Item 8- Exhaust System; Item 9- Air Compressor; Item 10 - Aftertreatment System (Ats) - Detroit Diesel MBE 900 Operator's Manual

NOTICE:
Do not allow the air inlet restriction to
exceed 5.5 kPa (22 in. H2O) under
any engine operating conditions.
A clogged air cleaner element will
cause excessive intake restriction
and reduced air supply to the
engine resulting in increased fuel
consumption, inefficient engine
operation and reduced engine life.
Inspect the entire air system for leaks
daily. Look especially for torn air inlet
piping or boots and loose or damaged
clamps. Have worn or damaged parts
repaired or replaced, as required.
Retighten loose connections.
Air Cleaner Replacement – Dry
type air cleaner elements should be
replaced after one year of service or
when the maximum allowable air
intake restriction has been reached,
whichever comes first.
Air-to-Air Charge Cooler –
Periodically inspect the air-to-air
charge cooler for buildup of dirt, mud,
etc. and wash off using a mild soap
solution. Check the charge cooler,
ductwork, and flexible connections for
leaks and have repaired or replaced,
as required.
Item 8– Exhaust System

and other connections should be

inspected for leaks. The exhaust pipe
rain cap should be checked for proper
operation, if so equipped. With the
introduction of an Aftertreatment
system, the sealing of the exhaust
system is critical and should be
inspected regularly.
Item 9– Air Compressor
The air compressor incorporates
three of the major systems of a diesel
engine (air, lubrication, and coolant).
Proper inspection of air compressor
would include inspecting for air, oil,
and coolant leaks. Due to inadequate
internal sealing air compressors,
when failed, can produce excessive
crankcase pressure or allow an engine
to ingest oil.
Item 10 – Aftertreatment System
(ATS)
There is a need to periodically remove
accumulated ash, derived from engine
lube oil, from the filter. This ash
does not oxidize in the filter during
the regeneration process and must
be removed through a cleaning
procedure. All Detroit Diesel ATD
equipped engines will illuminate a
dashboard warning lamp indicating
the need for ash cleaning.
