PISTON 1W1669 - Caterpillar

Before performing any operation or maintenance procedures, ensure that the Safety Information , warnings, and instructions are read and understood. To determine the maintenance intervals, use fuel consumption, service hours or calendar time, which ever occurs first. Experience has shown that maintenance intervals are most accurately scheduled on the basis of fuel consumption. For information on service hours and fuel consumption, see this Operation and Maintenance Manual , "Maintenance Recommendations" topic (Maintenance Section ).Before each consecutive interval is performed, all of the maintenance requirements from the previous interval must be performed.Note: For engines that have a shallow oil sump, change the engine oil and oil filters after 250 hours of operation. For engines that have a standard oil sump, change the engine oil and oil filters after 500 hours of operation.When Required
