Operating Instructions for Starting the Engine 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. Check the axial power turbine for excessive noise or vibration. Stop the engine immediately if unusual noise or vibration is noted. Do not restart the engine until the cause of the concern has been investigated and corrected.
Checking the Axial Power Turbine Avoid Unnecessary Idling Whenever possible, unnecessary idling should be avoided. During long engine idling periods with the transmission in neutral, the engine coolant temperature may fall below the normal operating range. The incomplete combustion of fuel in a cold engine will cause crankcase oil dilution, formation of lacquer or gummy deposits on the valves, pistons, and rings, and rapid accumulation of sludge in the engine. When prolonged idling is necessary, maintain at least 900 rpm. 30 All information subject to change without notice. Copyright © 2019 DETROIT DIESEL CORPORATION DDC-SVC-MAN-0209
