ENGINE MAINTENANCE - Maintenance Schedule 2 Preventative Maintenance Schedule List of recommended maintenance tasks and intervals that should be performed. NOTE NOTE Perform maintenance at whichever interval occurs first. At Maintenance Schedule Intervals, perform all previous maintenance checks that are due for scheduled maintenance. This maintenance schedule is for a normal duty cycle engine operation. Severe duty/vocational applications will need to adjust mileage, kilometer, hour, or time interval based on the En- gine Lubrication and Filter Intervals. Due to the design of the crankcase ventilation module, routine service of this component is not required.
