ENGINE Air Intake System Turbocharger Engine heat, vibration, and age combine to loosen air intake connections and cause cracks in the tubing and elbows. Leaks in the intake system allow abrasive dust to enter the engine and quickly cause expensive damage. During your daily walk-around inspection, carefully check all tubing, elbows, clamps, supports and fasteners for condition and tightness. Do not use air intake pipes and con- nections as a step or to pull your- self up. This could loosen the con- nections and open the system to un- filtered air which could damage the engine. CAUTION When servicing the air intake and exhaust systems on a turbocharged engine, check the items listed below.
WARNING! Do not operate engine with tur- bocharger intake piping discon- nected. A suction is created when the engine is running. This suction could draw your hand or anything else near it into the impeller fan. You could be injured. Always keep the intake piping connected when you will be running the engine. Check the Charge-Air-Cooler for air leaks annually. The air leaks can be caused by cracked tubes or header. For service see your authorized dealer. 5 Lubricating System: Check the oil lines, housing, and connections. Look for leaks, damage, or deterioration. Leaks could mean you have damaged oil lines or oil seals. Manifold:
With the engine operating, check for leaking manifold or flange gaskets. (03/17) Y53-6077-1B1 5-107
