related to the load on your engine. Since the amount of fuel consumed is a better indicator of performing an overhaul than miles (kilometers) or service hours, Caterpillar recommends performing an overhaul on these items at the specified maintenance interval based on the quantity of fuel consumed.Interval to Overhaul
The specified overhaul interval for this engine rated 350 hp (261 kw) at 1800 rpm and below is "Every 100,000 Gallons (380 000 L) of Fuel or 600,000 Miles (960 000 km) or 10,000 Service Hours." This includes all power ratings BELOW 350 hp (261 kw).The specified overhaul interval for this engine rated 350 hp (261 kw) at 2100 rpm and up is "Every 100,000 Gallons (380 000 L) of Fuel or 500,000 Miles (800 000 km) or 10,000 Service Hours." This includes all power ratings ABOVE 350 hp (261 kw). Two Maintenance Management charts follow. Ensure the correct chart is selected for the engine being maintained. PM Level means Preventive Maintenance Level.
