RETAINER 4355617 - Caterpillar

Use fuel consumption, distance (odometer) interval or service hours, whichever occurs first.The distance (odometer) intervals shown on this schedule are based on average of 6 mpg (2.5 km/L) and use of API CF-4 engine oil. Your maintenance intervals may need to be adjusted if actual fuel consumption differs from the average.MAINTENANCE INTERVALS ARE MOST ACCURATELY SCHEDULED ON THE BASIS OF FUEL CONSUMED. THE DISTANCE (ODOMETER) INTERVALS SHOWN ON THIS SCHEDULE ARE BASED ON AVERAGE ON-HIGHWAY FUEL CONSUMPTION OF 6 MPG. Experience has shown that maintenance intervals are most accurately scheduled on the basis of fuel consumed. Rated engine speed and load factor are also important for some components. However, Caterpillar recognizes that the distance (odometer) interval is most commonly used to schedule maintenance for on-highway vehicles. Maintenance Schedules are developed for distance (odometer) intervals, clock hours or fuel consumption. For most users, distance (odometer) intervals are the standard interval for maintenance. However, Caterpillar suggests that fuel consumption be used as the preferred method of determining intervals rather than distance (odometer) intervals.Follow the recommended Maintenance Schedule with emphasis on emission related components, air cleaner, oil, oil filter, fuel and fuel filter maintenance found in this publication.
