215676 348 Revision A
5.9.4 Air Intake System
The engine requires the continuous intake of filtered air for combustion to occur.
Figure 5.52: Engine Air Intake – North America
North American models only: Engine intake air is drawn
through duct (A) from the cooling box, which pre-cleans the air,
and then through dual element filter (B). The air cleaner
canister is equipped with aspirator (C), which continuously
removes dust from the air cleaner housing. The air cleaner is
also equipped with restriction switch (D), which activates a
warning light on the cab display module (CDM) and an alarm
when the primary filter element requires cleaning.
IMPORTANT:
Do NOT run the engine when the air cleaner is disconnected or
disassembled.
If you need to replace the air filters, refer to 8.2.4 Filter Part
Numbers, page 478.
Figure 5.53: Engine Air Intake – Export
Export models only: Engine intake air is drawn through duct (A)
from the hood-mounted pre-cleaner, and then through dual
element filter (B). The air cleaner canister is equipped with
aspirator (C), which continuously removes dust from the air
cleaner housing. The air cleaner is also equipped with restriction
switch (D), which activates a warning light and an alarm on the
cab display module (CDM) when the primary filter element
requires cleaning.
IMPORTANT:
Do NOT run the engine with the air cleaner disconnected or
disassembled.
If you need to replace the filters, refer to 8.2.4 Filter Part
