OPERATING INSTRUCTIONS FOR STARTING THE ENGINE Oil Pressure Transmission While the engine is idling, check the automatic transmission (if equipped) for proper oil level and add oil as required. Observe the oil pressure gage immediately after starting the engine. A good indicator that all moving parts are getting lubrication is when the oil pressure gage registers pressure (7 psi or 50 kPa at idle speed). If no pressure is indicated within 10 to 15 seconds, stop the engine and check the lubrication system. The pressure should not drop below 36 psi or 250 kPa at 1800 rpm, and normal operating pressure should be higher.
If oil pressure does not fall within these guidelines, it should be checked with a manual gage. Fluid Leaks Look for coolant, fuel or lubricating oil leaks. If any are found, shut down the engine immediately and have the leaks repaired after the engine has cooled. Crankcase If the engine oil was replaced, stop the engine after normal operating temperature has been reached. Allow the oil to drain back into the crankcase for about twenty minutes, then check the oil level. If necessary, add oil to bring the level to the proper mark on the dipstick. Use only the heavy-duty oils recommended. Refer to the How to Select Lubricating Oil in this guide.
To avoid injury from hot oil, do not operate the engine with the rocker cover(s) removed. HOT OIL Turbocharger Make a visual inspection of the turbocharger for oil leaks, exhaust leaks, excessive noise or vibration. Stop the engine immediately if a leak or unusual noise or vibration is noted. Do not restart the engine until the cause of the concern has been investigated and corrected. Authorized Detroit Diesel service outlets are properly equipped to perform this service. Warm-up Run the engine at part throttle for about five minutes to allow it to warm up before applying a load.
Inspection While the engine is idling, inspect the transmission, check for fluid leaks, check the crankcase and turbocharger. 30 All information subject to change without notice. (Rev. 04/08) DDC-SVC-MAN-0040 0704 Copyright © 2008 DETROIT DIESEL CORPORATION
