NOTE: If the type/oil capacity of the oil pan is not known:
• Contact a Cummins® Distributor/Dealer.
• Determine the capacity of the oil pan option for the engine being serviced by using QuickServe™ Online and the
engine serial number.
• Fill the lubricating oil pan to the smallest oil pan capacity listed for the engine being serviced. Then add 0.95 liters
[1 qt] of oil at a time until it reaches the high mark on the dipstick. Record the number of quarts added so that
capacity is known the next time the oil is drained.
