D346, D348 & D349 VEHICULAR ENGINES Caterpillar

The LUBRICATION AND MAINTENANCE CHART lists all serviceable items which are either standard equipment, or attachments commonly ordered on your model of engine.

Use the service meter to determine servicing intervals. The service meter readings are based on engine clock hours. Calendar intervals shown (daily, weekly, 2 weeks, etc.) may be used instead of service meter intervals if it is necessary to coordinate servicing schedules. At each service interval, perform the items listed, and the items listed at the previous intervals. For example, at 125 service meter units or 2 weeks, also perform those items listed under "Every 50 Service Meter Units or Weekly" and "Every 10 Service Meter Units".
