FRAME AS 1R8618 - Caterpillar

Use quantity of fuel used, distance (odometer) interval or service hours, whichever occurs first.Experience has shown that maintenance intervals are most accurately scheduled on the basis of fuel consumed. However, Caterpillar recognizes that the distance (odometer) interval is most commonly used to schedule maintenance for on-highway vehicles.Daily

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. PM Level 1 assumes the use of the standard 25 U.S. quart (23.5 L) sump capacity. When equipped with the use of the larger oil filter and replacement dipstick, these maintenance items can be extended to 25,000 miles (40 000 km), 4400 gal (17 000 L) of fuel or 500 Hours.The distance (odometer) intervals shown on this schedule are based on average fuel rates. The schedule assumes 5.5 mpg (2.3 km/L). Your maintenance intervals may need adjusting if actual fuel consumption differs from average fuel consumption.1 Replacement with genuine Caterpillar Remanufactured components offers the best
