Figure 5.52: Engine Air Intake
Engine intake air is drawn through a duct (A) from the hood
mounted pre-cleaner that pre-cleans the air, and then
through a dual element filter (B). The air cleaner canister is
equipped with an aspirator (C) that continuously removes
dust from the air cleaner housing. The air cleaner is also
equipped with a restriction switch (D) which activates a
warning light on the cab display module (CDM) with an
alarm when the primary filter element requires cleaning.
If you need to replace filters, refer to 8.2.4 Filter Part Numbers, page 462 .
IMPORTANT:
•
Do NOT run engine with air cleaner disconnected or disassembled.
•
Over-servicing the filter element increases the risk of dirt being ingested by the engine and severely damaging
the engine.
•
Filter servicing should only be performed when the CDM indicates ENGINE AIR FILTER or at the specified
interval. Refer to
5.12.1 Maintenance Schedule/Record, page 415 .
Air Filter Restriction Indicator
During engine operation, the indicator shows the vacuum in inches of H
2
O and kPa. As dirt accumulates in the filter,
the restriction increases.

Figure 5.53: Air Filter Restriction Indicator
When the indicator gauge reaches the CHANGE FILTER
mark (A), 25 in. of H
2
O (6.20 kPa), a warning tone will
sound and the cab display module (CDM) will indicate the
filter requires servicing.
IMPORTANT:
Over-servicing the filter element increases the risk of dirt
being ingested by the engine, causing severe damage.
Service air filter ONLY IF indicator reaches the CHANGE
FILTER mark (A) or 25 in. H
2
O (6.20 kPa).
IMPORTANT:
After servicing filters, press the RESET button on the end of
the indicator (B).
