Turbocharger; Air Cleaners - Peterbilt 348 2017 Operator's Manual

Turbocharger

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.
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)
High Frequency Vibration: Vibration
may indicate turbo rotor imbalance.
Have your dealer investigate this
immediately. If you detect any
deficiencies, take the vehicle to an
authorized dealer for servicing. Delay
could lead to severe and expensive
damage to your vehicle.

Air Cleaners

The following service information is
basic to all air cleaner makes and
models.
CAUTION
Failure to replace air filter at proper
intervals may result in passage of
dirt/debris into the engine or the
"dusting" of an engine resulting in
significant engine damage.
Service the filter elements when the
Air Cleaner Restriction gauge (option)
locks in the extreme High position.
Have the element serviced at a
Peterbilt Dealer or Authorized Service
Center. Paper elements require care
and proper handling, because they are
critical to engine service life. Service
the air cleaner periodically. If the
vehicle operates in areas with heavy
dust, maintenance should be more
