Adjustto conform and correspond to specifications.Checkto observe for satisfactory conditions, accuracy, safety or performance.Exchangeto trade a worn or failing component for a remanufactured or rebuilt component.Inspectto examine closely, in critical appraisal, while testing or evaluating components or systems.Inspect/Rebuild or Exchangeto examine closely, then making the decision on repair option (i.e. Rebuild or Exchange).Lubricateto apply a lubricant (oil, grease, etc.) as specified for reducing friction, heat and wear between solid surfaces.Protective Devicesindicators such as gauges, lights, emergency shutoffs, etc., that alert an operator that a potential problem may exist. Failure to respond to these indicators in a timely manner could result in serious engine damage.Rebuildto repair a worn or failing component with new parts, components and/or remanufactured components.Replaceto install something new, remanufactured or rebuilt in place of an existing worn or failing component.Service Hours (Electrical)records the time (clock hours) the engine is actually running but does not reflect variations in speed, load, etc. Some engines are equipped with mechanical service meters reading in Service Meter Units (SMU). The Maintenance Schedules are developed for clock hours or fuel consumption. For most users, clock hours are the standard interval for maintenance and SMU's can be roughly equal to clock hours. However, Caterpillar recommends that fuel consumption be used as the preferred method of determining intervals rather than SMU's or clock hours.Interval Categories
Engine components can generally be grouped into speed sensitive and load sensitive categories. The maintenance interval for each item listed in the Maintenance Schedule is based on either engine speed or load. Speed sensitive items such as water pumps and air compressors are not primarily affected by the operating load on your engine. The load on an engine will not significantly accelerate the repair or replacement cycle for speed sensitive items.The maintenance intervals established for speed sensitive items are based on service hours. Load sensitive items such as piston rings and cylinder liners are affected by the operating load on your engine. Generally speaking, the lower the load, the longer the engine life. 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.Load sensitive items are normally internal engine components. The amount of fuel consumed is directly related to the load on your engine.The maintenance interval for load sensitive items includes fuel consumption, since the amount of fuel consumed is directly related to the load on your engine.Caterpillar recommends performing maintenance on load sensitive items at maintenance intervals based on the quantity of fuel consumed.
