AIR SYSTEM<br />
condensation. Under these conditions, the presence<br />
of small amounts of moisture is normal and should not<br />
be considered as an indication that the dryer is not<br />
performing properly.<br />
• An outside air source may have been used to charge<br />
the air system, in which case this air did not pass<br />
through the drying bed.<br />
Air Intake System<br />
Engine heat, vibration, and age combine to loosen air<br />
intake connections and cause cracks in the tubing and<br />
elbows. Leaks in the intake system allow abrasive dust to<br />
enter the engine and quickly cause expensive damage.<br />
During your daily walk-around inspection, carefully check<br />
all tubing, elbows, clamps supports and fasteners for condition<br />
and tightness.<br />
• Under normal operating conditions, <strong>Peterbilt</strong> recommends<br />
complete disassembly and cleaning of the air<br />
intake system at each 25,000 mile (40,000 km).<br />
Under severe operating conditions, the disassembly<br />
and cleaning should be more frequent. Replace any<br />
defective parts. With the possible exception of mounting<br />
brackets, do not repair defective parts.<br />
PREVENTIVE MAINTENANCE<br />
• Check the Charge-Air-Cooler for air leaks annually.<br />
The air leaks can be caused by cracked tubes or<br />
header. For service see your <strong>Peterbilt</strong> Dealer or<br />
Authorized Service Center.<br />
Turbocharger<br />
When servicing the air intake and exhaust systems on a<br />
turbocharged engine, check the items listed below.<br />
WARNING! Do not operate engine with the turbocharger<br />
intake piping disconnected. A suction<br />
is created when the engine is running.<br />
This suction could draw your hand or anything<br />
else near it into the impeller fan. You<br />
could be killed or seriously injured. Always<br />
keep the intake piping connected when you<br />
will be running the engine.<br />
Lubricating System: Check the oil lines, housing, and<br />
connections. Look for leaks, damage, or deterioration.<br />
Leaks could mean you have damaged oil lines or oil seals.<br />
Manifold: With the engine operating, check for leaking<br />
manifold or flange gaskets.<br />
