Engine Operation Checking the Transmission While the engine is idling, check the automatic transmission (if equipped) for proper oil level and add oil as required. For additional information on checking the transmission, Refer to the Original Equipment Manufacturer (OEM) literature and the Transmission Fluid Service brochure DDC-SVC-BRO-0118. Checking the Turbocharger Check the turbocharger as follows: 1. Make a visual inspection of the turbocharger for oil leaks, exhaust leaks, excessive noise, or vibration. 2. If a leak, unusual noise, or vibration is noted, stop the engine immediately. Do not restart the engine until the cause of the concern has been investigated and corrected.
Authorized Detroit™ service outlets are properly equipped for this type of service. Monitoring the Engine Speed During operation of the vehicle, the operator should limit the engine speed to 1900 rpm or less. No extra engine power is achieved at engine speeds above 1900 rpm. Shifting gears without pressing the clutch, or using the engine brakes to reduce engine speed, may result in serious powertrain damage due to higher engine speeds. Never exceed 2000 rpm; higher engine speeds may result in extensive engine damage. NOTICE: Any engine overspeed (engine speed exceeds 2500 rpm) while the vehicle is moving (vehicle speed over 0 MPH) is considered to be an operator-induced engine overspeed.
Any mechanical engine failure within 2000 miles (3218 km) of an operator-induced engine overspeed event will not be eligible for warranty coverage. Shutting Down the Engine Immediately shutting down the engine should be avoided. Shutting the engine off immediately retains more cylinder block heat than if the engine runs at idle for five minutes. If any of the following conditions occur, shut down the engine immediately: The oil pressure swings back and forth or falls sharply. Engine power and rpm fall, even though the accelerator pedal remains steady. The exhaust pipe gives off heavy smoke. The coolant and/or oil temperature climb abnormally.
Abnormal sounds suddenly occur in the engine or turbocharger. Contact an authorized Detroit™ service outlet if any of the above conditions is present. 28 All information subject to change without notice. Copyright © 2022 DETROIT DIESEL CORPORATION DDC-SVC-MAN-0217
