Routine Preventive Maintenance Routine Preventive Maintenance Routine Preventive Maintenance This section describes the items listed in the maintenance interval tables. The Daily instructions apply to routine or daily starting of the engine. They do not apply to a new engine or one that has been operated for a considerable period of time. Monitoring the Lubricating Oil Perform the following maintenance on the lubricating oil: 1. Check the oil level daily with the engine stopped and on a level surface. If the engine has just been stopped and is warm, wait approximately 20 minutes to allow the oil to drain back into the oil pan before checking. NOTE:
The dipstick has a positive locking device such as a lever or twist- lock design that must be disengaged before pulling the dipstick out of the guide tube. Use a shop rag to wipe off the end of the dipstick. Wait 15 seconds to allow any crankcase pressure to dissipate through the guide tube and let the oil level settle in the oil pan. 2. Add the proper grade of oil to maintain the correct level on the dipstick. Remove the dipstick from the guide tube. Before adding lubricating oil, refer to "How to Select Lubricating Oil." NOTICE: Do NOT fill beyond the maximum fill level on the dipstick, since overfilling may result in high oil consumption and possible severe engine damage. NOTE:
If the engine operating temperature is below 60° C (140° F), the engine must be on a level surface and then shut down for 60 minutes for an accurate oil level reading. Otherwise, the engine must be brought up to an operating temperature of 60° C (140° F), parked on a level surface and then shut down for 20 minutes for an accurate oil level reading. 3. Reinstall the dipstick and make sure it is fully inserted into the guide tube. Remove the dipstick and read the oil level dipstick. NOTICE: Do not add oil if the oil reading is in the crosshatch area on the dipstick. There are approximately 4.0 L (4.2 qts) from the minimum mark to the maximum mark on the dipstick.
Overfilling the oil pan can cause engine damage. 68 All information subject to change without notice. Copyright © 2017 DETROIT DIESEL CORPORATION DDC-SVC-MAN-0192
