Maintenance Guidelines
Maintenance Guidelines - Overview
Cummins Inc. recommends that the engine be maintained according to the Maintenance Schedule in this section. If the engine is operating in ambient temperatures below -18°C (0°F) or above 38°C (100°F), perform maintenance at shorter intervals. Shorter maintenance intervals are also required if the engine is operated in a dusty environment or if frequent stops are made. Contact your authorized dealer and local Cummins Authorized Repair Location for recommended maintenance intervals. Some of these maintenance procedures require special tools or must be completed by qualified personnel. Contact your local Cummins Authorized Repair Location for details. If your engine is equipped with a component or accessory not manufactured by Cummins Inc., refer to the component manufacturer's maintenance recommendations. Use the chart provided in this section as a convenient way to record maintenance performed.
Tool Requirements
Most of the maintenance operations described in this manual can be performed with common hand tools (metric and S.A.E. wrenches, sockets, and screwdrivers). The following is a list of special service tools required for some maintenance operations:

Reference the appropriate sections for complete inspection and maintenance procedures. NOTE: These maintenance intervals must be performed at hours or months, whichever interval occurs first. At each scheduled maintenance interval, perform all previous maintenance procedures that are due for scheduled maintenance. NOTE: Follow the gear manufacturer's recommended maintenance procedures for checking, filling, and changing oil. Some gear manufacturers require an initial oil change at low hours, in addition to their regular maintenance.
QSM11 Cummins Engine QSM11CUMMINSENG Page 53
NOTE: Fuel burn is the most accurate method for determining oil change intervals. Oil change intervals can be required more frequently, depending on the quality of the oil available. Reference the Oil Drain Interval table for marine and industrial engines in this procedure for additional oil change intervals. NOTE: Do not change the coolant filter if the SCA concentration level is over three units. NOTE: Depending upon the quality of electrical bonding and water conditions, increased maintenance of the zinc anode plugs could possibly be necessary.
Oil Drain Intervals
QSM11 Industrial Engines - Oil Drain Intervals by Duty Cycle (hours) Severe Heavy Medium Light
Fuel Consumption Greater than 13 gallon / hours 10 - 13 gallon / hours 8.5 - 10 gallon / hours Less than 8.5 gallon / hours API CF-4 150 200 250 300 API CG-4 250 300 400 500 API CH-4 or ACEA E5 300 350 500 600 CES20076 or 350 350 550 700 CES20077 1. Valvoline® Premium Blue® and Premium Blue® 2000 meet 20076 standards. 2. Limit oil change interval to 250 hour maximum for all oil grades if 40 percent of the operating time is in ambient temperatures above 38°C (100°F) to prevent engine damage due to oil degradation resulting from high oil temperatures. 3. Cummins does not recommend the use of CE or CD grade oils. If CD or CE oils must be used, make the oil drain intervals half of the API CF-4 values. 4. Engine oil drain intervals need to be reduced by 50 percent when fuel sulfur content exceeds 0.5 percent.
