1 Standby generator applications may allow intervals up to every 2 weeks.
2 Replace primary air cleaner element when restriction indicator shows a vacuum of 625 mm (25 in) H2O. If not equipped with indicator, replace air cleaner elements at 500 hours or 12 months, whichever occurs first.
3 During engine break-in, change the oil and filter for the first time before 100 hours of operation.
4 Service intervals depend on sulfur content of the diesel fuel, oil pan capacity, and the oil and filter used, which means that intervals may be REDUCED. (See DIESEL ENGINE OIL AND FILTER SERVICE INTERVALS in Fuels, Lubricants, and Coolant Section.)
5 Replace crankshaft vibration damper every 4500 hours or 60 months, whichever occurs first.
6 If John Deere COOL-GARD is used, the flushing interval may be extended to 3000 hours or 36 months. If John Deere COOL-GARD is used and the coolant is tested annually AND additives are replenished as needed by adding a supplemental coolant additive, the flushing interval may be extended to 5000 hours or 60 months, whichever occurs first.
