Adjust - to conform and correspond to specifications. Check - to observe for satisfactory conditions, accuracy, safety or performance. Exchange - to trade a worn or failing component for a remanufactured or rebuilt component. Inspect - to examine closely, in critical appraisal, while testing or evaluating components or systems. Inspect/Rebuilt or Exchange - to examine closely; then making the decision on repair option (Rebuild or Exchange). Lubricate - to apply a lubricant (oil, grease, etc.) as specified for reducing friction, heat and wear between solid surfaces. Protective Devices - indicators such as GSC display and alarms, 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. Rebuild - to repair a worn or failing component with new parts, components and/or remanufactured components. Replace - to 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. The Maintenance Schedules are developed for calendar time, clock hours or fuel consumption. Hours are expressed in clock hours, not service meter units (unless the service meter is a clock hour device). Hours of operation include only the time that the engine is running. An electric clock device should be connected so it is OFF when the engine is not running. Caterpillar recommends that fuel consumption be used as the preferred method of establishing intervals rather than time or clock hours. Maintenance Intervals
The Maintenance Schedule requires all previous interval maintenance items to be performed first. For instance, if the Every 250 Hour maintenance is being done, then the Daily and Every 250 Hour maintenance items must be completed BEFORE performing the Every 1000 Hour maintenance.Engines may be equipped with various optional components and the Schedule may recommend maintenance for items not installed on your engine. Simply disregard reference to any extraneous items. If unsure of any item, consult your Caterpillar dealer.Overhaul Interval
One interval for some engines is labeled TOP END because it involves removal, inspection, and rework of the cylinder head components. This interval is dependent on load-sensitive items/total amount of fuel consumed. The last interval in each chart lists the components inspected, rebuilt, exchanged or replaced at overhaul. OVERHAUL is defined as the interval at which the major wear items in the engine should be replaced. The intervals represent maintenance of a non-failed engine. In other words, the engine is being rebuilt with certain new parts replacing worn parts such as piston rings, engine rod and main bearings, valves and valve seats., etc. Incidental to the replacement of these relatively few parts is the complete inspection of all other parts that are visible during the overhaul
