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.
Checking the Axial Power Turbine
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.
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.
